Page 233: Waveform Acquisition
Waveform acquisition Waveform acquisition Acquisition concepts The Acquisition system sets which data points are used to acquire waveforms. Acquisition hardware Before a signal is displayed, it must pass through the input channel where it is scaled and digitized. Each channel has a dedicated input amplifier and digitizer.
Page 234: Interpolation
Waveform acquisition position is 50 percent, then the trigger point is in the middle of the waveform record. When horizontal delay is on, the time from the trigger point to the horizontal reference is the horizontal delay. Interpolation Your instrument can interpolate between the samples it acquires when it does not have all of the actual samples it needs to fill the waveform record.
Page 235: Waveform Sample Interpolation
Waveform acquisition Acquisition mode Envelope mode finds the highest and lowest record points over many acquisitions. Envelope uses Peak Detect for each individual acquisition. Average mode calculates the average value for each record point over many acquisitions. Average uses Sample mode for each individual acquisition.
Page 236: Vertical Acquisition Considerations
Waveform acquisition Set the horizontal scale, position, and resolution (record length) to include the acquired waveform record waveform attributes of interest with good sampling density on the waveform. These settings define the horizontal acquisition window, described in Horizontal acquisition considerations on page 236 .
Page 237: Triggering Concepts
Triggering concepts Triggering concepts User selected trigger conditions are used to capture waveforms for measurement and analysis. The next figure shows how triggers fit into the overall instrument operation. Trigger helps you to capture meaningful waveforms to display on screen. This instrument has simple edge triggers as well as a variety of advanced triggers.
Page 238: Trigger Types
Triggering concepts Trigger types The available trigger types include: Edge: This is the simplest and most commonly used trigger type, used with analog signal. An edge trigger event occurs when the trigger source passes through a specified voltage level in the specified direction (rising or falling signal voltage). When the edge trigger source is set to Internal, the instrument uses an internally generated 60 Hz signal to generate a trigger.
Page 239: Trigger Coupling
Triggering concepts The Holdoff setting range is 0 s (minimum holdoff available) to 10 s (maximum holdoff available). For more information on how to set holdoff, see Set Trigger Holdoff on page 85. Learn about Trigger coupling Learn about Trigger modes Trigger coupling Trigger coupling determines what part of the signal is passed to the trigger circuit.
Page 240: Advanced Triggering
Triggering concepts Advanced triggering You can check the advanced trigger status in the settings bar. The readout indicates the trigger type and then shows sources, levels, or any other parameters that are important for the particular trigger type. Bus triggering concepts A bus trigger occurs when a supported instrument detects a bus pattern that you specify for a parallel bus, or a bus cycle you select for a serial bus.
Page 241: Logic Trigger Concepts
Triggering concepts Logic trigger concepts Trigger the instrument when logic patterns are true. You can set each bit to be active High, Low, or Don't Care. You can also set the logic thresholds and define the logic (AND, OR, NOR, or NAND). Setup and Hold trigger concepts A setup/hold trigger occurs when a data signal changes state inside of the user specified setup and hold times relative to the clock.

Page 243: Measurement Concepts
Measurement concepts Measurement concepts Measurement variables By knowing how the instrument makes calculations, you may better understand how to use your instrument and how to interpret your results. The instrument uses a variety of variables in its calculations. These include: Definition of Base and Top Base is the value used as the 0% level in measurements such as fall time and rise time.
Page 244 Measurement concepts 3. The level with the most points in the upper histogram is the Top value, and the level with the most points in the lower histogram is the Base value. If Mid gives the largest peak value within the histogram, the oscilloscope returns the Mid value for both Top and Base (this is probably a very low amplitude waveform).
Page 245: Missing Or Out-Of-Range Samples
Measurement concepts The instrument calculates these values as follows: 1. Find the first Mid reference edge in the waveform record or the gated region. This is Edge1. 2. Continuing from Edge1, find the next Mid reference edge in the waveform record (or the gated region) of the opposite direction of Edge1.

