CHAPTER 6
Operator Maintenance
6.1 Introduction
This chapter describes the procedures for Preventive Maintenance tasks that can be performed by
operators.
NOTE: There are additional Preventive Maintenance tasks that require
that the service technician has attended a formal training program for
service of the amplifier. (See Table 6-2.) Refer to the Service Manual for
this product for a discussion of these tasks.
It is recommended that a daily log should be kept of all the meter readings. This can be helpful in
identifying trends and potential problems. The daily log is a good source for clues that could
indicate an intermittent or marginal condition. Any increase in reflected power or unexplained
fault conditions could point to a deteriorating condition.
6.2 Preventive Maintenance Tasks
To function safely and effectively, the Ka Band TWTA requires periodic maintenance. This
consists of inspection, cleaning, testing, and calibration of the subsystems at designated intervals.
Refer to Table 6-1 for the Preventive Maintenance tasks to be performed by operators. Table 6-2
outlines preventive maintenance tasks to be performed by a service technician.
Operator Preventive maintenance includes visual inspection and cleaning per Table 6-1. Most of
these tasks are performed with the AC power removed. Details are listed in the following
paragraphs.
