Timing application
The Timing application uses a reference to evaluate the timing of the input of
single-link SDI, quad-link SDI, or IP formats (ST2022-6 or ST2110-20). The
timing of the input is compared to the expected frame time according to the
reference alignment.
SDI versus Black Burst is available in standard. SDI versus PTP, IP versus PTP,
Black Burst versus PTP requires Option MP2-IP-MEAS.
For analog references (Black Burst or Tri-Level sync) the relative position of the
horizontal and vertical sync pulses are compared to the input signal. In the case
of PTP the current time is obtained and compared to the SMPTE Epoch. When
an input is configured for ST2022-7 style redundant streams, circles for Path 1
(green) and Path 2 (blue) will appear, otherwise only a single path will display.
(See
Figure 125
.) When the input signal is fully aligned with the reference, both
circles will be in the center of the display indicated by the + symbol.
NOTE.
PTP must be locked to use the Timing application with PTP references.
