Output Commands
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. Even though the APPLy command is the easiest
way to program the function generator, it lacks the ability to change
individual parameters. The Output commands on the other hand
can be used to set individual parameters, or those parameters that
cannot be programmed with the Apply command.
SOURce[1]:FUNCtion
Set
Query
Description The FUNCtion command selects and outputs the
selected output function. The User parameter
outputs an arbitrary waveform previously set by
the SOURce[1]:FUNC:USER command.
The previously set frequency, amplitude and offset
values are used automatically.
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 the
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
value is automatically adjusted to 3.536Vrms.
The modulation 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.
