Re: TinySA calibration and level check with sma cable or both cables?

 

I believe the TinySA is only measuring signal levels, not phase differences, as the NanoVNA does on calibration. Using two might actually have a negative effect on the calibration. You have the insertion loss of the interface between two pieces of coax and the SMA barrel connector.

What is the proper way to calibrate unit? I see one person uses one sma cable between low and high. Then, I see another person states that the unit comes with 2 cables and a barrel connector, as it is necessary to join 2 cables between low and high. Please advise.
