6.2.7. LVAL synchronous accumulation

With LS=0, the accumulation will start synchronously with LVAL. The trigger pulse should be longer than 2 LVAL intervals, and the accumulation will then start at the first LVAL after the trigger leading edge. The exposure start delay will be up to 1 line. (Single channel 47.9 ∝sec. Dual 27.3 ∝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 0.5 L after the first LVAL after the trigger trailing edge. It results in up to 1 LVAL jitter.

In LVAL synchronous accumulation mode a new trigger can start a new exposure during the previous frame read out, but the exposure may not be finished before the frame is read out. It makes it possible to have a trigger rate close to the frame rate. (1 FVAL + 3 LVAL).

Important notes on using this mode.

In LVAL synchronous PWC mode exposure jitter up to 1 LVAL can be the result, if the trigger trailing edge is not synchronized to LVAL.
