-221 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)
-221 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.
-221 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.
-221 Settings conflict;
offset changed due to amplitude
The relationship between offset voltage and
output amplitude is shown
below. Vmax is the maximum peak voltage for the selected output
termination (5 volts for a 50Ω load or 10 volts for a high-impedance load).
If the existing offset voltage is not valid, the function generator will
automatically adjust it to the maximum dc voltage allowed with the
amplitude specified.
