WVR5200 Waveform Rasterizer Specifications and Performance Verification
8. Record the amplitude (ΔV) in the test record for 270 Mb/s. Amplitudes
between 745 mV and 849 mV are acceptable.
NOTE.
The specification range for the SDI outputs is 720 mV to 880 mV (800 mV
±10%). The test limits are narrower than this to allow for the ±3.5% amplitude
uncertainty in the oscilloscope system (±2% for the oscilloscope mainframe and
±1.5% for the TCA75 adapter).
9. Move the cable connection from the TG700 DVG7 to the HDVG7 SIGNAL
1 output. The waveform on the test oscilloscope will change, reflecting the
1.5 Gb/s serial rate. Select 100% color bars on the HDVG7.
10. 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.
