3.8.6 Peak Frequency Deviation
The peak frequency deviation represents the variation in frequency of the
modulating waveform from the carrier frequency.
Peak frequency deviation Range:
81150A: 1Hz to 120 MHz
81160A: 1 Hz to 250 MHz
The default is 100 Hz.
The carrier frequency must always be greater than or equal to the
deviation. If you attempt to set the deviation to a value greater than
the carrier frequency (with FM enabled), the 81150A / 81160A will
limit the deviation to the maximum value allowed with the present
carrier frequency.
The sum of the carrier frequency and deviation must be less than or
equal to the maximum frequency for the selected function plus 100
kHz. If you attempt to set the deviation to a value that is not valid, the
81150A / 81160A will limit it to the maximum value allowed with the
present carrier frequency.
After enabling FM, press the Frequency Deviation softkey. Then use the
knob or numeric keypad to enter the desired deviation.
