Precise measurements to be referenced to a working standard.
Use the working standard as the LOAD reference DUT and
perform the OPEN/SHORT/LOAD correction.
Measurements using a test xture that has complicated imp edance
characteristics.
In this case, use the OPEN/SHORT/LOAD correction. When
you combine a scanner, the HP 4284A with Option 301 scanner
interface provides p owerful error correction functions for up to
three sets of OPEN/SHORT/LOAD correction data for 128
channels.
