Unlike the Apply commands, the Output commands are low level
commands to program the function generator.
This section describes the low-level commands used to program the
function generator. Although the APPLy command provides the
most straightforward method to program the function generator, the
low-level commands give you more flexibility to change individual
parameters.
The FUNCtion command selects and outputs the
selected output. The User parameter outputs an
arbitrary waveform previously set by the
SOURce[1|2|3|3RF]:FUNC:USER command.
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.
