Description
Overview
The Keysight 346C is a broadband noise source designed for accurate noise figure measurements across RF and microwave applications. It covers 10 MHz to 26.5 GHz, making it suitable for characterizing the gain and noise performance of various devices under test without requiring multiple sources at different frequency bands.
Key Features
- Broadband frequency range: 10 MHz to 26.5 GHz
- Dual ENR levels: 16 dB (10 MHz–12 GHz) and 17 dB (12 GHz–26.5 GHz)
- Low VSWR less than 1.35:1 reduces measurement uncertainty
- BNC female connector for power input and APC-3.5 male output connector
- Individually calibrated ENR values at specific frequencies
Applications
- Noise figure characterization of amplifiers and components
- Device under test (DUT) noise and gain measurements
- System noise figure verification in RF and microwave systems
Specifications
| High Frequency (range) | 20GHz <= 50GHz |
| Low Frequency (range) | 1MHz <= 10MHz |
