Keysight / Agilent 346B Noise Source
The Keysight 346B (Agilent) Noise Source is an essential tool for enhancing the accuracy of noise figure measurements in a wide range of applications. Its broad frequency range of 10 MHz to 18 GHz eliminates the need for multiple noise sources, providing you with a reliable solution for testing across various frequency bands.
Designed to minimize measurement uncertainty, the Keysight 346B features a low SWR (Standing Wave Ratio) that significantly reduces reflections in test signals, a common source of error in noise figure assessments. With its high ENR (Excess Noise Ratio) values and versatile connectivity options, this noise source stands out as a go-to device for engineers and technicians alike.
Key Features and Specifications:
- Low SWR: Reduces noise figure (NF) measurement uncertainty, allowing for more accurate results.
- Individually Calibrated ENR Values: Enhances measurement accuracy at specific frequencies.
- Broad Frequency Range: 10 MHz to 18 GHz, for comprehensive application across various tests.
- VSWR: Less than 1.3:1, ensuring minimal signal reflections.
- Connectors: BNC (female) input bias / 3.5 mm (male) for versatile compatibility.
For enhanced performance, consider adding special option H01, which provides high ENR (typical 21 dB) for measuring high noise figure devices, or option H42 specifically designed for testing Direct Broadcast Satellite (DBS) low noise block converters.
