It happens I have an HP8753c vna and a HP85060c ecal system. Unfortunately the 8753 firmware is version 4.01 and HP85060c wants 4.02 to control the analyzer. Someone knows if a patch exists to overcome this limit, or I have to continue using mechanical calibration with this VNA?
I suspect the data is in EPROM's. You might find someone on the HP/Agilent Yahoo group who has a later version that might be willing to copy them. But I do not know this for certain.
