ESCRIPTION
Micronetics' line of full band noise
sources are specially designed for easy
integration into microwave systems.
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 Output
• Waveguide Isolator
Each noise source is calibrated to the
output port so no external deembedding
of calibration data is necessary. In addi-
tion to the RF output choices, there are
also different packages available to
meet a wide range of mechanical con-
straints.

ESIGN
:
The heart of these noise sources is a small chip and wire hermetic noise module.
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.

SSURANCE
:
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 con-
formance is supplied with each unit.
