NI-FGEN to trig NI-DMM

[Funding]

Hi

I have to stimulate a circuit with a 200Hz square signal (NI-PXI5421 waveform generator), but only with 3 periods, after that I have to wait a little and then repeat it a couple of times. The task is to measure the response of the circuit with a NI-PXI4070 DMM, but I can’t figure out how to synchronies the two devices, so that I measure when the 3 pulse are applied. It seams as a standard operation but it is not working for me, is there anybody that has a suggestion to solve my problem??

Thanks

Hi Funding

This is indeed possible by using NI-TCLK. There is an example showing this but its using NI-SCOPE instead of NI-DMM. Using the Scope is more appropriate but as I said its possible to use the DMM's too. The example is shown here. This example is based on two examples installed with LabVIEW when NI-FGEN and NI-Scope was installed. You would have to find the NI-Scope example and see what changes that are implemented. You should find an appropriate example from NI-DMM and implement that in the above given example. I would recommend you look at the examples doing continuous acquisition either in the triggers or multi-point measurements folder.
