value：
Model B+ (v)
M123SP 110±2.0
21E10 110±2.0
2. RF AGC adjustment
AGC Alignment Procedures:
1) Apply 8-scale gray signal (80dB), then adjust AGC data in D-mode to get the noise
picture ( snow picture) disappear exactly. Test Pin 1 of TU101 (IF output) and
record the voltage value as V1P-P.
<Illustrate as Picture A>
2) Apply 8-scale gray signal (80dB), and then adjust AGC data in D-mode until the
synchronization signal distortion appear exactly. Test Pin 1 of TU101 (IF output)
and record the voltage value as V2P-P. <Illustrate as Picture A>
3) Calculate the value of VP-P with the formula: VP-P＝(V2P-P×V1P-P)1/2
Apply 8-scale gray signal (80dB), test Pin 1 of TU101 (IF output), adjust AGC data
until the voltage of Pin 1 of TU101 VP-P＝(V2P-P×V1P-P)1/2。
4) Test three units according to 1)，2)，3) steps, and record the values of AGC in three
units. Take the average value as benchmark.
Remarks:
Comparing test is necessary due to different probe of Oscilloscope and different Test
Circuit (Picture A).
1) AGC voltage value should be tested afresh, due to the type/supplier of Tuner
or Saw filter changed, or other related components changed.