Page 247: Math Waveform Sources
Measurement concepts Dependencies In general, math waveforms that include sources as operands are affected by updates to those sources: • Shifts in amplitude or DC level of input sources that cause the source to clip also clip the waveform data supplied to the math waveform.
Page 248: Math Waveform Differentiation
Measurement concepts Example: [CoefFileName="highpass_0.25bw.flt"]HighPass(Ch1) CoefFileName is the setting and is used as the high pass filter on channel 1. Example: [CoefFileName="highpass_0.25bw.flt"] HighPass(Ch1) + [CoefFileName="lowpass_0.05bw.flt"] LowPass(Ch2) The high pass filter file is applied to channel 1 and lowpass_0.05bw.flt is applied to channel 2. Functions, except for basic and logic functions, have the syntax function(source).
Page 249: Math Waveform Offset, Position, And Scale
Measurement concepts Math waveform 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).
Page 250: Fft Process
Measurement concepts • You should scale and position the source waveform so that it is contained on screen. (Off screen waveforms may be clipped, which will result in errors in the integral waveform.) • You can use vertical position and vertical offset to position your source waveform. The vertical position and vertical offset will not affect your integral waveform unless you position the source waveform off screen so that it is clipped.
Page 251: Blackman-Harris Fft Window Concepts
Measurement concepts Another way to recognize aliasing is to realize that higher order harmonics usually have decreasing magnitudes compared to lower order harmonics. Thus, if you see a series of increasing harmonic magnitude values as frequency increases then you can suspect that they may be aliased.
Page 252: Flattop2 Window
Measurement concepts 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. Note: The Flattop2 window is useful for high accuracy magnitude measurements for signals that do not require very narrow bandwidth.
Page 253: Hanning Fft Window
Measurement concepts Hanning FFT window FFT windows have various resolution bandwidths and scallop losses (see the figure below). Choose the one that best allows you to view the signal characteristics you are interested in. The Hanning window has the narrowest resolution bandwidth, but higher side lobes. Hanning has slightly poorer frequency resolution than Hamming.
Page 254: Kaiser-Bessel Fft Window
Measurement concepts Kaiser-Bessel FFT window A Kaiser-Bessel window balances amplitude accuracy, side lobe distance, and side lobe height. Although similar to the Blackman-Harris window, the near side lobes in a Kaiser- Bessel window tend to be higher for the same main lobe width, while the further-out side lobes are lower.
Page 255: Tek-Exponential Window
Measurement concepts Tek-Exponential window 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. Note: Use this window for impulse-response testing where the 20% position is the zero phase reference point.

Page 258: Positive Overshoot Measurement Algorithm
Measurement algorithms Note that overshoot values should never be negative (unless Top or Base are set out-of-range). Positive Overshoot measurement algorithm Positive Overshoot is the difference between Maximum and Top, divided by the amplitude. It is the percent that the waveform goes above top.
Page 259: Fall Time Measurement Algorithm
Measurement algorithms In the diagram below, the Falling Slew Rate from mid ref to low ref is calculated using the following equation: Falling Slew Rate = (VREF - VREFLO)/ΔTF Fall Time measurement algorithm Fall Time is the time required for an edge to fall from the high reference level to the low reference level. By default the measurement is from reference level 90% amplitude to 10% amplitude.

Measurement algorithms Frequency measurement algorithm Frequency is the reciprocal of the period. Frequency is typically measured in Hertz (Hz) where 1 Hz = 1 cycle per second. Frequency = 1 / Period High Time measurement algorithm High Time is the amount of time that a waveform cycle is above the High reference voltage level. The application calculates the measurement using the following equation: Where: T High is the high time.

Given a voltage waveform, the N-Period is calculated as follows: If the Signal Type is Clock The N–Period measurement calculates the elapsed time for N consecutive crossings of the mid reference voltage level in the direction...
Page 262: Period Measurement Algorithm
Measurement algorithms Period measurement algorithm The time between two adjacent crossings of the Mid reference level (one cycle) of the waveform. Period is measured in horizontal units, typically seconds. Period = Edge3 - Edge1 Phase measurement algorithm Phase is the ratio of the Skew between two sources to the Period of the first source. It is the amount of phase shift between edges of the two waveforms.
Page 263: Rise Time Measurement Algorithm
Measurement algorithms Rise Time measurement algorithm Rise Time is the time required for an edge to rise from the low reference level to the high reference level. By default the measurement is from reference level 10% amplitude to 90% amplitude. The following figure shows a rising edge with the two crossings necessary to calculate a Rise Time measurement.
Page 264: Skew
Measurement algorithms The application calculates this measurement using the following equation: Where: T Setup is the setup time. T Main is the Main input (clock) Mid reference crossing time in the specified direction. T 2nd is the 2nd input (data) Mid2 reference crossing time in the specified direction. Skew Skew is the time between the mid reference level crossing on Source1 to the mid reference level crossing on Source2.
Page 265: Time To Max
Measurement algorithms Time to Max Time to Max is the amount of time from the trigger point to the maximum data point. This measurement can be made across the entire record or on each cycle in the record. Time to Min Time to Min is the amount of time from the trigger point to the minimum data point.
