And I have a result of +0
Hardware needed:
-ROM 8665B
-Added 0-3 and 3-6 RF switch (note 8664A ROM will flip it to the 3 to 6GHz, output OFF)
-MWEXT 8665B
-Bypass rev protection or find the small 8665B rev power protection of the 6GHz (may loose 3dB)
-U32 IO board matching the attenuator
Calibration steps:
-MW Loop adj
-HF driver adjust
-Run the Recal GPIB software
-Recal Special 171
-Clear memory repeat and fix errors until Result +0
Next upgrade, Pulse option... and add the Circulator (Isolator for Pulse option)
Rewrite my Calibration code to use the power meter instead of just calculate on the inner tables...
