Chapter 4 Maintenance
4.1 INTRODUCTION
The E&I A1000 RF amplifier requires no periodic maintenance. The instrument is
unconditionally stable and is fail-safe under all load conditions. Damage can only
be externally caused by the incorrect selection of the AC supply voltage or by an
input signal in excess of the specified 1 volt rms equivalent to a power level of 13
dBm or a power level of 1 dBm for greater than one minute.
This chapter therefore, deals only with certain fundamental procedures for fault
location.
