It's a NI card. But Keithley devices.
2460 Source meter is working flawlessly: write and read and query works well.
I am having trouble with 2420 Source meter and SR844 Lockin. I can write and configure the instruments but the read and query time out. I have no idea why this is 😕
Any suggestions how to resolve this issue?
