Description
Overview
The Keysight 346B is a broadband noise source ideal for general-purpose noise figure measurements in RF and microwave testing. Covering 10 MHz to 18 GHz, it provides higher ENR (15 dB) compared to the 346A, making it suitable for characterizing devices with higher noise figures. The low SWR design reduces measurement uncertainty caused by signal reflections.
Key Features
- Frequency range: 10 MHz to 18 GHz
- Nominal ENR: 15 dB (higher than 346A for high-noise-figure devices)
- VSWR: < 1.3:1 for low measurement uncertainty
- Multiple connector options available
- BNC (female) bias input
- Individually calibrated ENR values at specific frequencies
- Optional H01 for extended high ENR (21 dB typical)
- Optional H42 for Direct Broadcast Satellite (DBS) applications
Applications
- Noise figure characterization of high-noise-figure devices
- Calibration of noise figure measurement systems
- Testing of RF and microwave amplifiers and receivers
- Direct Broadcast Satellite (DBS) low noise block converter testing (with H42 option)
Specifications
| High Frequency (range) | 10GHz <= 20GHz |
| Low Frequency (range) | 1MHz <= 10MHz |
