  • Page 229: Vertical Acquisition Window Considerations

    Waveform data outside of the vertical acquisition window is clipped; that is, the data is limited to the minimum or maximum boundaries of the vertical acquisition window. This causes inaccuracies in amplitude-related measurements. For more information see Vertical Acquisition Window Considerations on page 229. Adjusted Horizontal Acquired waveform Scale...
  • Page 230 Note Amplitude-related automatic measurements (for example, peak-to-peak and RMS) will be accurate for vertical windows like those shown in Figures A and B below because neither waveform is clipped (that is, both waveforms are acquired). But if signal amplitude were to extend outside the vertical acquisition window, the data acquired is clipped.

  • Page 231: Horizontal Acquisition Window Considerations

    Horizontal Acquisition Window Considerations The instrument lets you define the horizontal acquisition window, that is, set several parameters that determine the segment of an incoming signal that becomes the waveform record when acquired. (For background, go to Waveform Record on page 235.) These common parameters specify a horizontal acquisition window that is applied to all channels in parallel.

  • Page 232: Autoset Considerations

    Autoset Considerations Autoset acquires samples from the input signal and attempts to take the following actions based on the input data: Evaluate the amplitude range of the input signals and set the size and vertical offset of the vertical acquisition window to acquire the signal with good resolution, but without clipping. Set the trigger to the approximate midlevel of the signal being Autoset and switches to edge trigger mode.

  • Page 233: Independent Versus Shared Window

    For example, at 200 ps/div and 10 divisions, the record length must be 500 points: Max Rec Length 500 samples = (10 divs x 200 ps/div) ÷ 4 ps/sample Max Rec Length = 500 samples Note As implied from the operation just described, Resolution and the equivalent elements, Sample Interval and Sample Rate, are derived and cannot be set directly.

  • Page 234: Acquisition Hardware

    Acquisition Hardware Before a signal can be acquired, it must pass through the input channel where it is scaled and digitized. Each channel has a dedicated input amplifier and digitizer, as shown in the following figure; each channel can produce a stream of digital data from which the instrument extracts waveform records.

  • Page 235: Sampling Modes

    Sampling Modes The acquisition system can process the data as it is acquired, averaging or enveloping the waveform data to produce enhanced waveform records. Once the waveform record exists (enhanced or not), you can use the post processing capabilities of the instrument to further process that record: perform measurements, waveform math, and so on.

  • Page 236: Interleaving

    Interleaving The instrument can interleave channels to attain higher real-time digitizing rates and longer record length when only 1 or 2 channels are turned on without equivalent-time sampling. The instrument applies the resources of unused channels (that is, channels that are turned off) to sample those that are in use (turned on).

  • Page 237: Trigger Sources

    Triggers create meaningful waveforms from signal displays. This instrument has simple edge triggers as well as a variety of advanced triggers. The Trigger Event The trigger event establishes the time-zero point in the waveform record. All waveform record data are located in time with respect to that point. The instrument continuously acquires and retains enough sample points to fill the pretrigger portion of the waveform record (that part of the waveform that is displayed before, or to the left of, the triggering event on screen).

  • Page 238: Trigger Modes

    Logic triggers are special-purpose triggers that are primarily used with digital logic signals. Two of the types, Pattern and State, trigger the instrument based on the Boolean operator you select for the trigger sources. A third type, Setup and Hold, triggers when data in one trigger source changes state within the setup and hold times that you specify relative to a clock in another trigger source.

  • Page 239: Trigger Coupling

    At the longer holdoff time for the top waveform, unstable triggering occurs. With a shorter holdoff set for the bottom waveform, triggers all occur on the first pulse in the burst to remedy the unstable trigger. The Holdoff setting range is 1.5 µs (minimum holdoff available) to 12 seconds (maximum holdoff available).

  • Page 240: Advanced Triggering

    Advanced Triggering You can check the advanced trigger status in the readout. The readout indicates the trigger type and then shows sources, levels, or any other parameters that are important for the particular trigger type. For details on advanced triggers see pages 240–244. Glitch Trigger A glitch trigger occurs when the instrument detects a pulse narrower (or wider) than some specified time.

