Computer Aided Test Set I and II (CATS I, II) are computer test systems designed to assisted field technicians in the troubleshooting and calibration of Soviet SAM-7 and SAM-9 IR seekers. These systems were used extensively during wargames and simulations years past. These systems were built into commercial vans that allowed for transport to a given operational theater.
The first CATS guided the missile technician through the process of disassembly, and sub-system elimination. Once this query is completed, the CATS would have the operator connect stimulus and measurement probes to the sub-system and measure the various parameters. If these measurements fit within the guidelines, then another series of tests would be conducted until the problem was identified.

The success of the first CATS working with the SAM-07 lead to the second development for the CATS II that was used with the SAM-09 seekers. In this configuration we were not only able measure pass/fail parameters, but also degradation of performance for each given seeker. This was done by first characterizing each seeker in a known "good" state of operation. Afterwards this data can be used to compare with future field evaluations and allow for a more accurate diagnosis. These systems operated for years at White Sands MICOM facility.
