Adjustment Procedures |
@ Output Voltage Adjustment VTVM
(Output Terminal: No load) Unit Under Test
(1) Set the DC supply voltage to 14V.
(2) Connect a VTVM to TP 3 and TP 4. (Figure 6)
(3) Rotate the semi-fixed variable resistor (VR102)
to be 55.0V DC on the voltmeter.
@ Cut-Off Circuit Adjustment
(1) Set the DC supply voltage to 10.40V.
(2) Connect an oscilloscope and a mili-voltmeter to Range at 30V or 50V
Figure 6
TP 1 and TP 2 (Figure 7) (Read this voltage value to be at 0 dB point.)
(3) Rotate the semi-fixed -variable resistor (VR101) Oscilloscope
fully
counterclockwise.
Mili-voltmeter
(4) Read voltage on the mili-voltmeter and its reading
is at O dB point. (Figure 7)
(5) Rotate the VR101 clockwise slowly and adjust it
to be —1 dB down from voltage as indicated in
above step (4).
