Standard Types

Load/Short Standards These standards are used to measure reﬂection for:

• S11 1-Port calibrations

• S22 1-Port calibrations

• One-Path 2-Port calibrations

• Full 2-Port calibrations

When you perform any of these calibrations using a 1.0 mm calibration kit,

you will see the following menu:

Notes on the Standards {50GHz LOAD} Refers to either of two 50 GHz loads (with male and

female connectors, as appropriate). This standard is used

for frequencies up to 50 GHz.

{(F) SHORT4} Refers to Short No. 4 with a male connector (that is, the

short is to be connected to a female port). This standard is

used for frequencies from 50 to 75 GHz.

{(F) SHORT2} Refers to Short No. 2 with a male connector (that is, the

short is to be connected to a female port). This standard is

used for frequencies above 75 GHz.

{(M) SHORT4} Refers to Short No. 4 with a female connector (that is, the

open is to be connected to a male port). This standard is

used for frequencies from 50 to 75 GHz.

{(M) SHORT2} Refers to Short No. 2 with a female connector (that is, the

short is to be connected to a male port). This standard is

used for frequencies above 75 GHz.
