f = 200kHz, 0.3Vp-p input (Fig.2)
0.3Vp-p input, frequency where output
level is –3dB with 200kHz serving as
0dB (Fig. 2)
200kHz input (Fig.2)
200kHz, 2.5Vp-p input (Fig.2)
f = 4.43MHz, 1Vp-p input (Fig.2)
Ratio of 0.7Vp-p white video signal to
"black line" noise. Weighted using CCIR
567. HPF @5kHz, LPF @5MHz. (Fig.2)
1Vrms 1kHz input through 56kΩ.
Attenuation measured to calculate Zin
(Fig.3)
V1 = Pin voltage +0.5V,
V2 = Pin voltage +1V
At output, non-linearity =
1.7Vp-p 5-step modulated staircase.
(Chroma and Burst are 150mVp-p
4.43MHz) (Fig.2)
as above. (Fig.2)
Percentage reduction in sync pulse
(0.4Vp-p), with tip at –1.2V input offset.
