When operating the data analyzer, the technical controller takes an
initial and a follow-up reading.
The initial reading on the meter
indicates the
a.
b.
total distortion.
c.
fortuitous distortion.
d.
characteristic distortion.
10.
The data analyzer in the DAS10 should indicate zero distortion when
receiving the signal shown in B of figure 2, TM 11-680 extract,
because the
a.
operate and release points occur at identical current values.
b.
line current reaches maximum value on each transition.
c.
selector magnet operation is not delayed.
d.
transition delays are equal.
11.
The difference in transition delay is the same as the difference in
pulse length between marks and spaces in the received signal. If the
difference in transition delay is 6 ms and the speed of transmission
is increased to 100 wpm (13 ms pulses), the percentage of distortion
read by the DAS10 data analyzer should be approximately
a.
5.
b.
24.
c.
46.
d.
86.
12.
Assume that a circuit you are testing shows a total distortion of 15
percent, with all distortion being caused by spacing bias. You will
record this in you log sheet as
a.
15NB.
b.
15S15.
c.
30S15.
d.
45S30.
