346A/346A-004

346A/346A-004 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 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 from 10MHz to 18GHz
• VSWR is less than 1.3:1
• BNC female input and Type N female output connector
• Low SWR for reducing noise figure measurement uncertainty
• Individually calibrated ENR values at specific frequencies
