The U.S. Army TMDE Activity (USATA) has a requirement to purchase one Dual Bridge or equivalent unit due to obsolescence and aging of existing test equipment and standards. The new equipment will provide accuracy and stability in resistance measurements that shall be delivered to USATA?s Army Physical Standards Labs located at Building 5435, Fowler Road Redstone Arsenal. The new Dual Bridge or equivalent unit shall include the following: • High Resistance Coaxial Matrix Scanner: the Army requires system continuity in measurement architecture between current and upgraded scanners. The obsolesced 20 channel scanner utilizes coaxial relays that are not employed in any other matrix scanner aside from upgraded 10 channel scanners. (Required Quantity of 2) • 1000Vdc Programable Voltage sources (Required Quantity of 2.) • Input signal interface/Electrometer: (Required Quantity of 1.) • 10M?-1T? Temperature Stabilized High Resistance Standard: Upgrade existing aging standard. (Required Quantity of 1.) • Air Baths: The requirement air baths are to account for the variation in sizes of resistance standards that the Army supports such as High Resistance decade boxes and high resistance transfer standards that are much larger than single value resistance standards. (Required Quantity of 2.) • Equipment Rack: The rack is an accessory that is desired to aid in portability of the system and to maintain/ protect the integrity of sensitive connections. The Army’s Dual Source High Resistance Bridge or equal to parts does not require an EMI shielded rack and based on historical measurement data it is not a requirement. (Required quantity of 1.)
