Using the Scope and Meter

Acquiring Waveforms

ENTER

Jump to Waveform: and select

Mathematics... to open the

Mathematics menu.

ENTER

Select Function: Spectrum.

ENTER

Select the source waveform for the

spectrum: Source : A, B, C or D

ENTER

Select Window: Auto (automatic

windowing), Hanning, Hamming,

or None (no windowing).

You will see a screen that looks like Figure 11.

Observe that the top right of the screen displays

SPECTRUM.

If it displays LOW AMPL a spectrum measurement cannot

be done as the waveform amplitude is too low.

If it displays WRONG TB the time base setting does not

enable the test tool to display an FFT result. It is either too

slow, which can result in aliasing, or too fast, which results

in less than one signal period on the screen.

Perform a spectrum analysis on

trace A, B, C or D.

Set the horizontal amplitude scale

to linear or logarithmic.

Set the vertical amplitude scale to

linear or logarithmic.

Turn the spectrum function off/on

(toggle function).
