Scaler source and reference events
analog input to 8-bit I port output, with
SAV/EAV codes, 8-bit serial byte stream
decoder output at X port; acquisition trigger
at falling edge vertical and rising edge
horizontal reference signal; H and V gates on
IGPH and IGPV, IGP0 = VBI sliced data flag,
IGP1 = FIFO almost full, level
qualifier logic 1 active
analog input to 16-bit output, without
SAV/EAV codes, Y on I port, C
H port and decoder output at X port;
acquisition trigger at falling edge vertical and
rising edge horizontal reference signal;
H and V-pulses on IGPH and IGPV, output
FID on IGP0, IGP1 fixed to logic 1, IDQ
qualifier logic 0 active
X port input 8-bit with SAV/EAV codes, no
reference signals on XRH and XRV, XCLK as
gated clock; field detection and acquisition
trigger on different events; acquisition
triggers at rising edge vertical and rising
edge horizontal; I port output 8-bit with
SAV/EAV codes like example number 1
X port and H port for 16-bit Y-C
input (if no 16-bit output selected);
XRH and XRV as references; field detection
and acquisition trigger at falling edge vertical
and rising edge horizontal; I port output 8-bit
with SAV/EAV codes, but Y only output
