Measure V3: the output amplitude when the input
signal burst level is set to 40 IRE and the
chrominance level is set to 80 IRE.
Calculate the following formula.
OVL2 = V3/V1
Measure V4: the output amplitude when the input
signal burst level is set to 20 IRE and the
chrominance level is set to 80 IRE.
Calculate the following formula.
OVL3 = V4/V1
Measure V0: the output amplitude.
Next, set the input chrominance signal (CW)
frequency to 3.08 MHz and measure V1: the output
amplitude.
Calculate the following formula.
CPE308 = 20log(V1/V0)
Measure V2: the output amplitude when the input
chrominance signal (CW) frequency is 3.28 MHz,
and V3: the output amplitude when the input
chrominance signal (CW) frequency is 3.88 MHz.
Calculate the following formula.
CPE = 20log(V3/V2)
Measure V4: the output amplitude when the input
chrominance signal (CW) frequency is 4.08 MHz.
Calculate the following formula.
CPE05 = 20log(V4/V1)
Measure V5: the output amplitude.
Next, measure V6: the output amplitude when the
input chrominance signal (CW) frequency is set to
3.08 MHz.
Calculate the following formula.
CPE308 = 20log(V6/V5)
Measure V7: the output amplitude when the input
chrominance signal (CW) frequency is 3.28 MHz,
and V8: the output amplitude when the input
chrominance signal (CW) frequency is 3.88 MHz.
Calculate the following formula.
CPE = 20log(V8/V7)
Measure V9: the output amplitude when the input
chrominance signal (CW) frequency is set to 4.08
MHz.
Calculate the following formula.
CPE05 = 20log(V9/V6)
