3. Software considerations
Users of the CS82GC – 1 GHz under Windows 98/ME/NT require a special driver version (3.60.30), which
is supplied on the Gage Software Disk. Please note that the CompuScope 3.60.30 driver is a special release
and is not available through the standard install procedure. Instructions on locating the CompuScope
3.60.30 driver can be found in the Gage Software Disk readme, in the section titled: “Which CompuScope
drivers should be installed”.
Users of the CS82GC – 1 GHz under Windows 2000/XP can use the most recent CompuScope Win 2K/XP
drivers.

and the various SDKs, however, will not perceive the 1GHz version of the CS82GC as having
only 2 input ranges (one for Dual Channel Mode, one for Single Channel Mode). Users must therefore
ensure that they request the correct input ranges when operating the card, or risk seeing their data scaled by
the wrong factors (see Section 2 on previous page).
