3. Live Input Pass-through
When neither GEN_BASIC or GEN is installed, video received on either input (SDI or EYE as
configured on the System page of the Config window) is automatically passed through to the
corresponding SDI Output. This facility may be used to pass the signal on either to another OTR
1001 or to some other type of test and measurement instrument for further analysis.
With GEN_BASIC or GEN installed, live input pass-through has to be specifically selected. The
steps used are essentially the same as those used to play out any pattern i.e. pick out the
appropriate pattern on the Gen window and play it. You also need to set the
Genlock to lock to
the incoming signal (as described in Section P.2), and if you have defined safe action/safe title
cages for the input (see Section F.3), you may also wish to includes these cages on the output by
ticking the
Show Cage option in the Gen window Properties. However you don’t need to set the
Output Video Standard as that is automatically matched to the incoming Input Video Standard.
The pattern thumbnails included in the Gen window automatically start with ones for passing
each SDI Input through to both outputs and a wider one that allows the two inputs to be passed
through to their respective outputs. These patterns are differentiated from other patterns by being
shown against a cyan background. These thumbnails will either show the input being received or
‘No Input’ if none is being received or ‘Not Available’ if the analyser is currently processing
video output from the built-in generator and the internal loopback between the generator and the
analyser is therefore in action.

To pass a live input through:
Move the focus to the appropriate
thumbnail and push the GENERAL knob. Click on the appropriate thumbnail.
Note: The signal is played out exactly as received via the input (except for any cage that you
have opted to show). In particular, while live input is being output in this way, the output video
standard is automatically switched to the input video standard.
4. Displaying the Test Signal on a Monitor
At the same time as a test signal is output via one of the SDI outputs, the signal can be displayed
on a monitor attached to the ANA OUT port.
