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.
