• Function Limitations: If you change to a function whose maximum
frequency is less than that of the current function, the frequency is
adjusted to the maximum value for the new function. For example,
if you are currently outputting an 80 MHz sine wave and then change
to the ramp function, the function generator will automatically
adjust
the output frequency to 1 MHz (the upper limit for ramps).
From the
remote
interface, a “Settings conflict” error will be generated and the
frequency
will be adjusted as described.
• Amplitude Limitations: If you change to a function whose maximum
amplitude is less than that of the current function, the amplitude is
automatically adjusted to the maximum value for the new function.
This may occur when the output 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 (the upper
limit for sine in Vrms). From the remote interface, a “Settings conflict”
error will be generated and the amplitude will be adjusted as described.
