4. Verify that the blanking level is within the range of +50 mV to –50 mV.
5. Record the measured value in the test record for Blanking Level.
6. Change the oscilloscope vertical scale to 10 mV/div.
7. Align the blanking level with the center graticule line on the oscilloscope.
8. Change the oscilloscope vertical offset to 300 mV.
9. 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).
10. Record the measured value in the test record for Sync amplitude plus.
11. Change the oscilloscope vertical offset to –300 mV.
12. 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).
13. Record the measured value in the test record for Sync amplitude minus.
14. Set the vertical offset to 0 V and change the vertical gain to 100 mV/div.
15. Repeat steps 4 through 13 for the Black 2 and Black 3 outputs, making sure to
move the cable to the connector of the output you are testing.
