This Windows 98/2000/XP software is used to operate the SPS-200 FTIR. It is a LabView based application but compiled such that the user does not require the LabView Development Environment to operate it. The Basic SPS-200 system already has this software included. This option is for former SPS-200 system owners who wish to upgrade their software to the latest features. This basis SPS-200 software upgrade only supports the standard step and scan mode and not the rapid scan mode. The rapid scan mode is available separately as corresponding hardware is also required.
