Page 65: Basic Operations
About Tektronix oscilloscopes Basic operations Preventing ESD. A direct electrostatic discharge can damage the instrument input. To learn how to avoid this damage, read the following information. Electrostatic discharge (ESD) is a concern when handling any electronic equipment. The instrument is designed with robust ESD protection, however it is still possible that large discharges of static electricity directly into the signal input may damage the instrument. - Page 66 About Tektronix oscilloscopes A cable that is left unconnected on a bench, or carried across a room, can develop a large static charge. Discharge the static voltage from all cables before connecting them to the instrument or device under test by momentarily grounding the center conductor of the cable, or by connecting a 50 Ω...

Page 94: Waveform Operations
About Tektronix oscilloscopes Waveform operations Triggering timebase and horizontal delay. The architecture of an analog oscilloscope requires its time bases and triggering to be linked. The main trigger triggers the main time base, and then you can use a delayed trigger to trigger a delayed time base. - Page 95 About Tektronix oscilloscopes Looking at waveform details. Use the instrument Zoom function to magnify an acquisition vertically, horizontally, or in both dimensions to let you see the fine detail in your signals. The MultiView Zoom function affects only the display, not the actual waveform that is being acquired.
- Page 96 About Tektronix oscilloscopes The trigger event can be simple or complex. Examples of a simple trigger are the rising edge of the Channel 1 signal or a glitch narrower than 10 ns on Channel 2. You can set up a complex trigger where the trigger system is armed by a condition on one channel and then is triggered by a condition on another channel.
- Page 97 About Tektronix oscilloscopes Using fast acquisition and DPO. When you turn on FastAcq, you can acquire up to 250,000 waveforms per second. In fast acquisition mode, the dead time between acquisitions can be very short, approaching that of the finest analog oscilloscopes.
- Page 98 About Tektronix oscilloscopes Using logic waveforms. This online help supports many oscilloscope models from Tektronix. This feature is only available on some models. The instrument can display logic waveforms of analog or digital signals in bus views with bus decoding. You can use digital, analog, and math waveforms to define up to 16 buses (serial or parallel) in the Bus Setup window.

Math setups Using spectral analysis 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. -
Page 288: The Fft Display
Math setups Nyquist frequency The highest frequency that any digital oscilloscope can measure without errors is one-half of the sample rate or frequency. This frequency is called the Nyquist frequency. The FFT waveform displays the input signal frequency components from DC (0 Hz) to the Nyquist frequency. ■... -
Page 289: Fft Windows
Math setups 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. In other words, it is an integer number of cycles. When a waveform starts and ends at the same amplitude, there are no artificial discontinuities in the signal shape, and both the frequency and amplitude information is accurate. -

Math setups FFT window characteristics Each FFT window is a trade-off between frequency resolution and magnitude accuracy. What you want to measure and your source signal characteristics help determine which window to use. Use the following guidelines to select the best window.

Page 291: Aliasing
Math setups Aliasing Problems occur when the instrument acquires a signal containing frequency components that are higher in frequency than the Nyquist frequency. The frequency components that are above the Nyquist frequency are under sampled and appear to "fold back" around the Nyquist frequency, showing as lower frequency components. These incorrect components are called aliases. To quickly check for aliasing, slowly decrease the horizontal time scale. -

Page 867: Trigger Holdoff (Random)
Oscilloscope reference After a trigger event, the instrument will not accept another trigger event until after the holdoff value is exceeded. Holdoff is usually specified in units of time, but other units may be used. Trigger holdoff (Random) When Trigger Holdoff is set to Random, the instrument delays the trigger a random amount of time between triggers. This means that successive acquisitions are unrelated to the previous trigger signal. -

Page 875: Set The Vertical Scale
Oscilloscope reference Behavior. The Position control moves the vertical position of the waveform 0.2 divisions (0.02 divisions with FINE control). Increasing the position value moves the waveform up, and decreasing the position value moves the waveform down. The Position control differs from the Offset control; for information on the Offset control for channel waveforms refer to the Vertical Offset Control Window. -
Page 876: Select The Bandwidth
Oscilloscope reference Behavior. Each waveform has its own vertical scale parameter. For a signal with constant amplitude, increasing the scale causes the waveform to appear smaller. Decreasing the scale causes the waveform to appear larger. The scale affects all waveforms, but affects channel waveforms differently: For channel waveforms, the scale setting controls the vertical size of the acquisition window as well as the display scale. -
Page 877: Bus Pattern Condition
Oscilloscope reference Behavior. Bandwidth refers to the range of frequencies the instrument can acquire and display accurately with less than 3 dB attenuation. Each input channel has its own bandwidth selection. To take accurate measurements, the input frequency should be much less than the rated bandwidth of the instrument. A good rule to follow is to ensure the bandwidth of the instrument system is three to five times the bandwidth of the signal that you want to measure. -

Page 891: Set The Vertical Position-Scale
Oscilloscope reference Behavior. Use the Offset control to eliminate clipping the waveform. The offset control affects the vertical acquisition window by subtracting a DC bias from the waveform. This moves the level at the vertical center of the acquisition window of the selected channel. - Page 892 Oscilloscope reference Behavior. Each waveform has its own vertical Position control. The control increases or decreases the vertical position of the waveform 0.2 divisions (0.02 divisions using the Fine knob). Increasing the position value of the waveform moves the waveform up, and decreasing the position moves the waveform down.
