Class Format parameter setting - synchronization
Description Establishes the width of the equalization interval before the vertical sync pulse in each
field whenever a serrated and equalized sync type is selected via either ASCT or DSCT
commands and selected via the SSST command. If the type specified for the selected
sync signal is one of the CCIR types, then the actual equalization interval output by the
generator will be 0.5 lines shorter than the whole number specified. The EQUB? query
returns the current setting of EQUB.
Command syntax EQUB lines
