Thanks for your help in Source / Receiver CAL, where the Power meter cannot be directly connected to the REF ports.
Here are my questions.
1) on-wafer source power CAL
1-a) Recommended to do Source Power CAL @ 0 dBm (@ coaxial REF, Power meter), first.
Is this still better, instead of using the Calibration Input Power?
I have 3 different Input Powers used for 2-port CAL later.
1-b) On-wafer source power CAL
I build the power table with Power loss @ Coax REF + RF probe loss.
Then, intend to do Source Power CAL at Probe Tip in the air, using the defined power table.
The same question as in 1-a). Should I used 0 dBm during Source power CAL?
2) on-wafer receiver CAL
My on-wafer THRU is a long, angled THRU.
The "offset loss" in the receiver CAL interface is only a single number?
If the THRU loss is relatively large, and freq. dependent, how can I specify the offset loss?
Or is there any better way to do this?
3) 2-port (S-parameter) Calibration with various input power
Instead of doing 3 separate 2-port CALs, can I get this in one step?
The freq. ranges & IFBW are the same for all, except for the input power.
Thanks for your help in advance.
