Output Amplitude

As shown below, the output amplitude range depends on the function
currently selected and the output termination. The default amplitude is
100 mVpp (into 50 ohms) for all functions.

1 There are five built-in arbitrary waveforms stored in non-volatile memory:
sinc, negative ramp, exponential rise, exponential fall, and cardiac.
• For arbitrary waveforms, the maximum amplitude will be limited if
the data points do not span the full range of the output
to-Analog Converter). For example, the built-in "
not use the full range of values between
maximum amplitude is 6.084 Vpp (into 50 ohms).
• Possible Conflict with Function Change: 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 for the output functions. For example, if you
output a 5 Vrms square wave (into 50 ohms) and then change the
function to sine wave, the function generator will adjust the output
amplitude to 3.535 Vrms (the upper limit for sine waves in Vrms).

generated and the amplitude is adjusted.