    Acquisition Preview The acquisition preview attempts to show what the next acquisition will look like when the acquisition is delayed due to slow triggers or long acquisition duration, or when the acquisitions have stopped. Acquisition preview recalculates math waveforms, but does not represent changes in trigger levels, trigger modes, or different acquisition modes.

    In general, the method of adjusting (vertically scaling, offsetting, positioning, and so on) the waveform display is from the front-panel vertical SCALE and POSITION knobs. Note that math and reference waveforms are scaled and positioned from their setup control windows. For channel waveforms, the vertical and horizontal controls that you set also adjust the instrument acquisition parameters.

    Operations on the Time Base In general, to adjust the time base, use the front-panel horizontal SCALE, RESOLUTION, and POSITION knobs. Only channel waveforms can be set directly. Here are some key points to remember about how horizontal operations relate to the waveform types: Reference waveforms are shown with the horizontal settings in effect at the time that they are saved.

  • Page 256: Using The Multizoom Feature

    Using the MultiZoom Feature Use the instrument MultiZoom feature to magnify an acquisition vertically, horizontally, or in both dimensions to let you see the fine detail in your signals without changing the acquisition parameters (sample rate, record length, and so on). For example, to temporarily expand the front corner of a pulse to inspect its aberrations, push the front-panel MultiZoom button to expand it horizontally and vertically.

  • Page 257: Cursor Measurements

    Reference Levels Method A second set of levels affect the fidelity of time-related measurements. For example, the measurement system calculates rise time from the waveform edge that transitions from the Low to the High reference levels. The instrument provides the following calculation methods (see the following figure): Relative Reference is calculated as a percentage of the High/Low range.
  • Page 258 You cannot move a cursor off the graticule unless you are in Zoom mode. Also, if you resize waveforms, the cursors do not track. That is, a cursor stays at its screen position, ignoring changes to horizontal and vertical scale and position and vertical offset (Waveform and Screen cursors will track a waveform vertically).

  • Page 259: Cursor Types

    Cursor Units Depend on Sources A cursor that measures amplitude or time will read out in the units of its source as indicated in the table below. Note mixed sources require delta cursor readouts to use the units of the Cursor 1 source.

  • Page 260: Histograms

    Cursor function Measurements T2 = Time @ Cursor 2 with respect to the trigger point ∆T = Time @ Cursor 2 - Time @ Cursor 1 Time is divisions of displacement of the cursor from its source trigger point multiplied by the source in time/div. Waveform cursors measure vertical parameters (typically volts) and horizontal parameters (typically time or frequency) simultaneously.

  • Page 261: Math Waveforms

    Math Waveforms Once you have acquired waveforms or taken measurements on waveforms, the instrument can mathematically combine them to create a waveform that supports your data-analysis task. For example, you might have a waveform clouded by background noise. You can obtain a cleaner waveform by subtracting the background noise from your original waveform.
  • Page 262 This instrument supports mathematical combination and functional transformations of waveforms it acquires. The following figure shows this concept: You create math waveforms to support the analysis of your channel and reference waveforms. By combining and transforming source waveforms and other data into math waveforms, you can derive the data view that your application requires.

Roll Mode: Math is not allowed in roll mode until you push STOP. Different Length Sources: If you use two waveforms (channel and reference waveforms) of different lengths, the length of the math waveform will be the shorter of the two lengths.

  • Page 264: Math Waveform Sources

    Offset, Position, and Scale The settings that you make for offset, scale, and position affect the math waveform you obtain. Here are some tips for obtaining a good display: Scale and position the source waveform so that it is contained on the screen. (Off-screen waveforms may be clipped, resulting in errors in the derivative waveform).

    Cursor Measurements You can also use cursors to measure derivative waveforms. Use the steps in Taking Cursor Measurements on page 355. When using that procedure, note that the amplitude measurements on a derivative waveform will be in volts per second rather than in volt-seconds as is indicated for the integral waveform measured in the procedure.

