Measurement Procedure

Bus Condition

Measure V0, the output amplitude (Vp-p). Measure V1,

the output amplitude (Vp-p) for an input chroma (CW)

frequency of 3.08 MHz, and substitute in the following CHR.BPF : 1

formula.

CPE308 = 20log(V1/V0)

Measure V2, the output amplitude (Vp-p) for an input

chroma (CW) frequency of 3.28 MHz, and V3, the

same for 3.88 MHz, and substitute in the following CHR.BPF : 1

formula.

CPE = 20log(V3/V2)

Measure V4, the output amplitude (Vp-p) for an input

chroma (CW) frequency of 4.08 MHz, and substitute in

the following formula.

CHR.BPF : 1

CPE05 = 20log(V4/V1)

Measure V5, the output amplitude (Vp-p). Measure V6,

the output amplitude (Vp-p) for an input chroma (CW)

frequency of 3.08 MHz, and substitute in the following CHR.BPF : 0

formula.

CBE308 = 20log(V6/V5)

Measure V7, the output amplitude (Vp-p) for an input

chroma (CW) frequency of 3.28 MHz, and V8, the

same for 3.88 MHz, and substitute in the following CHR.BPF : 0

formula.

CBE = 20log(V8/V7)

Measure V9, the output amplitude (Vp-p) for an input

chroma (CW) frequency of 4.08 MHz, and substitute in

the following formula.

CHR.BPF : 0

CBE05 = 20log(V9/V6)
