FM
FM Stop Rate
Use this softkey to change the ending internal modulation frequency for
swept-sine frequency modulation. To change the value, press the softkey once.
The current value for the FM 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
FM Tone 2 Rate softkey in the FM Dual-Sine Menu.
Any value set for
FM Stop Rate is reflected in the FM Tone 2 Rate softkey.
Conversely, if you change the value for the
FM Tone 2 Rate softkey, the value for
FM Stop Rate is changed to match.

FM Sweep Time
Press this softkey to set the sweep time for swept-sine frequency modulation. The
signal generator will vary the FM 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.
