Synchronization Frequence Generator with M-Series on PXI

[Kleisi]

Hi everyone,

I'm new to this forum, so please forgive me any mistake.

The system I'm working on consists of a PXI-5401 and a PXI-6070E in a PXI-1036 chassis. It is controlled by a Host PC and the MXI card PXI-8330.

My objective is a generation of frequencies in a defined range and simultaneously acquiring this signal (after it went through a test object) with the M-series card. The problem here is the synchronization. The PXI-5401 is not supported by the DAQmx driver, instead it is controlled with the NI-FGEN driver and I couldn't find any examples therefore.

Has anyone an idea how to do it via the PXI backplane? (no extern cabling)

Kind regards in advance,

Kleisi

Hi again,

I've done a little bit more testing and managed to route the Start Trigger signal from the PXI-5401 to the PXI-6070E:

With a "FGEN Export Signal" VI I exported the "Start Trigger" signal to PXI Trigger Line 0. With a "DAQmx Start Trigger (Digital Edge).vi" I set the source to PXI Trigger Line 1 and it worked. The FGEN task (Master) is started after the DAQmx task (Slave).

I tried to export the "Sync out" signal to PXI Trigger Line 0

and then wired it to the "DAQmx Timing (Sample Clock).vi" as source:

But I get an error (-200284), which says "Some or all of the samples requested have not yet been acquired.".

The "FGEN Export Signal.vi" can export on my PXI-5401 the following signals:

Start Trigger

Synchronization Pulse (tried it too)

Sync out

(and maybe Sample Clock Timebase, but here I get an error (-1074118653 ) at the Export Signal.vi which says "The RTSI or PFI signal/line cannot be connected as specified.")

Someone got an idea how the synchronization could be accomplished?

Kind regards,

Kleisi
