Performance Verification

4-1

INTRODUCTION

This chapter provides specific procedures to be used to verify that the

 

 

373XXA is making accurate, traceable S-parameter measurements. You

 

 

should perform the verification procedures in paragraph 4-3, “Verifying

 

 

Measurement Accuracy,” at least once annually.

 

 

Additionally, this chapter includes procedures that may be used to

 

 

measure the following key system performance parameters:

 

 

￿ Effective Source Match

 

 

￿ Effective Directivity

 

 

￿ System Dynamic Range

 

 

￿ Frequency Accuracy

 

 

￿ Power Level Accuracy

 

 

The Operational Tests described in Chapter 3 should be performed

 

 

prior to verifying system performance.

 

 

Please ensure you have read and fully understand the servicing con-

 

 

cepts for the 373XXA presented in Chapter 1 prior to continuing with

 

 

this chapter.

determine system measurement integrity to a large extent.

These are all user controlled conditions, and as such, should be evalu- ated periodically for impact on system performance. If these conditions vary significantly with time, the system verification procedures should be performed more often than the recommended annual cycle.

Standard Conditions The standard conditions specified below must be observed when perform- ing any of the operations in this chapter — both during calibration and during measurement.

Warm-up Time: One hour minimum.

Environmental Conditions:

Temperature: 23 +/- 3 deg C

Relative Humidity: 20-50% recommended.
