802BT/802R Video Test Generator User Guide
HSPW must be even for HDTV sync
The number of pixel clock cycles in the horizontal sync pulse width must be evenly
divisible by 2 for the current video and HDTV sync type selections.
Horizontal pulse width too large
The generator hardware configuration does not support a horizontal sync pulse width that
is greater than the horizontal blanking period.
Horizontal pulse delay not even.
The number of pixel clock cycles in the horizontal sync pulse delay must be evenly
divisible by 2 at the current pixel clock rate for the video format and generator hardware
configuration.
Frame sync pulse width too small
The generator hardware configuration does not support a Frame Sync pulse width less
than horizontal scan period.
Frame sync pulse width too large
The Frame Sync pulse width can not be greater than the total (active + blanked) number of
horizontal scan lines in one frame of video.
Probe sync pulse width too small
The probe sync pulse width is less than minimum supported by the generator hardware
configuration.
Probe sync pulse width too large
The probe sync pulse width is greater than maximum supported by the generator
hardware configuration.
Horizontal pulse delay extends sync beyond blanking
The generator hardware configuration does not support the video format's combination of
horizontal sync pulse delay and pulse width that places any portion of the horizontal sync
pulse outside of the horizontal blanking period.
Vertical serration adjustment too big
The video format's HVSA setting beyond the maximum limit for the video type selected
and generator hardware configuration.
Vertical total too small
The total (active + Blanked) number of horizontal scan lines per frame a progressive scan
(non-interlaced) video format is lees than the minimum supported by the generator
hardware configuration.
