1.
With
the
equipment
connected
as
shown
in
Fig. 3-4, feed a 1 kHz signal to the input jack.
Adjust the attenuator to obtain a | volt reading
on
the
ac
VTVM.
Note
that
the
audio
oscillator's
output
should
always
be kept at
0.775 volts (0 dB).
The reading of the attenuator
represents
the
input
sensitivity and
should within the limits
given in Table 3-1.
