1710J-Series Waveform Monitors
6–11
4. Move A3J500 to the (2–3) ON position.
5. Display the signal with the 2 LINE sweep.
6. Select CH B input.
7. Position the signal blanking level to the graticule baseline (0 IRE or
0.3 mV).
8. Switch television test signal generator linearity signal APL (Average Picture
Level) between 50% and 10% and 50% and 90%.
9. Check that the signal blanking level moves less that 1 IRE (NTSC) or 7 mV
(PAL).
10. Use a 75
W
coaxial cable to connect the television test signal generator
multiburst signal to the CH A input. Terminate the remaining side of the
loop-through input with a 75
W
end-line terminator.
11. Select CH A and EXT REF.
12. Switch multiburst generator Burst off and on.
13. Check that the blanking level changes less than 1 IRE (NTSC) or
7 mV(PAL).
14. Remove the multiburst input from the CH A input.
15. Use a 75
W
coaxial cable to connect the function generator output through a
X10 (75
W
) Attenuator to the CH A input.
16. Move A3J500 to the 1–2 (off) position.
17. Set the function generator frequency to a 60 Hz (50 Hz PAL) sine wave. Set
the amplitude for a 100 IRE (700 mV PAL) 1710J-Series Waveform Monitor
display.
18. Move A3J500 to the 2–3 (on) position.
19. Check that the display amplitude is 10 IRE (70 mV PAL) or less.
20. Move A3J99 to the 1–2 (slow) position.
21. Check that the display amplitude is 80 IRE (560 mV PAL) or greater.
22. Remove the signal cable and 75
W
terminator from the CHA input.
23. Move A3J500 to the (1–2) OFF position.
