I was doing a calibration of a KAT2 I just built and had a significant
error to adjust for Forward power (displayed power was ~30% of
measured). When I looked closely at the DL1 I noticed the trace to the
detector comes from the center of the 50 ohm load. That means the
detected voltage is across 1/2 the load (25 ohms) and changes the power
calc to V^2/25 = P vs. of V^2/50 = P. Can someone confirm this?
Thanks...
