Preparing the Analyzer for Use

If the IF section will not power up

Check that the power cord is connected to the IF section and to a live power source.

Check that the front-panel switch is on ( l ).

Check that the voltage selector switch is set properly.

See ‘’To change the IF section’s line-voltage switch’’ on page 7-10.

Check that the fuse is good.

See ‘’To change the IF section’s fuse’’ on page 7-12.

Check that the IF section’s air circulation is not blocked.

Cooling air enters the IF section through the rear panel and exhausts through both sides. If the IF section’s air circulation is blocked, the IF section powers down to prevent damage from excessive temperatures. The IF section remains off until it cools down and its power switch is set to off ( O ) then to on ( l ).

Obtain service, if necessary. See ‘’Need Assistance?’’ at the end of this guide.
