VSWR

This test measures the Voltage Standing Wave Ratio (VSWR) of the Keysight power sensor. A network analyzer accompanied with a calibration kit or electronic calibration modules is used to perform this test.

For the UUT N848xB power sensors, the network analyzer calibration is done in the Two Port Network Analyzer Calibration test.

Table Footnotes

[1] E9304A Opt H18 uses both ENA and PNA to perform VSWR test. ENA covers 9 kHz to < 10 MHz and PNA covers 10 MHz to 18 GHz frequency range.

[2] The following minimum PNA firmware revisions or above are required to include phase wrapping fix:

[3] Supported N5230A and N5230C options: This calibration application supports any option that covers the entire frequency range of the UUT.

[4] Supported E5071C options: This calibration application supports any option that covers the entire frequency range of the UUT.

[5] D-model ECals can only be used with the following network analyzer models and firmware versions:

[6] Supported power sensor options:

 

 

When connecting the power sensor model N8481B or N8482B to the network analyzer’s test port, please ensure the fixed attenuator is supported by an object or fixture to prevent bending on the adapter or connector. See the picture below for an example of the connection.

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 calibration — this item will be the largest fixed attenuator in the kit.

Each Verification Kit comes with a 3.5 floppy PNA Verification Data Disk or a USB flash disk which contains the data we need 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 this location:

C:\Documents and Settings\All Users\Application Data\Agilent Technologies\Test Management Environment\VerificationKit

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 5 digit serial number located on the largest fixed attenuator in the kit.

Copy the files here:

Open the file and copy the part number:

Rename the files using the part number:

E-Cal Usage

An E-Cal may be used for the Network Analyzer Calibration instead of a mechanical calibration kit. When using the E-Cal, connect it to the network analyzer using a USB cable.  Before using the E-Cal, ensure that the ready light has turned green on the unit.  When mapping the E-Cal in TME, the serial number should be a 5 digit number with no letters.  If there is no five-digit serial number printed on your unit, then follows these instructions using your network analyzer to locate your serial number:

  1. Connect the E-Cal to the network analyzer using a USB cable
  2. Press the Cal button
  3. Press the Cal Wizard key
  4. Choose Use Electronic Calibration
  5. On this screen you should see the model number of your E-Cal followed by a five digit serial number.
