of the 7 ns region, check that the eye is open between transitions. See the
following figure.
11. Record the amplitude (ΔV) in the test record for 1.5 Gb/s. Amplitudes
between 745 mV and 849 mV are acceptable.
12. If your instrument has Option 3G, perform step 13 through step 15. Otherwise
skip to "Slot 1 serial output check". (See page 90.)
13. Move the cable connection from the TG700 HDVG7 to the HD3G7 SIGNAL
1 output. The waveform on the test oscilloscope will change, reflecting the
3 Gb/s serial rate. Select 100% color bars on the HD3G7.
14. Check the signal amplitude, using the 7 ns wide region without transitions.
The amplitude should be very similar to that observed in step 7. Outside
of the 7 ns region, check that the eye is open between transitions. See the
following figure.
