Input SIG5 (VL = 150mV) to (A) and SIG2

(level variable, 3.58MHz burst/chroma phase

= 180°, or 4.43MHz burst/chroma phase =

±135°) to (B), and measure the output

amplitude at TP40. Gradually reduce the

SIG2 amplitude level and measure the level

at which the killer operation is activated.

the maximum amplitude at TP40 as VB, the maximum

amplitude at TP43 as VG, and the maximum amplitude

at TP45 as VR.
