Performance Verification Checklist
Use the following checklist if you are familiar with the operation of the TSG 95
as well as video and audio performance verification techniques. Step-by-step
instructions for all of the procedures begin on page 4–4.
NOTE
. After initial delivery or long storage, allow a two-hour warm-up time to
re-age the crystal. Thereafter, 20 minute warm-up time is sufficient.
1. Check Subcarrier Frequency
Subcarrier of genlocked generator =
j
PAL: 4.43361875 MHz
±
10 Hz
j
NTSC: 3.579545 MHz
±
10 Hz
2. Check Blanking Level
j
PAL and NTSC: 0 V
±
50 mV
3. Check Sync Amplitude
j
PAL: 300 mV
±
14 mV
j
NTSC: 285.7 mV
±
14.28 mV (40 IRE
±
2 IRE)
4. Check Burst Amplitude
j
PAL: 300 mV
±
14.0 mV
j
NTSC: 285.7 mV
±
14.28 mV (40 IRE
±
2 IRE)
5. Check Sync Rise Time
j
PAL: 250 ns
±
25 ns, 10% to 90%
j
NTSC: 140 ns
±
20 ns, 10% to 90%
6. Check 5-Step Linearity
j
PAL and NTSC: Max diff step difference
≤
1%
7. Check Luminance Amplitude Accuracy
j
PAL: 700 mV
±
7.0 mV
j
NTSC: 714 mV
±
7.14 mV (100 IRE
±
1 IRE)
8. Check Chrominance-to-Luminance Delay and Gain
j
PAL: Delay
≤
10 ns, Gain
≤
2% (14 mV)
j
NTSC: Delay
≤
15 ns, Gain
≤
2% (14.28 mV)
