The principle corrective device used to condition VF communication
circuits is an equalizer. For maximum benefit in use of circuits that may
be required to carry data and secure voice signals, the device should be
net loss variation.
b. correcting amplitude versus-frequency distortion.
There are approximately 16 different parameter tests that may be
performed using the TIMS, however one specific test is optional and must be
requested when ordering the test set.
The test that must be requested is
b. peak-to-average ratio test.
c. noise-to-ground test.
Telephone Test Set AN/USM-181 consists of an oscillator, a voltmeter,
and a patching panel. The function of this test set is to measure a circuit
to determine its
a. attenuation, envelope delay, and gain.
Noise-Level-VU Measuring Set Model TTS-37B can be used for several
functions. One function it CANNOT perform is
a. provide a DC output to drive a recorder.
b. determine signal level in dBm.
c. measure noise level in dBrn.
d. furnish a test tone.
