882 Video Test Instrument User Guide (Rev A.35) 167
The table that follows describes each of the fields in the main panel of the Timing tab.
Entity Field Description / Function
Pixel Rate Sets the pixel rate in pixels (Machine) or microseconds
(Time) of the format.
Horizontal
Rate The horizontal line rate of the format. The HRAT is the
fundamental frequency in the 882. Parameter: HRAT.
Tune The tunning value of the base frame rate (base/tune) for
NTSC color broadcast compatibility. The tuning value is
base/1.001.
Base The base frame rate.
Active The number of active pixels (machine) or microseconds
(Time) of the horizontal video. Parameter: HRES.
Blank The number of active pixels (Machine) or microseconds
(Time) of the horizontal video. This parameter is
calculated.
Total The total number of active pixels (Machine) or
microseconds (Time) of the horizontal video. The total is
the sum of the Active and Blanking. Parameter: HTOT.
Pulse Delay The number of pixels (Machine) or microseconds (Time)
in the blanking preceding the horizontal sync pulse.
Parameter: HSPD.
Pulse Width The number of pixels (Machine) or microseconds (Time)
of the horizontal sync pulse. Parameter: HSPW.
Vertical
Rate The vertical frame rate of the format. Parameter: VRAT.
Active The number of active lines (machine) or milliseconds
(Time) of the vertical video. Parameter: VRES
Blank The number of active lines (Machine) or milliseconds
(Time) of the vertical video. This parameter is
calculated.
Total The total number of active lines (Machine) or
milliseconds (Time) of the vertical video. The total is the
sum of the Active and Blanking. Parameter: VTOT.
Pulse Delay The number of lines (Machine) or milliseconds (Time) in
the blanking preceding the vertical sync pulse.
Parameter: VSPD.
Pulse Width The number of lines (Machine) or milliseconds (Time) of
the vertical sync pulse. Parameter: VSPW.
(green
calculator)
Indicates that the value in the field is calculated by the
Format Editor.
(red calculator) Indicates that the value in the field is calculated by the
Format Editor, and that the new value has replaced the
value previously in the field.
