They feature rugged construction with excellent long-term stability. Configurable to your requirements: Micronetics full band noise sources are based on a coaxial design as the base part. As standard options, noise sources can be ordered with either • Coaxial Isolator • Waveguide Isolator Each noise source is calibrated to the output port so no external deembedding of calibration data is necessary. In addition to the RF output choices, there are also different packages available to meet a wide range of mechanical constraints.

This is embedded in the housing with a precision launch to the coaxial jack. This design gives is much more stable and rugged than traditional coaxial noise sources which rely on pill packaged diodes and beryllium copper bellow assemblies which are not only are less reliable, but use hazardous materials. Calibration and Quality Assurance: Each noise source is accurately calibrated using a reference noise source traceable to NIST/NPL Calibration data consists of 5 calibration points across the full-band. Data is supplied as a print out. Special calibration data can also be supplied upon request (consult factory). Standard choices are: • More calibration points across the spectrum • Special discrete calibration frequencies • Data supplied in soft format as screen capture or text file on floppy or CD-ROM. In addition to the calibration data, a certificate of calibration and a certificate of conformance is supplied with each unit. | | | | | | | | | | | | | | | | | | Model | Frequency | Waveguide | | | | RFN25C1 | 3.95 to 5.85 GHz | WR-187 | | | | RFN25C2 | 5.85 to 8.20 GHz | WR-137 | | | | RFN25X | 8.20 to 12.4 GHz | WR-90 | | | | RFN25Ku | 12.4 to 18.0 GHz | WR-62 | | | | RFN25K | 18.0 to 26.5 GHz | WR-42 | | | | NS2640 | 26.5 to 40.0 GHz | WR-28 | | | | | | | | | | | | | | | | | | NOISE PRODUCTS | | | | | | | | | | | | | | MICRONETICS / 26 HAMPSHIRE DRIVE / HUDSON, NH 03051 / TEL: 603-883-2900 / FAX: 603-882-8987 | | WEB: WWW.MICRONETICS.COM | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
