In making the single-tone interference test, Wave Analyzer Model 302A
is selected as the test instrument. This test set is selected because
it has the capability to
a.
furnish a random-noise signal as well as a test tone.
b.
terminate the receive line in its characteristic impedance.
c.
furnish any test tone within its tuning range when using the BFO.
d.
select the interfering tone frequency on the line and measure its
level.
13.
Assume that you are making a test for maximum change in
audio
frequency. You can tell that the audio frequency has changed by
a.
listening first to one frequency, then the other.
b.
comparing the reading of the two frequency counters.
c.
comparing the two frequencies by means of an oscilloscope trace.
d.
observing the readings on one frequency counter, using a return
reference circuit.
SITUATION
Assume that you are performing
a
terminal
test
on
the
circuit shown in figure 1-12.
Exercises 14 through 18 are based on this situation.
