Hi, I have 4 pieces PXIe-4135 installed in PXIe-1092 chassis. I tried ‘nidcpower’ programming example to synchronize all my PXIe-4135 when doing voltage sequence, here are my configurations:
1. Set one of 4 PXIe-4135 as the master channel, and the other 3 to slaves;
2. The slaves would source when they received master's 'source trigger', and do measurements when they received master's 'source complete event';
3. The Master's 'source delay' was set to 10ms, and the slaves' source delay was set to 50us(which is exactly the same as the official programming example and I think such a setting makes sense).
4. All of them are 'auto range';
5. with nothing connected to these PXIe-4135(open measurement).
The current I got(PXIe-4135 measured) is confusing, the current the master channel measured is reasonable, down to 10fA(10e-14) or around, but the current the slaves measured were several hundred nano amperes(10e-7).
Only when I cancel the trigger(not use) or increase the source delay of the slaves to 20ms above, the result could be reasonable.
I have put my code and results on this post, please kindly check it. Thanks.
