VSWR

This test measures the VSWR of the input port of the power sensor module with the RF output port terminated with a 50 Ohm load. This test recalls the state saved in the Two Port Network Analyzer Calibration test.  A verification kit or a verification sensor can be used to verify the two port calibration.

Verification Kit Usage

The verification kit can be used instead of a power sensor to verify the network analyzer calibration. The software will only use one item in the verification kit to verify the cal. This item will be the largest fixed attenuator in the kit.

Each verification kit comes with the data needed to verify the network analyzer calibration.  

In order to use the verification kit, save the .unc and .dat file for the largest fixed attenuator to following location depending on the operating system:

Windows 7 and Windows 10: C:ProgramData\Agilent Technologies\Test Management Environment\VerificationKit

For Windows 7 and Windows 10, the VSWR test will create the path above if it is not found. You will have to access the destination folder by copying the compete path to Windows Explorer.

You will need to rename the file by opening the file and copying from the second line everything that follows #Part: This number contains the model number and serial number of the fixed attenuator. When mapping the verification kit in TME, enter the five digit serial number located on the largest fixed attenuator in the kit.

Copy the files to C:ProgramData\Agilent Technologies\Test Management Environment\VerificationKit

Open the file and copy the part number.

Rename the files using the part number.
