This is a Recommendation and Determination to Solicit from One Source or Brand Name document from NASA's Shared Services Center, dated January 15, 2017.

NASA seeks to procure a Precision Power Analyzer for Power Management Distribution Technology Development on a sole-source basis from Yokogawa. The total estimated cost is redacted, with a lead-time for delivery of 12 weeks ARO. The justification for single-source procurement centers on the Yokogawa Precision Power Analyzer's unique technical capabilities required for NASA's Power Management Distribution Technology Development activities while maintaining compatibility with existing laboratory instrumentation. The required power analyzer must meet minimum specifications including 0.03% AC power accuracy, 10 MS/s sampling rate, 18-bit ADCs, a minimum of four channels, current sensing capability compatible with 200A RMS, 16 ppm total accuracy, 1 MHz bandwidth, and expansion slots for future improvements. The specific Yokogawa equipment identified includes one WT5000 Precision Power Analyzer, four 760903 Current Sensor Elements, four M1114FR Current Transducers (300ADC), and four M1114GA Current Transducer Cables (5M). NASA determined that alternative manufacturers' equipment would result in incompatibility with existing laboratory hardware, requiring modification or replacement of supporting equipment, creating duplicate hardware and test configurations, introducing unnecessary integration and configuration efforts, potentially delaying testing and program schedules, and possibly compromising measurement accuracy and capabilities essential to the development program.
