Input SIG5 (VL = 150 mV) to (A) and SIG1 (–6 dB, 100 kHz,
no burst) to (D) and (E).
When TINT = 128, let VR0 be the T46 output amplitude
(100 kHz) and let VB0 be the T41 output amplitude (100 kHz).
When TINT = 255, let VR1 be the T46 output amplitude and
let VB1 be the T41 output amplitude.
When TINT = 0, let VR2 be the T46 output amplitude and let
VB2 be the T41 output amplitude.
Then calculate the following formulas.
GEXRMX = 20log (VR1/VR0) GEXRMN = 20log (VR2/VR0)
GEXBMX = 20log (VB1/VB0) GEXBMN = 20log (VB2/VB0)
Input SIG5 (VL = 150 mV) to (A) and SIG1 (0 dB, 100 kHz,
no burst) to (D).
Let VEXB be the T41 output amplitude (100 kHz) and
VEXBG be the T44 output amplitude (100 kHz).Calculate
VEXGB = VEXBG/VEXB.
Input SIG5 (VL = 150 mV) to (A) and SIG1 (0 dB, 100 kHz,
no burst) to (E).
Let VEXR be the T46 output amplitude (100 kHz) and
VEXRG be the T44 output amplitude (100 kHz).
Calculate VEXGR = VEXRG/VEXR.
Input SIG5 (VL = 150 mV) to (A) and SIG1 (0 dB, 100 kHz,

Let VEXB be the T41 output amplitude (100 kHz) and
VEXBG be the T44 output amplitude (100 kHz).Calculate
VEXGB = VEXBG/VEXB.

Input SIG5 (VL = 150 mV) to (A), and to (B),
input SIG2 (0, +6, and –20 dB, 3.58 MHz,
burst/chrominance phase = 180°, and also
4.43 MHz, burst/chrominance phase = ±135°).
Measure the T53 output amplitude, and let V0,
V1, and V2 correspond to 0 dB, +6 dB, and
–20 dB, respectively.

phase = 180°, and also 4.43 MHz,
burst/chrominance phase = ±135°).
Measure the T44 output amplitude. Modify the
SIG2 burst frequency, until the killer is
released. Measure the frequency f1 that
appears in the T41 output.
