Press
Edit Depth
to open the AM Depth parameter,
then edit the current value using the cursor control
keys, rotary data knob, or enter a new value using
the keypad and the appropriate terminator key
(
kHz/
m
s/STEPS
for Linear;
MHz/ms/dB
for Log). The
AM Depth range is 0% to 100% in Linear and
0 dB to 25 dB in Log. To close the open AM Depth
parameter, press
Edit Depth
or make another menu
selection.
Press
Edit Rate
to open the AM Rate parameter,
then edit the current value using the cursor control
keys, rotary data knob, or enter a new value using
the keypad and the appropriate terminator key. The
AM rate range is 0.1 Hz to 1 MHz for sine wave and
0.1 Hz to 100 kHz for square, triangle, and ramp
waveforms. To close the open AM Rate parameter,
press
Edit Rate
or make another menu selection.
