TTi calibration....
« on: September 28, 2022, 03:29:41 PM »

Well, doing some power measurements the other day troubleshooting some equipment that was out on a gig... I noticed the TTi unit I was using was routinely reading 20dBm lower than expected.


Both my FSH and RFE were reading as expected (13-14dBm for expected 30mW output)


In the Calibrate Hardware program, there are 182 calibration steps...


The manual mentions that Recalibration should be done by skilled personnel ... which leads me to believe that this particular unit never was calibrated before retail..


I do have access to a 0-6GHz Signal Generator.. has anyone performed a calibration on one of these units beforehand?




Thanks,


Brad

I haven't, but I'm curious, which model do you have? I have the PSA3605.
