Note that amplitude measurements on a derivative waveform are
in volts per second, and volt-seconds for an integral waveform
measurement.
Using a Predefined Spectral Math Waveform
The following procedure is an example of setting up the instrument to perform spectral analysis of
a signal. This example uses the probe compensation signal available on the front panel of the
instrument.
Install the test hookup
1.
Connect the probe compensation signal to CH 1 through a
suitable probe.
2.
Press DEFAULT SETUP.
3.
Press AUTOSET.
Display the waveform
4.
From the toolbar, click Vert, and select the Chan 1 tab.
5.
Click Offset, and using the multipurpose knobs or keypad,
set the offset to 900 mV and the Ch1 Scale to 200 mV.
Display the spectral math
waveform
6.
From the toolbar, click Math, and select the Math 1 tab.
7.
Click the Predefined Mag button.
The instrument sets up a predefined magnitude spectral analysis
waveform. Your waveform should be similar to the one below.
Display the spectral math
waveform (cont.)
8.
Click the Spectral Analysis Setup button.
9.
Use the multipurpose knobs or keypad to set the frequency
span to 125 kHz and the center frequency to 62.5 kHz (if
necessary, reduce the sample rate).
Setup the Cursors
10.
From the toolbar, click Cursors.
11.
To assign the cursors to the spectral analysis math
waveform, select Math 1 from the list Source list for Cursor
1.
12.
Use the multipurpose knobs or keypad to set the Curs1 Pos
