Hi,
I am trying to build a dynamic multitone analog signal generator, which allows dynamic changes of at least amplitude and phase (I withdrew allready from dynamic frequency changes). The hardware is a pxi-4461 and I use the onborad clock for timing. So far it works with the "no regeneration" property and the wait mode set to "Poll". Depending on the chosen frequency I frequently encounter buffer problems. And due to the restrictions of the sample rate and number of samples fore multitone signals, it seems almost impossible to generate signals with a fundamental frequency above 1000 Hz. Which on the other hand is possible with the regeneration property on (no dynamic changes possible). Are there any settings that would improve the behaviour of my generator?
