346A Noise Source, 10 MHz to 18 GHz, nominal ENR 6 dB
The Keysight 346A noise source (10 MHz to 18 GHz) with a 6dB ENR is designed especially for accurate characterization of input-impedance-sensitive devices...

HIGHLIGHTS
The Keysight 346A noise source is the ideal companion to Keysight's noise figure solutions. Since it is broadband (10 MHz to 18 GHz), it eliminates the necessity for several sources at different frequency bands. The low SWR of the noise source minimizes reflection of test signals, reducing measurement uncertainty. The very small change in reflection coefficient (<0.01) from ON to OFF is designed especially for accurate characterization of input-impedance-sensitive devices (like GaAsFETs and many UHF amplifiers).
- Frequency range: 10 MHz to 18 GHz
- VSWR: < 1.3:1
- Connectors: BNC (f) input bias / 3.5 mm (m)
- Low SWR for reducing noise figure measurement uncertainty
- Individually calibrated ENR values at specific frequencies
