346C/H01 includes APC 3.5 (m) connector with 21 dB nominal ENR.

• Frequency range: 10 MHz to 26.5 GHz
• Nominal ENR 21 dB
• VSWR: < 1.35:1
• Connectors: BNC (f) input bias / 3.5 mm (m)
• Low SWR for reducing noise figure measurement uncertainty
• Individually calibrated ENR values at specific frequencies

Keysight 346C noise source is the ideal companion to Keysight's noise figure solutions. Since it is broadband (10 MHz to 26.5 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; reflections of test signals.
