7.1.1. Clock Select
With Clock Select two speeds can be selected, 15 MHz or 30 MHz.
The 15 MHz operation will limit the maximum line rate (scan rate) to 7 172 Hz. It is
recommended when a cable length of more than 20 metres is used or in applications where high
With Clock Select two speeds can be selected, 15 MHz or 30 MHz.
The 15 MHz operation will limit the maximum line rate (scan rate) to 7 172 Hz. It is
recommended when a cable length of more than 20 metres is used or in applications where high
RFI fields may be experienced.
7.1.2. Binning
With Binning set to 2048 the full resolution of the CCD sensors is 2048 pixels. If a higher
sensitivity is required, and a reduced resolution can be accepted, the binning function can be
selected by switching to 1024. As the readout section of the CCD sensor output, 2 adjacent
pixels are added and read out as one single pixel.
The STROBE frequency is divided by 2 when the camera is operated in 1024 binning mode.

7.1.3. Trigger Mode
With Trigger Mode to Internal, the camera is configured to generate the trigger pulse
internally. The Scan time and Shutter Time need to be configured for proper operation in this
mode. In External mode, the camera is configured to accept an EXT TRIG pulse.

7.1.4. Shutter/Scan Mode
With Internal trigger and Shutter/Scan Mode in Shutter mode, the camera will be set to expose
for a pre-defined period of time set by Shutter Time. The scan interval (or scan rate) is set by
Scan Time. In Scan mode, the exposure time is the same as the Scan time.
With Internal trigger and Shutter/Scan Mode in Shutter mode, the camera will be set to expose
for a pre-defined period of time set by Shutter Time. The scan interval (or scan rate) is set by
Scan Time. In Scan mode, the exposure time is the same as the Scan time.
With External trigger and Shutter/Scan Mode in Shutter mode, the exposure is equal to the
trigger low period. In Scan mode the exposure to the time interval between the external trigger
pulses.

7.1.5. Shutter/Scan Time
The Shutter/Scan Time controls the shutter time and scan time for internal trigger mode.
The range of setting for the Shutter Time is 1 µs to (Scan Time – 150 µs).
The range of Scan Time is 151 µs to 32.35 ms.
The Shutter/Scan Time controls the shutter time and scan time for internal trigger mode.
The range of setting for the Shutter Time is 1 µs to (Scan Time – 150 µs).
The range of Scan Time is 151 µs to 32.35 ms.
Example, if Scan Time is set to 300 µs the range of setting is up is 300 µs – 150 µs = 150 µs.
The Shutter/Scan Time control has no function in external trigger mode.
The Shutter/Scan Time control has no function in external trigger mode.
