Settings conflict;
PWM deviation decreased due to pulse parameters
The PWM deviation is limited by the pulse width or duty cycle, edge time, and
period. The PWM deviation (width or duty cycle deviation) is adjusted to fit within
these limits. See Pulse Width Modulation (PWM) Commands in Chapter 4 for
further information.

Settings conflict;
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 6 MHz, the function generator
will automatically
adjust the duty cycle to 60% (upper limit for this frequency).
Duty Cycle: 20% to 80% (to 5 MHz)
40% to 60% (to 10 MHz)

Settings conflict;
marker forced into sweep span
The marker must be within the sweep span, between the start and stop frequency.
The marker frequency is forced into that range.

Settings conflict;
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.
