Edge Filter. Enables or disables the Edge Filter on serial digital video signals that
have a filter. This control has no effect on signals without a filter. Use the left
(◄) or right (►) arrow button to select between Enable and Disable. Press the
ENTER button to confirm the selection.
When the edge filter is enabled, certain data transitions between two levels are run
through a low-pass filter to set rise times, pulse widths, and to prevent ringing.
If the filter is disabled, the edges will not be filtered. The filter should not be
disabled in broadcast environments.
Edge filtering is not necessary in certain environments, such as digital cinema
applications and several types of picture monitors and projectors. In these cases,
disabling the edge filtering will result in instantaneous level changes for adjacent
color bars.
AV Timing Mode. Turns the AV Timing Mode on or off. Use the left (◄) or right
(►) arrow button to select between Enable and Disable. Press the ENTER
button to confirm the selection.
In the AV Timing mode, the video and audio are continuously cycled between
being on as configured for 1 second then set to black and muted for 4 seconds.
Use this signal to measure the AV delay through a system with the AV Timing
mode on an appropriate Tektronix waveform monitor or rasterizer.
EDH. (SD output mode only) Turns the insertion of EDH packets on or off. Use
the left (◄) or right (►) arrow button to select between Enable and Disable.
Press the ENTER button to confirm the selection.
