PI-MTE series cameras do not incorporate an internal shutter. In addition, only
full-frame CCDs (as opposed to frame-transfer CCDs) are available at this writing

.
Because PI-MTE cameras do not incorporate an internal shutter, some signal may
accumulate on the array while it is being readout. This continuous exposure of the array
during readout may result in some smearing. However, exposures that are significantly
longer than the readout time can be performed without a shutter, as the amount of
smearing will be low.
If smearing or other factors require a shutter, the NOT SCAN or the SHUTTER signal at
the ST-133's SCAN output can be used to control a customer-supplied external x-ray
shutter. By using one of the signals to synchronize the shutter operation with exposure,
the CCD can be read out in darkness. Alternatively, the x-ray source can be interrupted
elsewhere in the system while readout is taking place.
