PERFORMANCE VERIFICATION VERIFICATION PROCEDURE

data, measurement uncertainties, and the impedance transfer stan- dards used.

NOTE

The total verification uncertainty in these 373XXA measurements includes the mea- surement uncertainty of the verification standards and the 373XXA measurement uncertainty.

Verification Result The software verification process compares the measured S-parameter Determination data of the impedance transfer standards against the original standard

data for those devices that was obtained using the Factory Standard 360 Vector Network Analyzer System (at ANRITSU). The factory Standard 360 system is traceable to NIST through the ANRITSU Calibration Labo- ratory’s Impedance Standards. These standards are traceable to NIST through precision mechanical measurements, NIST approved microwave theory impedance derivation methods, and electrical impedance compari- son measurements.

The quality of the verification results is very dependent on the degree of care taken by the user in maintaining, calibrating, and using the system. The most critical factors are:

￿ The stability and quality of the devices in the calibration and verifi- cation kits.

	￿ The condition of 373XXA test port connectors and through-cables.
	￿ The pin depths of all connectors, and the proper torquing of connec-
	tions. These same factors also affect 373XXA measurement quality.
	Consult the Operating Manuals supplied with the ANRITSU Calibra-
	tion and Verification Kits for proper use, care, and maintenance of the
	devices contained in these kits.
4-4VERIFICATION	The performance verification procedure for the ANRITSU 373XXA VNA
PROCEDURE	is described below. Refer also to the Model 360X/37XXX VNA Perfor-
	mance Verification Software Users Guide, P/N: 10410-00162, which is lo-
	cated in Appendix E at the rear of this manual. This Software Users
	Guide explains in detail the procedures to be used for the installation and
	operation of the Verification Software on your computer/controller.
	Equipment required:
	ANRITSU 37300A Verification Software, PN: 2300-237 (Version 3.1
	or above of 2300-237 software is necessary to verify the 37397A).
	External computer/controller; refer to Table 1-1 located on page 1-9.
