TClk Synchronization Error -250032

[DParrish]

Hi there,

I am currently attempting to create a piece of software that will simultaneously broadcast an arbitrary waveform form one of my AWG's [PXIe-5423] and begin data collection on my oscilloscope [PXIe-5170R - 8 channels].  It needs to happen that the oscilloscope will be triggered by an 'Analogue Edge Ref Trigger' which then triggers the transmission and recording on the cards.

I have attempted to do this using the NI TClk system,  where I should pass the instrument session ID's to the Tclk VI's,  but when using probe mode, I can verify that the instrument ID's  [0x0D2D1AF8,0x0D2D1048] are in the array that is passed to the 'configure for Homogeneous triggers VI'.  Unfortunately, it provides an error -250032  - "The specified session is invalid.  Make sure that the sessions you pass to NI-Clk are valid. Session Index (starts at zero): 1"

This is my first time using this module of code,  and all I needed was the oscilloscope and AWG to be phase-locked so that it broadcasts the waveform for the same number of data points that the oscilloscope records for.  I have not found a way to have the AWG transmit in a finite configuration.  There is an express VI for NI FGen but it does not recognise my AWG's.  

I should mention that I have my program working where it is just the oscilloscope card, so it will wait until the trigger is tripped, and then records the right amount of data from the 8 channels on the card.  I am mainly having these issues where I am trying to integrate the transmission code in now.  I have proven that the AWG's do work using other VI's and all self-tests in MAX came back with no issues. 

I have attached my LabView programs,  which have been made using LabView 2015 SP1, NI-FGen (latest) and NI-Scope (latest).  One of them is my current problem program,  and the other is my working recorded software that uses just the oscilloscope.

I would deeply appreciate any advice at this time.  Many Thanks, Dan.

Hi Dan,

Have you seen the below information on using the Tclk?

It includes lost of useful information on using the TClk system.

Kind Regards,
