FM deviation cannot exceed carrier
The carrier frequency must always be greater than or equal to the
frequency deviation. If you attempt to set the deviation to a value greater
than the carrier frequency (with FM enabled), the function generator
will automatically adjust the deviation to the maximum value allowed
with the present carrier frequency.

FM deviation exceeds max 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
(80.1 MHz for sine and square, 1.1 MHz for ramp, and 25.1 MHz for
arbitrary waveforms). If you attempt to set the deviation to a value that
is not valid, the function generator will automatically adjust it to the
maximum value allowed with the present carrier frequency.

frequency forced duty cycle change
If the square wave function is selected and you change to a frequency
that cannot produce the current duty cycle, the duty cycle is
automatically adjusted to the maximum value for the new frequency.
For example, if you currently have the duty cycle set to 70% and then
change the frequency to 60 MHz, the function generator will automatically
adjust the duty cycle to 50% (upper limit for this frequency).
Duty Cycle: 20% to 80% (frequency < 25 MHz)

selected arb is missing, changing selection to default
If you delete an arbitrary waveform from non-volatile memory after
storing the instrument state, the waveform data is lost and the function
generator will not output the waveform when the state is recalled.
The built-in "exponential rise" waveform is output in place of the
deleted waveform.
40% to 60% (25 MHz < frequency < 50 MHz)
50% (frequency > 50 MHz)
