One-Port Reflection Error-Correction

H removes directivity errors of the test setup

nremoves source match errors of the test setup w removes frequency response of the test setup

You can perform a l-port correction for either an S11 or an S22 measurement. The only difference between the two procedures is the measurement parameter that you select.

Note

This is the recommended error-correction process for all reflection

 

measurements, when full two-port correction is not used.

1.Press w).

2.Select the type of measurement you want to make.

qIf you want to make a reflection measurement on PORT 1 (in the forward direction, &), leave the instrument default setting.

7. Connect a shielded open circuit to PORT 1 (or PORT 2 for an SZZ measurement).

 

 

Note

Include any adapters that you will have in the device measurement. That is,

 

connect the calibration standard to the particular connector where you will

 

connect your device under test.
