I think you have a bad RAM chip.

Subject: [TekScopes] 2445A Calibration question

I am getting a Test 04 Fail 01 error on a 2445A scope and I have been through the cal proceedure four times. I keep getting the error but when I exit out of the self test, every thing works fine.

Going through the calibration has no issues, no limit errors, etc. Is there anyway to tell what is causing the fail? The manual says the Fail01 is a parity error with the calibration data. Is there any way to tell where this error is? I know that one can examine the ram contents. Is there anything that clues on into what the data should be?
