11.5.3 Examples
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
active
analog input to 16-bit output, without SAV/EAV codes,
Y on I port, C
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
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
