Frequently Asked Questions
Can I perform a 4-port TRL calibration?
-- Yes, simply follow the same steps covered in this presentation
Is TRL calibration limited to only 2 ports?
-- No, it can be used with 3- or 4-port calibrations as well
Can I perform a 4-port TRL calibration on-wafer? -- Yes
Since the 4-port 20 GHz PNA-L has only one reference receiver, do I
need a hardware upgrade before I can perform a TRL calibration?
-- No, the 2-step calibration process does NOT require any
hardware upgrade, but may require a firmware upgrade
Since the 4-port 20 GHz PNA-L has only one reference receiver, does
this mean we can only do TRL*?
-- No, the 2-step cal process provides true TRL calibration

TRL Summary
TRL – first characterize the
match differences with delta
match cal and then use them
during TRL calibration
4-port 20 GHz PNA-L with one
reference receiver (switch occurs
after the incident wave detector)
TRL* – ignore “switch
correction” terms
Legacy 872x family with one
reference receiver (switch occurs
after the incident wave detector)
TRL – directly measure
“switch correction” terms
PNA’s & 2-port PNA-L’s with
dedicated two reference receivers
(incident wave detectors occur
after the switch)
