RIGOL DG1032Z PID control

[qhaliakbar]

 I set up the rigol in labview and it's working fine. However I need to modify the program. The idea is to supply the voltage from RIGOL to a heater (of course it involves V-I converter) at 800 kHz and implement a PID control to control the temperature. I can't get my head around how to approach this problem. (You can guess I'm a bit beginner in the labview). General Program VI is attached here.

I was able to implement PID control with NI-DAQ but it can't output high frequencies. Any help will be highly appreciated.

If you want to control the temperature of a heater with an 800 kHz signal input, the primary parameter for PID control might be to regulate the signal's duty cycle rather than its amplitude. This is because at high frequencies, adjusting the amplitude may not be as flexible, while modifying the duty cycle can better achieve temperature control.

You mentioned that you previously implemented PID control using NI-DAQ, did it solely involve adjusting the amplitude to modulate the heater temperature?

Will you specify the heater?
