26-01167 Digital Phase Noise Analyzer_Specifications-DNA-Hati.docx

This file contains technical specifications for a Digital Frequency Stability and Phase Noise Analyzer required by the National Institute of Standards and Technology (NIST) under solicitation number NB688000-26-01167. The NIST Acquisition Management Division, Team E-Boulder issued this requirement as a Request for Quotation (RFQ) set aside exclusively for small businesses. The analyzer must support carrier frequencies from 2 MHz to at least 400 MHz for both Device Under Test and Reference inputs, with RF input levels ranging from -10 dBm or lower to +20 dBm or higher, and 50-ohm nominal input impedance.

The equipment must feature a Digital Phase Noise Extraction engine capable of measuring without a Phase Locked Loop and support non-harmonic reference capability, allowing the DUT and reference to operate at different frequencies without external hardware. The analyzer must provide phase noise sensitivity with minimum offset analysis from 1 mHz to 1 MHz or higher, and achieve residual phase noise floors at 100 MHz carrier of -121 dBc/Hz at 1 Hz offset, -178 dBc/Hz at 10 kHz offset, and -194 dBc/Hz at 10 MHz offset. The "Full" version must include integrated ultra-low noise internal reference oscillators (OCXOs) for autonomous operation, spurious detection capability, and inherent computation of Allan Variance, Overlapped Allan Variance, Hadamard Variance, and Overlapped Hadamard Variance. The unit must be a benchtop chassis with maximum 4U height compatible with 19-inch racks and include a Gigabit Ethernet interface for remote control and data transfer. Residual Allan Deviation specifications require less than 7E-14 at 1 second tau and less than 5E-16 at 1000 second tau for the 5 MHz to 400 MHz range.
