Performance Verification
4.1 Introduction
• This chapter provides step-by-step procedures to verify performance of the Series 12000A
Microwave Synthesizers for all three models (Modulation related items are in Section 4.4 for the
Series 125XXA/127XXA models)
• Sectional header page references are only provided for items pertaining directly to performance
verification testing
• The required warm-up time before testing is 72 hours. The warm-up period can be reduced to
30 minutes if timebase accuracy is not to be tested for all three models
• In these procedures, the instrument being tested may be referred to as the 12000A or UUT (Unit
Under Test) for all three models
4.1.1 Recommended Equipment
The following equipment is recommended before starting the performance test routines (the
recommended equipment can be substituted provided the specifications are sufficiently compatible):
