Collection
The 96-Lane Scan mode uses 480 collection channels per scan, up
from 388 in an XL Scan mode. This provides a 5x oversampling for

Increased
Position-Based
Due to the increased demand for positional accuracy of the detection
optics, a new integration scheme is used. Previously, a given time was

given to each channel, before reading the CCD camera and switching to

the next channel. This release of firmware introduces position-based
CCD integration, where predetermined stage positions determine when
to switch.
Expanded Scan
The 96-Lane Scan mode uses a larger scan region to accommodate
the increased comb size. The stage travels farther towards the edge on
Region
each side, and accelerates at a faster pace as it reenters the scan
region. This offsets the increased number of collection channels, so that
the integration time per channel remains approximately that of an XL
scan. As a result, there is no loss of sensitivity for a 96-lane scan
compared to an XL scan.
The instrument firmware automatically adjusts the size of the read
region according to the selected scan mode. Users who wish to
prevent the firmware from redefining the size of the scan window may
be provided with special module files for this purpose.
