SDI Serial Output
Amplitude
52
This completes the SDI Input Equalization Range checks.
This test verifies that the Serial Output signal amplitude is within specifications.
All instruments have an SDI OUT signal output on the rear panel. The content of
this signal is determined by the Config> Outputs> SDI Output setting.
Serial output check (all models).
1. Set the waveform monitor to the Factory Preset.
2. Connect the TG700 DVG7 SIGNAL 1 output to the SDI 1A input on the
waveform monitor.
3. Set the DVG7 to provide a 525 270 Mb/s 100% color bar signal.
4. Input 1A should be selected on the waveform monitor. You should see a
stable color bar picture and waveform display.
5. Install the TCA75 adapter in the test oscilloscope CH 1 input. Connect the
waveform monitor mainframe SDI OUT to the oscilloscope CH 1 input.
6. Set the test oscilloscope as follows:
Parameter
CH 1 Vertical
Horizontal:
FastAcq:
Trigger: A Event
Trigger: A>B Seq
7. Activate the test oscilloscope "H Bars" cursors. Set Cursor 1 to the middle
of the bottom trace and Cursor 2 to the middle of the upper trace. Use the
7 ns wide region that does not contain transitions to align the cursors. See
the following figure.
