    • Reply: soasystem The theme of creating KC901V not showing correct resistance at near DC...

      but capacitor reactance should be infinity at DC right? checking the reactance (Z -> X) at DC, KC901V showing zero. i suspect this has to do with poor directivity of directional coupler (or power splitter?) at DC that FW has to predict starting from 50 ohm and as the freq increase, reading converge to the true value. i hope there is a way to start reading R at DC and hence prediction should start from that DC resistance. 47 days ago
