Table 28: Composite analog physical characteristics; composite input characteristics (Option CPS) (cont.)
Characteristic Performance requirement Reference information
Slow Mode <10% attenuation, <10% peaking.
Slow mode typical peaking 8% at 50 and
60 Hz.
Blanking Shift with 10 to 90% APL
Change ≤ 1 IRE (7 mV PAL)
Blanking Shift with Presence and
Absence of Burst ≤ 1 IRE (7 mV PAL). Typically 0 mV.
Lock Range “50 ppm, remains locked”. Vector typically OK to ± 80ppm. WFM display
typically locked to (plus-min) 200ppm.
Lock in Presence of Hum ± 1.0 V
p-p
, on 0 dB signal, remains locked.
Lock in Presence of White Noise Signal/Noise ratio of 32 dB, 5 MHz bandwidth
on black burst, remains locked.
Color Framing Correct color framing detected for signals
having < 45 SCH Phase error with burst
present.
Clamp Range (typical) Signals with back porch within ± 1V range. Clamp can keep signal in this range displayed
at correct position on screen. Signals outside
this range may be displayed offset upward
or downward.
