3. Connect the Tri-Black 2 output to an oscilloscope or suitable Analyzer using a 75ohm
BNC cable.
4. Set the oscilloscope / Analyzer to view the Tri-Black 2 signal.
5. Check that the oscilloscope / Analyzer displays the appropriate Tri-Black 2 signal.
6. Check that the Tri-Black 2 signal is as configured in the menu, and that selecting and
editing entries in the menu by using the rotary/push control, the configuration of the
Tri-Black 2 signal changes accordingly.
7. Return to step 2, set for < Video Channel 09 = Tri Black 3 >, and repeat steps to check
the Tri-Black 3 outputs.
8. Return to step 2, set for < Video Channel 10 = Tri Black 4 >, and repeat steps to check
the Tri-Black 4 outputs.
9. Return to the Top Level menu using the [ Back ] button.
Serial Digital Video Signal Outputs
Each SDI Video output channel can be configured to produce SD-SDI, HD-SDI or 3G-SDI.
SD-SDI Video outputs are always available. HD- and 3G-SDI outputs are only available if the

From the Top Level menu:
1. Select < -Video >.
2. Select < Video Channel 01 = SDI+Black 1 >.
3. Connect the SDI1 Pattern output to the Serial Digital Video Analyzer using a 75ohm
BNC cable.
4. Set the Serial Digital Video Analyzer to view the Serial Digital Video signal.
5. Check that the Serial Digital Video Analyzer displays the appropriate Serial Digital
Video signal. If available, check the status of the Serial Digital Video signal on the
Analyzer by setting it to display the relevant data.
6. Check that the Serial Digital Video signal is as configured in the menu, and that
selecting and editing entries in the menu by using the rotary/push control, the
configuration of the Serial Digital Video signal changes accordingly.
7. Move the 75ohm BNC cable to the SDI1 Black output.
Note
— The Tri-Black 2 / 3 / 4 outputs can be configured to produce either traditional “bi-level”
Color Black (i.e. PAL / NTSC) or Tri-Level syncs.
Note
— The format of the SDI Black 1 (and 2) output(s) follows that of the associated SDI
Pattern output; i.e. they operate as a pair of “linked” outputs.
