FSPP
Frame Sync Pulse Polarity
Class
Format parameter setting - Synchronization
Description
Establishes the logic sense of the digital frame sync output. Setting polarity to one (1)
causes the leading edge of frame sync to be a low-to-high transition. Setting polarity to
zero (0) causes the leading edge of frame sync to be a high-to-low transition. The FSPP?
query returns the current polarity of FSPP.
Command syntax
FSPP
polarity
polarity
0 = active-low (negative going pulse)
1 = active-high (positive going pulse)
Query syntax
FSPP?
Query response
0 or 1
Other required
commands
To get a pulse, frame sync must first be enabled with the
FSPG
command. The
FMTU
command instructs the generator to use the new settings. The
ALLU
command updates
the hardware to the new settings and redraws the test image.
Example
FSPG 1
// Enable Frame Sync
FSPP 1
// Set for positive going pulse
FSPW 20
// Make the pulse 20 pixels wide
FSPG 300
// Pulse to occur 300 lines after
// the last line of active video
FMTU
// Update hardware to new settings
