Adjustments Model 8901B
14. The voltmeter
is
now set up
to
measure V, which represents the reference output level. Compute
the desired value of
V,
(for
1
mW) from the equation
where
H
is
the effective efficiency of the thermistor mount at
50
MHz
as
read from the
mount’s label.
Desired
VI
:
Vdc
15.
Adjust A32R4
(LEVEL
ADJ)
until the voltmeter reading
is
the same
as
V, computed
in
step 14.
If
the adjustment
runs
out of range, replace A32Fl.5
with
7100fl and readjust A32R4.
