About this file

This is a Statement of Work for NASA Langley Research Center's procurement of specialized electrical components for the Remote Acquisition Data System (RADS) at the 31" Mach 10 tunnel. The contractor is required to supply four specific component types: a Quad Bridge/Dynamic Strain Conditioner (Part No. 28144-HP4F/LP4FP-HC14-WL) with 8-pole band-pass filters, programmable bridge configurations, and extended amplifier bandwidth to 1.5 MHz; an 8-channel 8-pole band-pass filter/amplifier (Part No. 28608B-HP4F/LP4FP) with high-pass and low-pass filters; test adapters for excitation and factory acceptance testing (Part No. 28144-TEST-ADAPTER) with two adapters per card recommended; and replacement fans for the 28000 chassis (Part No. A9766G11).

All components must be delivered to NASA Langley Research Center at 4 South Marvin Street, Hampton, VA 23681 by August 14, 2026. The SOW specifies detailed technical characteristics for each component, including programmable options for bridge configuration, completion values, and calibration capabilities. The test adapter specification indicates that two units per card are recommended to complete factory acceptance testing procedures.
