Millimeter-Wave Noise Source, R-band, 26.5 to 40 GHz
R347B
-
The Keysight R347B noise source covers a 26.5 to 40 GHz frequency range. This waveguide noise source allows you to make accurate and convenient noise figure measurements on millimeter-wave devices. The R347B provides highly precise broadband noise at the input of the system or component under test. The noise figure meter then processes the ON/OFF ratio of noise power present in the system IF, and provides an accurate reading of noise figure and gain. The R347B noise source has remarkable ENR stability over time, which allows longer recalibration cycles and more accurate noise figure measurements.

Noise Source, 10 MHz to 18 GHz, nominal ENR 15 dB
346B
-
The Keysight 346B noise source is the ideal companion to Keysight's noise figure solutions. Since it is broadband (10 MHz to 18 GHz), it eliminates the necessity for several sources at different frequency bands. The low SWR of the noise source reduces a major source of measurement uncertainty; reflections of test signals. The 346B's high ENR, low SWR, and variety of connectors make it a general-purpose noise source. Add special option H01 for high ENR (21 dB typical) to measure high noise figure devices, or option H42 for measuring Direct Broadcast Satellite (DBS) low noise block converters.

Environmental Noise Monitors
-
Noise is one of the most complained about aspects of the environment, as not only does it have the potential to affect quality of life, it can also be difficult to monitor and therefore control. This type of noise is generally called environmental noise. There are many man-made sources of environmental noise, such as wind turbines, industrial sites, roads and traffic etc. If you are looking for equipment to measure noise in the workplace, look at sound level meters.

Low Phase Noise Amplifiers
-
Low Phase Noise amplifiers are critical for many applications requiring high signal integrity. This is especially relevant in instrumentation, defense, and telecommunication applications where low phase noise amplifiers are becoming increasingly important as the oscillators improve. Phase noise is described as the close-in noise to the carrier that can often appear as jitter on a clock signal. Analog Devices offers a large portfolio of low phase noise amplifiers to meet a variety of requirements in the LO network, receiver, as well as in the transmitter. Our portfolio supports a wide range of power levels and frequencies to provide the right solution for the given application.
