5. Verify that the blanking level is within the range of +50 mV to –50 mV.
6. Record the measured value in the test record for Tri-level Sync Output
Blanking Level.
7. Change the oscilloscope vertical scale to 10 mV/div.
8. Align the blanking level with the center graticule line on the oscilloscope.
9. Change the oscilloscope vertical offset to 300 mV.
10. Verify that the high level of the signal (sync amplitude plus) is within the
range of +0.6 div to –0.6 div to the center graticule (except for ringing of
the rising edge).
11. Record the measured value in the test record for Sync Amplitude plus.
12. Change the oscilloscope vertical offset to –300 mV.
13. Verify that the low level of the signal (sync amplitude minus) is within the
range of +0.6 div to –0.6 div to the center graticule (except for ringing of
the falling edge).
14. Record the measured value in the test record for Sync Amplitude minus.
15. Set the vertical offset to 0 V and change the vertical gain to 50 mv/div.
16. Change the BNC cable connection from the BLACK 5 connector to the
BLACK 4 connector on the SPG8000 and repeat steps 5 through 14.
