TM 11-5820-401-34-3/0967-LP-432-3060

5-7. RECEIVER AUDIO DISTORTION TEST. (CONT)

TEST EQUIPMENT AND MATERIALS

Matching Unit CN-901/U

Power Supply PP-1104(*)/G

Resistor, 600-ohm 5%, 2-watt

Distortion Analyzer TS"723(*)/U

Rf Cables (two) RG.58/U

Frequency Counter AN/USM-207

Test Cable No. 1

Signal Generator AN/URM-103

Adapter (T-Connector) UG-274 B/U

NOTE

The 600-ohm resistor provides an impedance matching load for the audio transformer.

The resistor is used in place of Loudspeaker LS-454/U, which would issue a loud,

distracting tone when the R-442/VRC VOLUME control is adjusted during the test. If no

600-ohm resistor is available, however, the loudspeaker must be connected.

TEST SETUP. Connect test equipment as shown in test setup diagram

Turn on test equipment. Allow at least 15 to 30 minutes for warmup.
