IGPH is a H-gate signal, framing the scaler output
IGPH is an extended H-gate (framing H-gate during scaler output and scaler
input H-reference outside the scaler window)
IGPH is a horizontal trigger pulse, on active going edge of H-gate
IGPH is a horizontal trigger pulse, on active going edge of extended H-gate
IGPV is a V-gate signal, framing scaled output lines
IGPV is the V-reference signal from scaler input
IGPV is a vertical trigger pulse, derived from V-gate
IGPV is a vertical trigger pulse derived from input V-reference
