Hardkey and Softkey Reference
AM
AM Stop Rate
Use this softkey to change the ending internal modulation frequency for
swept-sine amplitude modulation. To change the value, press the softkey once.
The current value for the AM stop rate is displayed in the active entry area. To
enter a new value, rotate the front panel knob until the desired value is displayed,
use the up and down arrow keys, or enter the value using the numeric keypad and
press the
Hz or kHz terminator softkey. The range of values allowed is 0.1 Hz to 50
kHz. The minimum increment allowed is 0.1 Hz.
This softkey is coupled to the
AM Tone 2 Rate softkey in the AM Dual-Sine Menu.
Any value set for
AM Stop Rate is reflected in the AM Tone 2 Rate softkey.
Conversely, if you change the value for the
AM Tone 2 Rate softkey, the value for
AM Stop Rate is changed to match.
Softkey Location: Press
AM, AM Waveform, Swept-Sine, AM Stop Rate
Status after Normal Preset: 400.0 Hz
SCPI Commands:

AM Sweep Time
Press this softkey to set the sweep time for swept-sine amplitude modulation. The
signal generator will vary the AM rate from the specified start rate to the stop rate
in the time set with this softkey. Enter the desired sweep time using the up and
down arrow keys, the front panel knob, or enter a value using the numeric keypad
and press the
sec or msec terminator softkey. The range of values allowed is 1 ms
through 65.535 s. The minimum increment allowed is 1 ms.
Softkey Location: Press
AM, AM Waveform, Swept-Sine, AM Sweep Time
Status after Normal Preset: 100.0 msec
SCPI Commands:
