Calibration Types

TRL (TRM) 2-Port The 1.0 mm calibration kit does not include a precision transmission line;

therefore a TRM (Thru-Reﬂect-Match) calibration must be used in place of

the TRL (Thru-Reﬂect-Line) calibration indicated by the menu title.

NOTE The 1.0 mm calibration kit only supports TRM 2-port calibration for

measurement up to 50 GHz.

For this calibration, select:

[CAL] {CAL1 or CAL2} {TRL 2-PORT}
