FM Tone 1 Rate
Press this softkey to set the internal modulation frequency for the FM tone 1.
Enter the desired rate using the up and down arrow keys, the front panel knob, or
enter a value using the numeric keypad and press the
kHz or Hz terminator softkey.
The range of values allowed is 0.1 Hz through 50 kHz. The minimum increment
allowed is 0.1 Hz.
This softkey is coupled to the
FM Rate softkey in the initial FM Menu and the
FM Start Rate softkey in the FM Swept-Sine Menu. Any value set for
FM Tone 1 Rate is reflected in the FM Rate and FM Start Rate softkeys. Conversely,
if you change the value for either the
FM Rate softkey or the FM Start Rate softkey,
the value for
FM Tone 1 Rate is changed to match.
