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

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
