8.5.2. LVAL a-synchronous accumulation
In LVAL a-synchronous mode, the accumulation will start immediately after the trigger leading
edge. The exposure start delay is 9.7
μ
sec. (In V-binning mode, this delay will be 39.7
μ
sec)
In EPS mode the exposure stops 0.5 L after the selected shutter time, (in number of LVAL).
In PWC mode the exposure stops 29.7
μ
sec after the trigger trailing edge.
A new trigger must not be applied before the previous frame is read out. (FVAL is low).
Minimum trigger interval
≥
(exposure time + 1 FVAL + 1 LVAL). (EPS mode)
