• Typical conditions when testing
1. Input signal
1) VIF: fP = 38.9 MHz, VIN = 90 dBµ
Video modulation : modulated signal is 10-staircase. Modulation m = 87.5%
IN = 90 dBµ, pin 25 input level approx. 84 dBµ
V
2) SIF: fS = 6.0 MHz, VIN = 90 dBµ, modulated signal fM = 400 MHz, deviation: PAL±50 kHz, NTSC±25 kHz
3) Video: 10-stair-step 0.6 V[p-p] (VBW = 0.42 V[0-p])
4) Chroma: Color bar signal: Burst level 150 mV[p-p]
Rainbow signal: Burst level 150 mV[p-p]
5) Sync. signal: 0.6 V[p-p]
