Command Reference
VTOT
Vertical TOTal lines per frame
Class
Format parameter setting - Video resolution
Description
Establishes the total number of lines per frame. When interlacing (SCAN=2), VTOT must
be odd. The VTOT? query returns the current setting of VTOT.
The frame or picture refresh rate is equal to HRAT divided by VTOT.
The field or vertical rate is equal to the frame rate when SCAN = 1 (non-interlaced
operation).
The field or vertical rate is equal to twice the frame rate when SCAN = 2 (non-interlaced
operation).
Note: The current version of the firmware does not allow you to directly enter a specific
field or frame rate when setting up a format. If your test specifications call for a specific field,
frame or vertical refresh rate, enter suitable values for HRAT, SCAN and VTOT to give you
the desired rate.
