Display the
waveform
4. From the button bar, touch Vert, and select the
Chan 1 tab.
5. Touch Offset, and using the multipurpose knobs or
keypad, set the offset to 900 mV and the Ch1 Scale to
200 mV.

waveform
6. From the button bar, touch Math, and select the
Math1tab.
7. Touch the Predefined Mag button.
The instrument sets up a predefined magnitude spectral
analysis waveform.
8. To see the settings, touch the Spectral Analysis Setup
button.
HScale sets the vertical scale factor and lets you set
the vertical scale.
HReference sets the value at the top of the display,
and offset sets the waveform position with respect
to its ground reference.
HRec Length sets the number of samples in the
waveform acquisition.
HSample rate sets the sample rate.
HDuration sets the time over the acquired waveform
(also changes record length).
HResolution controls sample rate and record length
to keep the duration constant while changing the
time between samples of the acquired waveform.
