Ceyear has introduced the new 16613/16614/16615 Series Noise Sources, designed for RF, microwave and mmWave noise figure measurement applications. The product family covers a wide frequency range from 10 MHz up to 110 GHz and includes standard as well as intelligent noise source models with BNC, I²C and USB drive interfaces.
Noise sources are used to generate random, continuous spectral signals that serve as noise power standards for noise figure measurements. With stable output noise power, uniform spectral density and multiple frequency/SNR configurations, the Ceyear 16613/16614/16615 Series can be used with noise figure analyzers, signal and spectrum analyzers, vector network analyzers and PC-controlled test systems.
Series Overview: 16613 vs 16614 vs 16615
The new Ceyear noise source family is divided into three main series. Each series is designed for a different type of measurement setup and control interface.
| Series | Interface Type | Best For |
|---|---|---|
| 16613 Series | Standard BNC driver interface | Traditional noise figure measurement systems requiring +28 V BNC drive compatibility |
| 16614 Series | I²C bus driver interface | Intelligent instrument-controlled setups with electronic SNR data storage |
| 16615 Series | USB bus driver interface | Automated test systems, PC-controlled measurements and flexible laboratory use |
The 16613 Series is the standard noise source line. It covers frequencies up to 110 GHz and is suitable for conventional measurement systems using a BNC driver interface.
The 16614 Series adds intelligent functionality through an I²C bus interface. These models can electronically store SNR data and support automatic identification when connected to compatible measurement instruments.
The 16615 Series is the USB version, intended for modern automated and PC-controlled test environments. It supports USB-based communication and can be used with Windows and Linux test systems.
What Are Noise Sources Used For?
Noise sources are essential accessories for noise figure and noise factor measurements. They provide a known noise power reference that allows engineers to evaluate the performance of RF and microwave components such as amplifiers, receivers, converters and other devices under test.
In practical measurement systems, a noise source can be used together with:
- noise figure analyzers;
- signal and spectrum analyzers;
- vector network analyzers;
- automated RF test systems;
- PC-controlled measurement setups.
The Ceyear 16613/16614/16615 Series can also be used independently as a calibration source in suitable RF and microwave test environments.
Key Features
The Ceyear 16613/16614/16615 Series Noise Sources offer a combination of wide frequency coverage, flexible model selection and intelligent data handling in the 16614 and 16615 series.
Main advantages include:
- wide frequency coverage from 10 MHz to 110 GHz;
- multiple frequency bands: 18 GHz, 26.5 GHz, 40 GHz, 50 GHz, 67 GHz and 110 GHz;
- selectable SNR ranges for different measurement requirements;
- low output port VSWR;
- stable output noise power;
- good SNR flatness;
- standard BNC, I²C and USB interface options;
- plug-and-play support for intelligent models;
- electronic storage of SNR data in the 16614 and 16615 series;
- built-in digital temperature sensors in intelligent models.
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.
Where to Buy
The Ceyear 16613/16614/16615 Series Noise Sources are now available to order from SEA Components, the official Ceyear sales partner in the European Union.
