Calibration Verification

Question asked by SOLT_guy on Jan 19, 2012

Dear Sir:

      I used a 30 cm airline to verify a calibration.     

       After shorting the airline, I saw about 1dB of peak to peak ripple. 

       I wanted to know if there is an algorithm that has been developed which can tell the NA user that his calibration can be improved by changing the cal kit inputs.    In other words, substitute different cal kit inputs into the NA, determine the resulting ripple pattern, and make a decision as to whether changing cal kit inputs are appropriate.

        Also, can you tell me the worst case phase and magnitude error I can expect with a 1 dB peak to peak ripple pattern (assume I have a perfect airline)?

        Thank you for your time and I look forward to reading your reply.
