NI PXIe 4141 Source and Measure Trigger issue

[Elamaran]

Hi all,

Please share your comments if you are aware of this problem.

What I have

I am using NI Pxie 4141 SMU for voltage sequence generation.

Short description of what I want

I have to start my Sourcing(start of sequence) and measurement using different edges of a digital pulse.

The expected order of events is as shown below,

(1)Falling Edge(Measurement Trigger) -> (2)Measurement Starts -> (3)Rising Edge(Start Trigger) -> (4)Sequence Starts

I am having trouble in getting the measurement as expected. Please go through the further to get a detailed idea.

Triggers:

1. Measurement Trigger - Measurement should start at the falling edge (which happens first)
2. Start Trigger - Sequence should be produced at the rising edge (which happens second) of the same signal 

Routing: 

Since I cannot configure same Trigger input (I tried) for Source and Measurement, I am Exporting my Start Trigger to one of the PXI Trig channel (/SMU/PXI_Trig0). 

Problem:

Sourcing happens as expected (verified using Scope) but though I get Measurement trigger (falling edge) prior to Sourcing Trigger (rising Edge), Measurement is triggered at only rising edge (which is the Start Trigger edge).

My Guess:

I understood that if Start Trigger is configured both Source & Measure will happen upon the Start Trigger even though we configure Measurement Trigger separately. 

When I tried to use Source Trigger instead of Start Trigger my sequencing is not produced properly. Only one voltage step is produced.

Please share your suggestions.
