Arbitrary Waveform Generator

150

FREQ/CAPTURE Button

This button has two functions:

- Opens the generator menu and places the cursor

on the frequency parameter (Primary function)

- Captures the signal on display and stores it into

internal arbitrary waveform memory (Secondary

function)

When FREQ button is pressed, the generator menu will

automatically open up with the frequency related parameter

highlighted and the cursor placed on the frequency. The

Output Type selected determines which frequency

parameter will be highlighted, e.g. the carrier frequency

parameter if output type is set to AM. When FREQ button is

pressed and held for a few seconds, it will capture the

signal on the display and save the data into internal arbitrary

waveform memory. The signal source of the captured signal

and the location it is stored to depend on the settings

configured under the sub-menu for User ARB Output Type .

Essentially this secondary function works the same as the

Save option under Capture/Storage selection in the

sub-menu for User ARB Output Type . See next section

for details.