  • Page 267: Defining Spectral Math Waveforms

    scale is the output scale factor T is the time between samples Since the resultant math waveform is an integral waveform, its vertical scale is in volt-seconds (its horizontal scale is in seconds). The source signal is integrated over its entire record length; therefore, the math waveform record length equals that of the source waveform.

  • Page 268: Using The Spectral Math Controls

    Spectral Averaging: You can turn on averaging in the frequency domain for phase and magnitude waveforms. Multiple Analyzer Control Locks: Up to four spectral analyzers can be used simultaneously. They can all be assigned to different gates on the same source waveform or to different channel sources.

  • Page 269: Using The Gating Controls

    Examples of how duration and resolution affect the acquired waveform are shown in the following figure. Using the Gating Controls Gating determines which portion of the acquired waveform is transformed into the frequency domain. The gate has a position and a width control. The gate position is the time in seconds from the trigger location to the center 50% position of the gate interval (see the figure below).

  • Page 270: Using The Frequency Domain Controls

    The width of the gate affects the resolution bandwidth of the spectral analyzer. Gate width has units of seconds. The resolution bandwidth directly controls the gate width, but the numerical value is entered in units of Hz. Therefore, the time domain gate markers move as you adjust the resolution bandwidth control.

  • Page 271: Using The Magnitude Controls

    Using the Magnitude Controls Vertical units can be either linear or log. You may select these choices by clicking the Math menu button. Then select the Spectral Analysis Setup command. On the Mag tab, select the desired scale type from Linear, dB, or dBm. Linear: When the spectrum is linear magnitude the vertical units are the same as the source waveform.
  • Page 272 Reference Level: This sets the vertical position of the displayed spectrum. Its value is the magnitude at the top of the display screen. When this control is adjusted, the spectral waveform along with its zero reference marker move vertically on the screen as shown. This control does not change the spectral data.

  • Page 273: Using The Phase Controls

    Using the Phase Controls You can set the vertical units to Degrees, Radians, or Group Delay in seconds. To do this, click the Math toolbar button, click Spectral Analysis Setup, and select the Phase tab. Then select the desired scale type from Degrees, Radians, or Group Delay. Phase Reference Position: Phase is a relative measurement that must have a time domain reference point.

  • Page 274: Using Spectral Analyzer Windows

    Impulse Response Testing: When performing impulse response testing of a system, place the impulse at the zero-phase reference position of the acquisition. This produces a correct phase display. Because the Tek Exponential window has its zero phase reference position at the 20% point, more of the impulse response is captured.

  • Page 276: Gaussian Window

    Nearest Side Lobe: This is the difference in magnitude between the spectral lobe peak in the spectrum and the next side lobe that occurs due to energy leakage. Different windows have different leakage characteristics. The more narrow the resolution bandwidth of the window the more leakage in the spectrum.

  • Page 277: Rectangular Window

    Rectangular Window This window is equal to unity (see the figure below). This means the data samples in the gate are not modified before input to the spectral analyzer. This window has the narrowest resolution bandwidth of any of the windows, but it also has the most spectral leakage and the highest side lobes.

  • Page 278: Hamming Window

    Hamming Window This window is unique in that the time domain shape does not taper all the way to zero at the ends. This makes it a good choice if you wanted to process the real and imaginary parts of the spectrum off line and inverse transform it back to the time domain.

  • Page 279: Hanning, Kaiser-Bessel, And Blackman-Harris Windows

    Hanning, Kaiser-Bessel, and Blackman-Harris Windows These windows have various resolution bandwidths and scallop losses (see the figures below). Choose the one that best allows you to view the signal characteristics you are interested in. The Blackman-Harris has a low amount of energy leakage compared to the other windows. The Hanning has the narrowest resolution bandwidth, but higher side lobes.

  • Page 281: Flattop2 Window

    Flattop2 Window This window has the lowest scallop loss of any of the windows. It also has a wider resolution bandwidth but lower side lobe attenuation. Also, it is unique because the time domain shape has negative values. The Flattop2 window is useful for high accuracy magnitude measurements for signals that do not require very narrow bandwidth.

