I put things back together enough to turn it on. what I found this morning was slight different that what I found ( thought I found ) last night.
Frequency is OK. I checked several points and all were good ( Agilent E4432B )
Amplitude seems OK, worst I saw was .6 dBm low. TG trace was not horrible but I don't know what it looked like before. ( pic attached )
Input impedance is still off, the only way I have to gauge this is using one of my transmitters and TX'ing into the SA. Before the over power, I was getting a near perfect SWR, now I get high SWR on all 3 TXs I tried.
When I measure the switches, U1 is different than the others.
I went back and rechecked all the diodes in the path at each stage, all were OK.
I will replace U1 ( maybe all just cause )
Thanks
