Product Overview
Noise sources generate random, continuous spectral signals that provide noise power standards for noise figure measurements. With over 30 years of experience in noise figure testing, Ceyear Instruments developed the 1661X series of noise sources, which have stable output noise power and uniform power spectral density. These sources can greatly enhance the accuracy of noise figure testing. The series includes 22 models of standard noise sources (16613) and intelligent noise sources (16614/16615), which support three types of drive interfaces: BNC, I²C, and USB.
They have a wide bandwidth, covering 10 MHz to 110 GHz. The products have the advantages of a small VSWR of the output port, good output SNR flatness, and more. These products can be used to set up a noise figure test system with various noise fig ure measurement instruments. They can also be used independently as a calibration source.
The 16613 series standard noise sources cover frequencies from 10 MHz to 18, 26.5, 40, 50, 67, and 110 GHz. The series incl udes eight models: the 16613DA DB EA EB FB HB LC and P. They adopt the international standard +28 V voltage drivers and BNC negative head driver interface for strong compatibility.

The 16614 series of intelligent noise sources covers 10 MHz to 18, 26.5, 40, 50, and 67 GHz and includes seven models: 16614DA , 16614DB, 16614EA, 16614EB, 16614FB, 16614HB, and 16614LC. These models adopt I²C bus technology and electronically store the ultra noise ratio. They also have a buil t in digital temperature sensor that automatically loads the ultra noise ratio after connecting to a noise figure analyzer. The real time detection of the ambient temperature improves the measurement speed and accuracy.

The 16615 series intelligent noise source frequency covers 10 MHz to 18, 26.5, 40, 50, and 67 GHz. It includes seven models: 16615DA, 16615DB, 16615EA, 16615EB, 16615FB, 16615HB, and 16615LC. It has a USB interface design that is more in line with multi scenario applications. It is compatibl e with the USB TMC protocol and has electronic storage of an ultra noise ratio. It has a built in digital temperature sensor and can be easily accessed to support Windows and Linux test instruments. It can also be connected to a computer for program contro lled use.

Main Features
- Wide frequency coverage and flexible band selection, excellent SNR flatness and selectable SNR parameters
- Supports a wide range of noise figure measurement instruments. The USB noise source can also be connected to a computer for programmed use
- The 16614/16615 Series Intelligent Noise Sources are plug-and-play with electronic storage of SNR data
- The 16614/16615 Series Intelligent Noise Sources have built-in digital temperature sensors that detect the ambient temperature in real time
Wide frequency coverage and flexible band selection
The noise source is characterized by its wide frequency coverage, flexible frequency band selection, excellent ultra-noise ratio flatness, and selectable ultra-noise ratio size. These features provide an optimal noise power standard for measuring the noise coefficients of the parts under test in different frequency bands and gain ranges.

Supports a wide range of noise figure measurement instruments
The Series 16615 USB Intelligent Noise Sources can be paired with Ceyear's TianHeng Star series of noise factor analyzers, vector network analyzers, and signal/spectrum analyzers; the 4082 and 4052 series of signal/spectrum analyzers; and other hosts. They can also be paired with a computer for programmed use.
Intelligent Noise Sources are plug and play with electronic storage of SNR data
The 16614/16615 series noise sources support an automatic intelligent identification function and plug and play capability. They have built in electronic memory that stores frequency and ultra noise ratio data pairs. After connecting them to noise coefficient measurement instruments, the ultra noise ratio of the noise sources can be automatically loaded into the noise coefficient measurement instrument's ultra noise ratio table. This improves measurement speed.

Intelligent Noise Sources have built in digital temperature sensors
The 16614/16615 series of intelligent noise sources has a built in digital temperature se nsor that detects changes in ambient temperature in real time. This sensor is used for temperature
correction of noise figure measurements, thereby improving measurement accuracy.
