Reducing Mismatch Errors

Mismatch errors result from differences between the 

 port impedance

and the analyzer’s port impedance. Source match errors are produced on
the source (analyzer RF OUT) side of the DUT; load match errors on the

load (analyzer RF IN) side. If the DUT is not connected directly to the port,
the mismatch errors due to cables, adapters, etc. are considered part of the
source or load match errors. Source match and load match error terms can be
reduced by using the methods described in this section.

 

 

   

 

The best way to reduce mismatch errors in a reflection measurement is to
perform a reflection calibration directly at the DUT connector, using the exact
frequency parameters that you will be using for the measurement.

1. Set up your reflection measurement and frequency parameters.

 

Press [CAL) 

 

 .

3. Follow the instructions on the display.

For more information on calibrations see Chapter 6.