  • Page 282: Tek Exponential Window

    Tek Exponential Window The Tek Exponential window was invented at Tektronix. In the time domain, it is not a symmetrical bell shape as is the case with the other windows. Instead, it is exponential with a peak at the 20% position of the time domain gate. The frequency domain shape is triangular. Use this window for impulse-response testing where the 20% position is the zero phase reference point.

  • Page 283: Recognizing Aliasing

    Turn on averaging for a math waveform by editing the math expression. Sometimes, it is more desirable to average in the spectrum than in the time domain. For example, consider a signal that has time domain components that are asynchronous to the trigger. If you turn on averaging in the time domain, these components may go to zero or produce strange, nondeterministic effects on the resultant waveform.

  • Page 284: Mask Key Points

    If a standard listed in this manual is not available on your instrument, it is because the configuration or bandwidth of your instrument cannot test that standard. Although the TDS5000B Series instruments are not calibrated optical reference receivers, you can use them with mask testing to evaluate general optical signal characteristics and wave shape, using an external O/E converter.

  • Page 285: Levels Used In Taking Eye Measurements

    Only one mask standard is active at any one time. If you have one mask selected or enabled and then select a new mask, the new mask replaces the previous mask. You cannot test to multiple standards simultaneously. Autofit and Persistence Interaction The Autofit function moves the waveform vertically and horizontally in a mask to reduce the number of segment hits within a mask.

    Communication Triggering (Option) Communication (Comm) triggers are one type of trigger. Comm triggers are designed to work with communication masks and standards. When you select a mask to test, it is associated with a specific communication standard. The mask you select determines the comm trigger needed for that standard.

    The following figure represents how the instrument creates the template waveform limit test envelope from user-entered vertical and horizontal division units. Division units are referenced to graticule divisions, where 1 major division contains 1000 millidivisions, or mdivs. The minimum mdiv unit is 20, which equals one screen pixel. When a source waveform is compared with an envelope waveform, each source waveform sample point value is compared to the vertical and horizontal min/max values of the corresponding envelope waveform sample point.

  • Page 289: Saving And Recalling Waveforms

    Recalling a setup replaces the current setup with the recalled setup. If you do not want to lose your current setup, save the setup file for later recall. Saved setups may contain settings inappropriate for waveforms currently in your instrument. For example, if you save a setup that displays a math waveform that is the average of reference waveform 1, when you recall the setup, if the reference is empty, the math and reference waveforms are not displayed.

  • Page 291: Spectral Analysis Overview

    Spectral Analysis Overview You can use math waveforms to perform FFT (Fast Fourier Transform) measurements with the instrument. The FFT process mathematically converts the standard time-domain signal (repetitive or single-shot acquisition) into its frequency components, providing spectral analysis capabilities. The ability to quickly look at a signal’s frequency components and spectrum shape is a powerful research and analysis tool.

  • Page 292: The Fft Display

    The FFT Display The following illustration shows a typical time-domain waveform and the frequency components of that signal as part of the math FFT waveform. FFT Windows The FFT process assumes that the part of the waveform record used for FFT analysis represents a repeating waveform that starts and ends at or near the same voltage of a cycle.

  • Page 293: Fft Window Characteristics

    transitions between the start and end points cause discontinuities in the waveform that introduce high- frequency transients. These transients add false frequency information to the frequency domain record. Applying a window function to the waveform record changes the waveform so that the start and stop values are close to each other, reducing the discontinuities.

  • Page 294: Time Domain Gating

    Time Domain Gating You can use time domain gating to select a specific segment of your signal for spectral analysis. Two controls, gate position and gate duration, determine the location and size of the gate. The resulting spectrum corresponds to the frequency components of the signal in the gated segment. Time domain gating is inversely proportional to the resolution bandwidth of the spectral waveform.

  • Page 295: Eliminating Aliasing

    Eliminating Aliasing Use the following methods to eliminate aliases: Increase the sample rate by adjusting the horizontal scale to a faster time-per-division setting. Since you increase the Nyquist frequency as you increase the time per division, the aliased frequency components should appear at their proper frequency. If the increased number of frequency components shown on the screen makes it difficult to measure individual components, use MultiView Zoom to magnify the FFT waveform.
