8-7-1. SOURce[1|2]:FUNCtion
Set
Query
Description
The FUNCtion command selects and outputs the selected output.
The User parameter outputs an arbitrary waveform previously set
by the SOURce[1|2]:FUNC:USER command.
Note
If the function mode is changed and the current frequency setting
is not supported by the new mode, the frequency setting will be
altered to next highest value.
Vpp and Vrms or dBm amplitude values may have different
maximum values due to differences such as crest factor. For
example, if a 5Vrms square wave is changed to a sinewave, then
the Vrms is automatically adjusted to 3.536.
The modulation, burst and sweep modes can only be used with
some of the basic waveforms. If a mode is not supported, the
conflicting mode will be disabled. See the table below.
