Special Precautions
When performing the procedures, observe the following precautions:
•
Minimize vibration and movement of the system, attached components, and test cable.
•
Clean and check the pin depth and condition of all adapters, test port cables, calibration components,
and impedance transfer standards.
•
Pre-shape the test cable so as to minimize its movement during calibration and measurement activities.
Procedure
1.
Set up the MS464XX VNA and MN469XC Test Set per the MN469xC Series Test Set Installation Guide,
part number 10410-00737.
2.
Power up the test set and VNA per the
Power Up Sequence
of the MN469xC Series Test Set Installation
Guide. Allow the system to warm up at least 90 minutes.
3.
Using the GPIB interface cable to connect the external computer/controller to the VNA rear panel system
GPIB connector. It is the upper GPIB port labeled IEEE488.2 GPIB.
4.
Power up the external computer/controller.
5.
Install the female to female phase equal insertable adapter from the calibration kit to Port 1 of the
MS464xx VNA. This converts Port 1 from a male test port to a female test port.
6.
Install the female to female phase equal insertable adapter from the calibration kit to Port 3 of the
MN469xC. This converts Port 3 from a male test port to a female test port.
7.
Install the Test Port Cable to Port 2 of the MS464xx VNA and then the male to female phase equal
insertable adapter from the calibration kit to the open end of the cable.
8.
Install the Test Port Cable to Port 4 of the MN469xC and then the male to female phase equal insertable
adapter from the calibration kit to the open end of the cable.
9.
Run the MS464XX System Verification software.
10.
Insert the USB memory device (also called a “USB flash drive”) supplied with the verification kit to an
available USB port on the external computer/controller. Set the data location of the verification software
to the USB memory device when prompted.
11.
Follow the directions displayed on the computer to perform calibration with the appropriate calibration
kit.
12.
Follow the directions on the computer to perform measurements of impedance transfer standards of the
appropriate verification kit.
13.
Pass/Fail status of the measurements is displayed on the computer. The software can also provide a hard
copy printout of the measured data, measurement uncertainties, and the impedance transfer standards
used.
14.
If the verification fails, check the connectors of the VNA test ports, calibration kit devices, the impedance
transfer standards, and test port cables for damage, cleanliness, and proper connection and torquing.
Also check the phase stability of the test port cables. These are the most common causes for verification
failures.
