KEY SYSTEM PARAMETERS PERFORMANCE VERIFICATION

ANRITSU Verification Kit appropriate for the 373XXA model; refer to paragraph 4-3.

GPIB cable (ANRITSU PN: 2100-2), or equivalent

	Procedure:
	Step 1.	Using the GPIB cable, connect the external computer/con-
		troller to the IEEE 488.2 GPIB Interface port on the
		373XXA rear panel.
	Step 2.	Insert the CD ROM into its drive and install the 2300-237
		software.
	Step 3.	Follow the directions displayed on the computer screen to
		perform all tests.
		If the calibration fails, check the connectors of the calibra-
		tion kit devices and the impedance transfer standards for
		damage, cleanliness, and proper connection and torquing.
		These are the most common causes for verification failures.
		If the problem persists, check system Directivity, Match,
		and Dynamic Range, as described in the next paragraph.
4-5KEY SYSTEM	The following paragraphs describe procedures for automated measure-
PARAMETERS	ment of the key system performance parameters listed below. Measure-
	ment of these parameters is not required for system verification; however,

it is highly recommended to ensure that the complete 373XXA measure- ment environment is stable and capable of supporting accurate measure- ments.

￿Effective Source Match

￿Effective Directivity

￿System Dynamic Range

￿Frequency Accuracy

￿Power Level Accuracy

Measurement As with the verification procedures, the quality of the measurement of the Environment system performance parameters listed above is very dependent on the

Considerations measurement environment.

The complete 373XXA measurement environment consists of:

￿Condition and stability of the test ports, through-cable, and calibra- tion kit mating connectors.

￿Settings and stability of the surrounding environment, especially temperature, humidity, and vibration. To maintain the highest sys- tem performance, avoid changing these conditions, especially tem-
