We have a N9925a FieldFox Network Analyzer and calibration result seems to be good while using 1m electric wire (3.5mm port) .I operate like this:
1. Press 'measure' button and change to 's21'
2. 'BW'
3. 'measure set up' --------start Frq 1GHz stop Frq 6GHZ
4.'cal' -------------quickcal
step1 --------measure
step4---------using 85052c kit to connect port 1 to port 2.As we don't have any male-male connector, i have to use TRU kit from 85052C to connect port1 to port2 in progress 4.
5. while examining cal result,i connect OPEN kit (from 85052C ) to port 1,change the measure to s11 ,and check the smith chart.,I expect it to go around the Smith chart. At least it works while we calibrate E5071C. And i hope while connceting to radar antenna, and transforming REAL to time domain, there is just one pulse signal around 0ns.
It works well,when i use 1m wire. While using 6m's, the result is bad.

So i want to use the mechanical cal, but there is't have the option '85052c'. And i tried DataLink to edit a new CalKit, but i can't find the file '85052c.xml'. Is there anyone has experience in this field?
