Exposure Modes in Detail
Mode 2: Internally Programmable Frame Rate and Exposure Time
(Default)
The parameter being programmed (that is, frame rate or exposure time) will be the
driving factor so that when setting the frame rate, exposure time will decrease, if
necessary, to accommodate the new frame rate. In reverse, the frame rate is decreased, if
necessary, when the exposure time entered is greater than the frame period.
Note:
The
camera
will not set frame periods shorter than the readout period.
If a frame rate is set (using the
ssf
command) to a time shorter than the readout period,
the camera will automatically adjust the frame period to be at least as long as the readout
time.
Mode 4: Smart EXSYNC, External Frame Rate and Exposure Time
In this mode, EXSYNC sets both the frame period and the exposure time. The rising edge
of EXSYNC marks the beginning of the exposure and the falling edge initiates readout.
There is a 100
μ
s delay between the trigger and the start of the exposure. The minimum
delay between consecutive exposure times is 150
μ
s. The minimum pulse width (exposure
time) is 40
μ
s.
