Adding instrument drift data to table

[Michael Smith]

After characterizing VNA drift, how is that data then entered into the drift table in the database? Same applies for cable and linearity data. I followed the process from the VNA Tools training to perform the characterization, but not sure what the final step is. Searched here and found an old Matlab script, but unable to get that to work.

thank you,

Michael

Hi,

see the VNA Guide, Appendix G.3 

https://www.euramet.org/Media/news/I-CAL-GUI-012_Calibration_Guide_No._12.web.pdf 

Calculate the maximum deviation. 

Define a reasonable envelope that encloses the maximum deviation over the 24 hour time span.

So we do that by hand.

Michael
