Hello everyone,,
When attempting to synchronize a 4071 DMM and a 6255 DAQ, The DMM seems to have inconsistant start delay. I have several bits of code that turn on and off voltages and I am attempting to align the rise and fall in current with the rise and fall in voltage. I'm measuring two DAQ channels and comparing that to the DMM. The rise and fall times are on the order to 5ms and the entire on-off plateau takes around 1second. I'm reading at 4000 samples/second.
The first time I run the measurement the DMM start delay appears to always be ~4.75ms (hence the 5ms delay in the code below). After the first run, the delay can be between 4-9ms.
1. Am I setting up the instruments correctly?
2. Is there a better way to do synchronization?
Plzzzz suggest....
