1)
Measure the picture period noise levels of pins 13, 14, and 15 with an
oscilloscope.
(n13, n14, n15 (Vp-p))
2)
Calculate the S / N for each pin.
N13 = 20 × Log (2.5 / (0.2 × n13))
N14 = 20 × Log (2.5 / (0.2 × n14))
N15 = 20 × Log (2.5 / (0.2 × n15))

1)
Connect a 3.5-V external power supply to pin 13 via a 100- resistor
(I#13) and measure the sink current on pin 13.
2)
Perform the same test on pins 14 and 15. (I#14, I#15)

1)
When the temperature changes through the range 20°C to +65°C,
measure the changes in the picture period amplitudes of pins 13, 14, and
15.
2)
Calculate the voltage changes per degree of temperature. (t13, t14,
t15)
