4.  MAINTENANCE 

4.1  GENERAL MAINTENANCE INFORMATION 

The Model 125W1000A requires very little maintenance since it is a relatively simple instrument.  It is built 

with etched circuit wiring and solid-state devices that will ensure long, trouble free life.  However, should 

trouble occur special care must be taken in servicing to avoid damage to the devices or the etched circuit board. 

Since the components are soldered in place, substitution of components should not be resorted to unless there 

is some indication that they are faulty.  In addition, take care when troubleshooting, not to short voltages across 

the amplifier.  Small bias changes may ruin the amplifier due to excessive dissipation or transients. 

Components in AR instruments are conservatively operated to provide maximum instrument reliability.  In spite 

of this, parts within an instrument may fail.  Usually, the instrument must be immediately repaired with a 

minimum of down time.  A systematic approach can greatly simplify and, thereby, speed up the repair. 

However, due to the importance of the amplifier's alignment, it is recommended that when failure is caused by 

breakdown of any of the components in the signal circuits, the amplifier be returned to the factory for part 

replacement and amplifier realignment.  Shipping instructions are as follows. 

To return an item, contact AR Customer Service for an RMA number and shipping instructions.  Returns from 

outside the United States are not permitted without prior authorization.  If shipping from outside of the United 

States, closely follow all directions on the RMA form for return shipping and marking.  See warranty statement 

at rear of manual. 

4.2  DISASSEMBLY PROCEDURE 

 

CAUTION: 

Extreme caution should be exercised when troubleshooting this unit, 

particularly when measuring voltages in the power supply section of the 

unit.  Hazardous voltages do exist in the unit that could cause serious injury 

to any personnel performing the measurements. 

The amplifier can be removed from the housing by removing four screws from the front panel and four screws 

from the rear securing brackets. The amplifier can then be slid from the housing. The top and side covers can 

be removed to gain access to the RF assemblies. The power supply and remote interfaces are accessible by 

removing the bottom cover.
