Model 801GC, 801GF & 801GX¥Rev. A
EQUA EQUalization interval After vertical sync
pulse
Classification: Format parameter setting
Command Syntax: EQUA <lines>
Limits: <lines>
min = 0
max = number of lines after vertical sync before video
Query Syntax: EQUA?
Query Response: <lines>
Description: The EQUA command establishes the width of the equalization
interval after the vertical sync pulse in each field whenever a
serrated & 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 EQUA? query returns the current setting of EQUA.
Other Required Cmds: The FMTU command instructs the generator to use the new
setting. The ALLU command updates hardware to the new setting
and redraws the test image.
Example: EQUA 3 // Set post-equalization to 3
// lines in buffer
FMTU // Update hardware to current
// buffer contents
