-221 Settings conflict; amplitude has been adjusted
The requested output amplitude is not valid. The output amplitude is
automatically adjusted to be compatible with the present configuration.
This error will be generated in the following instances:
The output amplitude is automatically adjusted if you select a
function whose maximum amplitude is less than that of the currently
active function. This conflict may arise when the output units are
Vrms or dBm due to the differences in crest factor.
If the specified amplitude is not valid, the function generator will
automatically adjust it to the maximum value allowed with the present
offset voltage. The output amplitude (in Vpp) and the dc offset voltage
must obey the following restrictions. (Vmax is either 10 volts for a
high impedance termination or 5 volts for a 50 ohm termination.)
-221 Settings conflict; cannot adjust phase in present configuration
Option 001 Phase-Lock Only. The phase cannot be adjusted real-time if
an arbitrary waveform is selected, a modulation mode (other that burst)
is enabled, or if burst is enabled with a burst count other than infinity.
-221 Settings conflict; duty cycle has been adjusted
The requested duty cycle is not valid. For output frequencies above 5 MHz,
the duty cycle is limited to values between 40% and 60% (below 5 MHz,
the range is 20% to 80%). The duty cycle is automatically adjusted if you
select a frequency that is not valid with the present duty cycle percentage.
For example, if you set the duty cycle to 70% and then change the
frequency to 8 MHz, the function generator will automatically adjust the
duty cycle to 60% (the upper limit for this frequency).
-221 Settings conflict; fm deviation has been adjusted
The requested
FM peak frequency deviation is not valid. The sum of the
carrier frequency and peak frequency deviation must be less than or
equal to the maximum frequency for the selected function
plus 100 kHz
(15.1 MHz for sine and square, 200 kHz for triangle and ramp, and
5.1 MHz for arbitrary waveforms). If you attempt to set the deviation to
a value that is not valid, the function generator will automatically
adjust the deviation to the maximum value allowed with the present
carrier frequency.
