346B/346B-100

346B/346B-100 is a noise source. Since it is broadband, 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. Add special option H01 for high ENR (21 dB typical) to measure high noise figure devices, or option H42 for measuring Direct Broadcast Satellite (DBS) low noise block converters.

• Frequency range from 10MHz to 18GHz
• VSWR is less than 1.3:1
• BNC female input and APC-3.5 male output connector
• Low SWR for reducing noise figure measurement uncertainty
• Individually calibrated ENR values at specific frequencies
