Note 1. PIF IN: f = 58.75MHz, fm = 1kHz, 30% AM Modulation.
Adjust PIF input level so that the detected output of P12 with high impedance probe will be
6VP−P and measure the input level.
Note 2. Measure PIF Input Level V1, V2 same as Note 1.
Apply P7 = 9V at V1
Apply P7 = 3V at V2
ΔA = 20log (V1/V2) (dB)
Note 3. Gain Reduction = 40dB.
PIF IN: CW f = 58.75MHz, APL 50%, 87.5% AM Modulation.
(1) Setting ATT so that the sync tip level of P12 will be 2V DC.
(2) Measure DG and DP.
Note 4. PIF IN: No Signal.
Measure output level of P12.
Note 5. PIF IN: f = 58.75MHz CW 15mVrms.
Measure DC level of P12.
Note 6. PIF IN: f = 58.75MHz, APL 100% 15mVrms.
Measure detected output voltage.
Note 7. PIF IN: f = 58.75MHz ±10MHz variable or sweep 15mVrms.
Measure DC level of P12.
Note 8. PIF IN: 58.75MHz, 1kHz, 87.5% AM Modulation 15mVrms.
(1) Setting AGC so that output AC level of P12 will be 2VP−P.
(2) Measure CL of P12 after setting 0% AM of SG.
Note 9. Measure I 2nd carrier of P12 same as Note 8.
Note10. PIF IN: SG = VARIABLE, 15mVrms CW.
(1) P1 DC voltage will be 4.5V.
(2) Apply SG signal to P3 and measure P1 voltage change.
