Chroma 63204A USB triggered digitizing

[Polimistud]

I'm trying to control through LabView a Load Chroma 63204A, in order to sample a sinusoidal response from a device.

However I've had some problems with the digitizing function, both through Chroma's palette and/or direct commands written to the load itself: everything works just fine, but the digitizing trigger sent through USB connection.

I'm pretty sure that the VI is properly written since in "highlight execution" mode the VI is executed correctly, on the other hand trying to delay the execution of blocks before and after the trigger did not solve the problem.

Anyone knowing how to make the digitizing on a chroma63204A through USB command? Thanks a lot!

Hello Polimistud,

i'm not completely sure i've understood correctly.

The device seems working but you want to send a software trigger for the digitizer (via USB) and you don't know how to do it?

Hi Lamber_86,

     thanks for the reply, you perfectly got the issue. Luckly Chroma has recently updated their driver and provided a working example from which it was possible to solve the problem.
