Keysight E8257D Signal Generator

Background
The National Aeronautics and Space Administration (NASA) is issuing this Request for Quotation (RFQ) for the procurement of a refurbished Keysight E8257D Signal Generator.

The goal of this contract is to acquire high-speed signal generation equipment to support NASA's mission objectives at the Stennis Space Center.

Work Details
The contract involves the procurement of a refurbished Keysight E8257D PSG Analog Signal Generator with the following specifications:
- Model: Keysight E8257D PSG Analog Signal Generator
- Configuration: 520 / 1E1 / 1EU / UNT
- Frequency Range: 250 kHz to 20 GHz
- Frequency Resolution: 0.001 Hz
- Switching Speed: ~7–10 ms (typical)
- Output Power Range: –135 dBm to +7 dBm (with step attenuator)
- Level Resolution: 0.01 dB
- Accuracy: ±1.0 to ±1.5 dB (typical, frequency dependent)
- Spectral Purity:
- Phase Noise: ~–126 dBc/Hz @ 10 kHz offset (10 GHz carrier)
- Harmonics: ≤ –55 dBc
- Non-harmonics (spurious): ≤ –80 dBc
- Modulation Options (Option UNT):
- AM: Depth from 0 to ~90%, Rate from DC to ~100 kHz
- FM: Wide deviation capability, Rate from DC to ~10 MHz
- PM: Wide deviation capability with internal LF modulation source included.

Period of Performance
Estimated delivery date is within 4 weeks upon receipt of order.

Place of Performance
Products will be delivered to NASA Armstrong Flight Research Center, Bldg 4876 Warehouse #6, Lilly Drive, Edwards, CA 93523.

Incumbent Analysis (see Incumbents section for more detail)
This opportunity appears to have a confirmed incumbent and/or closely related prior contract based on award 80NSSC25PA700, awarded to Measurements International for a “MI SYSTEM UPGRADE / REPLACEMENT FOR GRC CAL LAB” valued at $153,900 (04/07/25–02/26/26). The current RFQ similarly seeks procurement of a refurbished Keysight E8257D signal generator for NASA calibration/lab support at a NASA facility, suggesting the prior work likely involved upgrading or replacing measurement/signal generation equipment used in the same type of calibration environment.
