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.
