***** Sole source determination is based on the need to procure a portable RTDS that can be used at a desktop or during trips to other offices or laboratories.
The RTDS must be compatible with NIST's current RTDS, an OP6500 manufactured by Opal-RT Technologies. No other manufacturer offers a portable RTDS that is compatible with the OP6500. Furthermore, Opal RT has no authorized resellers in North America.
