I am currently attempting to change the clock rate on a NI-9425. The module manual states that the rate should be 7us, but when I am testing it the rates seems to be locked down to 1kHz that is a far cry from the 140kHz that is defined on the speciifcation sheet. Is there any method to change clock rate without using the FPGA module.

Attached is the code. Thank you for looking.

I hooked up a 9425 and then added a DAQmx property node(attached snippet) to your code, and set the sample clock source as ai/SampleClock. I didn't receive any errors relative to the clock, only an error about acquiring data since I don't have anything connected to the 9425. The Sample clock rate said that the sample clock was 140kHz, so I'm not able to reproduce the error you're receiving.
