Window scan start
WY=0 to 1079 for CV-A20CL

Window scan height
WH=1 to 1080 for CV-A20CL
WH=2 to 1080 for CV-A80CL
FVAL Period
* 1 : Strobe Delay Time
The duration from the trigger input to the Strobe signal output can be delayed.
* 2: Readout Begin Period
The Strobe signal is asynchronous in relation to the line rate. FVAL is output synchronous
to LVAL when the Strobe signal is changed from HIGH level to LOW level.
LVAL Period
The timing for LVAL period is the same as the timing for Continuous mode and Windowing.
Trigger minimum interval
The following timing chart explains the period required for new trigger input after the data is
output.
