AM Depth
Pressing this softkey enters the value of AM depth. The
active entry area displays the current value of AM depth.
The AM Depth ranges from 0 % to 100 %, with minimum
increment of 0.1 %.
• Default value: 0.0 %
• Key sequence:
AM Source
Pressing this softkey reveals a menu of choices for amplitude
modulation sources. It allows you to select an internal
source or an external source from MOD IN connector, or
select internal and external simultaneously.
Pressing INT connects an internally calibrated signal to the
modulator. This internal AM source defaults to a sine wave
at a frequency of 1.0000 kHz.
Pressing EXT connects an externally calibrated signal to the
modulator. You need also set the EXT Coupling, see
Coupling"
Pressing INT+EXT connects both an internally calibrated
signal and an externally calibrated signal to the modulator
simultaneously.
• Default value: INT
• Key sequence:
AM Rate
Pressing this softkey modifies the internal modulation
frequency. The active entry area displays the current value
of AM rate. The allowed value range is 20 Hz to 80 kHz. The
minimum increment is 0.1 Hz. when external AM source is
selected, this softkey is disabled.
• Default value: 1 kHz
