346B/001 Noise Source, nominal ENR 15 dB

Configurations:

• (001) Type-N female[a] mating connector

Features:

• 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

The 346B 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 reduces a major source of measurement uncertainty, which are reflections of the test signals.

Other options to consider:

• Add H01 for high ENR (21 dB typical) to measure high noise figure devices
• Add H42 for measuring Direct Broadcast Satellite (DBS) low noise block converters.
