*
10 IRE ~20IRE : F800 : 20mV
* Oscilloscope
* DC power
* TP5603 [B-SIG2]
* TP5411 [GLBS]
5.
Adjust *RV so that the forward 10 IRE ~ reverse 10 IRE (A) be-
comes *8.30
±
0.02Vp-p.
Adjustment is no good when 0 IRE ~ 10 IRE voltage is below
100mV.
6.
Confirm that forward 100 IRE ~ reverse 100 IRE (B) is
*3.45
±
0.10Vp-p.
* RV5402 [GL. BIAS]
* RV5603 [GL. GAIN]

B channel
1.
Connect *oscilloscope to *TP5603.
2.
*DC power, apply 3.60
±
0.02V to *TP5611.
3.
Adjust *RV so that 10 IRE ~ 20 IRE becomes *800
±
20mV.
Confirm that 0 IRE ~ 10 IRE voltage is over 7.1V.
