PNA software A.06.03

requires by SMC on DUT: both connectors :3.5mm(f) calkit 85052D

1.step :powermeter to port 1
2.opne-(f) on port1
3.short-f...
4.load-f...
5.open-(f) on port 2
6.short-f...
7.load-f...

8.thru female-female between port 1 and port 2
9.thru female-female between port 1 and port 2  :?:

If I compare the achieved S11 or S22 (magnitude and phase) with common (no FCA) measurement the results are not the same.

Why does PNA requires by 8. and 9.steps the same standard or I do something wrong?


But If I perform the SMC with port 1:to DUT 3.5mm-(f);
port 2: to DUT 3.5mm-(m) PNA requieres only 8 steps and result is agree with usual S-measurement.

I’ll appreciate you help.
