Agilent Technologies e4418b, e4419b manual Safety Considerations, Introduction

Adjustments

Introduction

	Introduction
	This chapter describes adjustments and checks which ensure proper
	performance of the power meter. Adjustments are not normally required
	on any fixed periodic basis, and normally are performed only after a
	performance test has indicated that some parameters are out of
	specification. Performance tests should be completed after any repairs
	that may have altered the characteristics of the power meter. The test
	results will make it possible to determine if adjustments are required.
	Allow 30 minutes for the power meter to warm up, and then remove the
	cover, for access to the test and adjustment points.
	To determine which performance tests and adjustments to perform after a
	repair, see “Post-Repair Adjustments”, on page 3-3.
	Safety Considerations
	This warning must be followed for your protection and to avoid damage to
	the equipment being used.
WARNING	Adjustments described in this chapter are performed with
	power applied to the instrument and with protective
	covers removed. Maintenance should be performed only by
	trained personnel who are aware of the hazards involved.
	When the maintenance procedure can be performed
	without power, the power should be removed.
