(1) Adjust ATT so that the sync tip level of P15 becomes 2.0V DC. (2) Measure DP and DG. NOTE 4) PIF IN; No Signal Measure output level of P15. NOTE 5) PIF IN; f = 58.75 MHz CW 15 Wrens Measure DC level of P15. NOTE 6) PIF IN; f = 58.75 MHz 1008 APL 15 MVing Measure detected output voltage.

(2) Measure the level difference [dB] between C-level and 920 kHz level. NOTE 12) SIF IN; fm = 400 Hz 25 kHz dev. 100 GBy FM Modulation Measure the output level at P8. NOTE 13) SIF IN; fm = 400 Hz 25 kHz dev. 100 dBy FM Modulation Decrease the input level so that the detected output level will drop to 3 4B less than P8; then measure the input level. NOTE 14) SIF IN; £ = 4.5 MHz, 100 4B (1) PM: Af = 25 kHz, fm = 400 Hz (2) AM: 308, fm = 400 Hz NOTE 15) SIF IN; f = 4.5 MHz 7.5 kHz dev. 100 dBy vary the frequency so that the detected output level will drop to 3 dB less than the peak; then measure the carrier frequency. NOTE 16) Adjust SIF IN so that the detected output level of Harmonic Distortion becomes 1.5%; then measure the carrier frequency the same as NOTE 15).
