Output Amplitude
For the amplitude parameter of the APPLy command, the output
amplitude range depends on the function currently selected and the
output termination. You can substitute “
MINimum”, “MAXimum”,
or “
DEFault” in place of a specific value for the amplitude parameter.
MIN selects the smallest amplitude for the selected function (50 mVpp
into 50 ohms).
MAX selects the largest amplitude (10 Vpp into 50 ohms).
The default amplitude is 100 mVpp (into 50 ohms) for all functions.
For arbitrary waveforms, the maximum amplitude will be limited if
the data points do not span the full range of the output
DAC (Digital-
to-Analog Converter). For example, the built-in “
SINC” waveform does
not use the full range of values between
1 and therefore its
maximum amplitude is 6.084 Vpp (into 50 ohms).
You can set the units for output amplitude to Vpp, Vrms, or dBm.
See “Output Units” on page 64 for more information.

There are five built-in arbitrary waveforms stored in non-volatile memory:
sinc, negative ramp, exponential rise, exponential fall, and cardiac.
