Dual Link Signals

26
The inputs for dual link signals are the same as for SDI signals. Dual Link
monitoring allows you to set up your instrument to monitor higher resolution
signals than can be monitored using the traditional single link input. Dual link
signals are combined in the instrument and then shown as a single signal on a
waveform or other display. (See Figure 13.)

When you set input formats, sample structure, and transport type to Auto in the
CONFIG > SDI Input menu, your instrument automatically configures for
Dual Link signals if SMPTE352M (VPID) is present. If SMPTE352M (VPID)
is not present, you must manually set up sample structure and transport. View
the Video Session Display (STATUS>Display Type>Video Session) to verify
proper configuration.
Your instrument automatically detects the format on signals with SMPTE352M
(VPID) while operating on Dual Link signals. You can then view combined Link
A, Link B, and Alpha Channel information, which can help with the identification
of correct content. Alpha Channel information is visible, if present. The following
illustration is an example of how the signal components would appear. (See
Figure 14.)
