Reply To: Store 20dB Pad and how to add Pre-amp

Thanks Justin,
I got it.
About 1, what if executing “store thru” attaching 20dB attenuator and execute “store 20dB pad” with no connection change? Just to be made a calibration as S21 is 0dB including 20dB attenuator but both high and low gain are still ensured?

Best Regards,
