Troubleshooting

This chapter provides procedures that check all operational characteristics of a Flex Max901e that
is suspected of being faulty.

Tools and Materials

Quick Forward Outage Check

Power Supply Troubleshooting

Forward Field Testing

Return Field Testing

Overview

These procedures check all operational characteristics of a Flex Max901e that is suspected of being
faulty. Troubleshooting flow diagrams are provided beginning on page 6-7.

The following information is required for Forward and Return Field Testing:

■

The operational gain of the amplifier (see C-COR Amplifier Specification Sheets)

■

System Forward and Return High and Low Balancing Carrier levels for the amplifier being
tested (see the System Map or Amplifier Data Sheet

)

If available, historical Amplifier Data Sheets will aid in troubleshooting a faulty amplifier.

Verify the following prior to beginning any test procedure:

■

The amplifier is grounded.

■

All tap outlets, active unused ports, ends of cables, and branch points are terminated with
a 75

Ω

impedance.

■

A true RMS, AC-coupled voltmeter is available for AC voltage measurements. Non-true
RMS AC voltmeters will give up to a 10% higher reading than actual. DC voltage
measurements will not be affected.

Note

Most System Maps list the input and output signal levels at bandedge

frequencies established for 68º F (20º C). If necessary, refer to Calculating Balancing
Carrier Levels on page 5-6 and Temperature Compensation on page 5-6.
