-221 Settings conflict;
edge time decreased due to pulse width
For a pulse waveform, the function generator will automatically adjust
the waveform parameters in the following order as needed to generate a
valid pulse: (1) edge time, (2) pulse width, and then (3) period.
In this case, the function generator has decreased the edge time to
accommodate the specified pulse width.
Pulse Width >
1.6 X Edge Time
-221 Settings conflict;
amplitude changed due to function
In some cases, the amplitude limits are determined by the output units
currently selected. This may occur when the units are Vrms or dBm due
to the differences in crest factor for the various output functions.
For example, if you output a 5 Vrms square wave (into 50 ohms) and
then change to the sine wave function, the function generator will
automatically adjust the output amplitude to 3.536 Vrms (upper limit for
sine waves in Vrms).
-221 Settings conflict;
offset changed on exit from dc function
In the dc voltage function, the voltage level is controlled by adjusting the
offset voltage (the current amplitude is ignored). When you select a
different function, the function generator will adjust the offset voltage as
needed to be compatible with the current amplitude setting.
