AFG3022 Changing amplitude and offset

Post by hithesh123 » August 24th, 2014, 11:55 pm

Is there a way to change amplitude and offset at the same time.
Let's say I need a signal with variable amplitude from 1Vpk-pk to 5Vpk-pk
Offset should change accordingly from 0.5 to 2.5v.
This is for a sine wave.

define "same time". Within a millisecond or a nanosecond?

Same time - within nanoseconds would be great. But I can settle for milliseconds.

you can send concatenated programmatic commands. it takes about 100 ms and the output will have aberrations especially if you are crossing attenuator banks.

Code: Select all

:source1:voltage:offset 1;:source1:voltage 2;
:source1:voltage:offset -1;:source1:voltage 1;
for uncompromising control of your output, you'll need an AWG.
