Calibration of a Logic Analyzer 201-338

[Tom Pyragon]

I have a logic analyzer, 201-338.  We use this for testing which sometimes needs to be reported.  What is the factory recommended calibration interval?  What does a calibration or functional verification cost?  We need this for out QA program.  The unit we have it 3 years old and seems to work just fine.  Is it likely to still be in calibration?

Hi @Tom Pyragon,

I don't believe Digilent has an officially recommended calibration interval for the Digital Discovery. I personally only calibrate my devices when I start to suspect it feels off, which admittedly is more of a gut feel than anything.

As the Digital Discovery is primarily a digital device (no analog inputs/outputs like on most of Digilent's other Test and Measurement Products), the calibration procedure within WaveForms for the Digital Discovery (WaveForms Device Manager -> Calibrate button) correspondly only calibrates the Digital Supply voltage output and the built in Ammeter for the supply.

My personal opinion is that your device is most likely perfectly and in calibration as is, though of course it won't hurt to do a calibration if it is better for your documentation purposes. To be clear, Digilent does not offer any calibration services for our boards.

Let me know if you have any questions.

Thanks,
