DVG7 module adjustment procedures
13. Repeat steps 11
and 12 until the average attenuation measured value (μ)is
within 1 mV of the corrected attenuation value.
14. Record the new
measured attenuation corrected value in the Signal 1
amplitude row After adjustment value column of the D VG7 output amplitude
table.
15. Option BK only: Adjust the BLACK 1 output amplitude as follows:
a. On the DVG7,
move the cable from the SIGNAL 1 output to the
BLACK 1 output.
b. On the DVG7
, move the cable from the SIGNAL 2 output to the
BLACK 2 output.
c. Locate va
riable resistor R807 on the DVG7 circuit board. (See Figure 9-1.)
d. Repeat steps 7 through 14 for the BLACK 1 output using R807 to adjust
the ampl
itude.
This completes the output level adjustment procedures.
