Re: Two RigExpert models disagree on stub length?
|
I have used both the AA-600 and the Stick Pro.?? I have never had to calibrate either.
?
I also have the Array Solutions AIM-UHF that requires calibration before you can use it.?
?
I have found that both the Rigexpert models and the calibrated AIM UHF have delivered comparable results.
?
That being said I have not conducted a precise laboratory type test. I just generally know that Rigexpert models have been trustworthy and reliable instruments for what I use it for, which is checking feed line integrity and tuning antennas.

I have been advised that for general use you do not have to calibrate a RigExpert as the factory calibration is good and it is an ¡°average¡± result you will get. ?For specific frequencies and accuracy recalibrate at the frequency of question.
That was the explanation I was given as to why I didn¡¯t have to REcalibrate my RigExpert tools like I do for my NanoVNA. I hope that helps someone.

?When I go to that link, I don't see any firmware. I did run the updater tool a few weeks ago and it updated to 1.119. I'll check again later today.
I must apologise to Alex as when I did do a calibration on both units, the stub is now the same frequency on? both units.
I'm left with the issue of the firmware locking up when cancelling a TDR sweep, but that might change if there is a new firmware available.
The only other item is the SWRtoAIR feature... There is no modulation, just the carrier with at least THIS firmware. Hopefully the newer one works correctly.?
