The following controls adjust the timing of the video frame synchronizer. Because of internal processing
delays (approx. 3+ lines), a phase setting of zero clocks / zero lines will guarantee one frame of delay in
the synchronizer.
Vertical Phase (deg):
This slider control is used to vary the vertical phase of all the output signals from the MVPHD-24
(including the sync reference outputs). When genlocked, this phase adjustment is with respect
to the genlock source. This control indicates the vertical phase in degrees.
See chapter 5 for tips on using this feature.
Horiz Phase (clocks):
This slider control is used to vary the horizontal phase of all the output signals from the MVPHD-24
(including the sync reference outputs). When genlocked, this phase adjustment is with respect to
the genlock source. This control indicates the horizontal phase in video pixel clocks.
Subcarrier Phase (deg):
This slider control is used to vary the subcarrier phase of the composite and Y/C outputs. When
genlocked, this phase adjustment is with respect to the genlock source. This menu indicates
the subcarrier phase in degrees.
Free Run Freq Adj (ppm):
This slider control is used to vary the MVPHD-24’s master clock frequency while in Free Run
mode. This menu indicates the adjustment in parts-per-million (ppm). The range is +/- 8ppm
which is equivalent to 0.0008%.
