TRL Calibration with 4-port 20 GHz PNA-L’s
Yes, it can be done! (requires firmware A.05.25 and later)
Is “true” TRL calibration, not an approximation like TRL*
Two-step (two-tier) calibration process:
• Step 1: “Delta Match” calibration
• Step 2: Normal TRL calibration
What is a “Delta Match” cal?
• characterizes the difference (delta) between the source match
and load match of each port of the VNA
• allows a VNA having a single
reference receiver to
perform TRL-style calibrations (including Unknown-Thru)
Why 2 steps?
