Calibrations Procedures

 

Transfer function calibrations

Purpose and Procedure

The signal path for the Type C Tx tests always includes additional cables 

and switch relays, that differ from the defined setup of the pure standard 

tests. Because of this, additional calibrations are required.

The 

Check Transfer function 

procedures are meant to verify the right 

location of the transfer functions. They don't calculate or measure any 

S-parameter or transfer functions.

There is a separated calibration for each signal path as shown in 

Figure 16

Transfer function calibrations

Parameters

Most calibration and test procedures as well as the groups containing 

them, have parameters that control the details of how the procedures are 

run. First, select a specific calibration or test procedure or one of the 

groups containing in the N5990A procedure tree. The parameters are 

displayed in a property list on the right side of the screen. If they are not 

displayed, click the 

Properties

 button. Depending on the user selection on 

the left side of the top of the list, the list is either ordered alphabetically or 

in categories.
