N8486AQ
This test measures the Voltage Standing Wave Ratio (VSWR) of the power sensor's coaxial calibration port at 50 MHz. A network analyzer accompanied with a calibration kit or electronic calibration module is used to perform this test.

[1] Supported N5230A and N5230C Options: This calibration application supports any option that covers the entire frequency range of the UUT.
[2] D-model ECals can only be used with the following network analyzer models and firmware versions:
[3] Supported power sensor options:
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.
85055A - 50 dB attenuator
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 five-digit serial number located on the largest fixed attenuator in the kit.

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 5 digit serial number printed on your unit, then follows these instructions using your network analyzer to locate your serial number:
