Performance Tests and Checks
System Performance Verification
PNA Series Microwave Network Analyzer System N5251A
Materials Required
The following materials are required to run the tests:
• N5251A system (including system cables)
• 85059A 1.0 mm Calibration and Verification kit
• System Verification program, revision A.05.10 or later. To check the program revision, open
the System Verification utility (step 2 in “Verification Procedure” on page 6-8), then click the
Help tab. The System Verification utility is an independent program installed on the PNA.
Instructions for updating the System Verification utility are located at:

General Preparation
Prepare for performance verification by completing the following procedure:
1. Measure the environment temperature. The temperature must be between +20 C and +26 C.
Additionally, the temperature cannot vary by more than ±1 C after calibration.
2. Apply power to the system components in the following order:
a. N5261/2A millimeter head controller
b. N5227A
PNA
3. Remember to allow at least 90 minutes for warm up and temperature stabilization of the
components. The temperature of the standards in the 85059A 1.0 mm Calibration and
Verification kit must also be stable at the system ambient temperature.
