Noise Figure Measurements With Vector Correction
S96029B
-
This software application enables high-accuracy noise figure and noise-power measurements of amplifiers. It utilizes Keysight’s unique vector-source-correction technique, which uses a source-impedance tuner to remove the effects of imperfect system-source match. This approach yields accuracy that surpasses that provided by the Y-factor method and other cold-source implementations, especially for in-fixture, on-wafer, and automated-test environments. A scalar-calibrated method is also available that offers less accuracy but is faster and does not require an impedance tuner.

Becker Nachrichtentechnik GmbH
Software-Defined Radio (SDR) is an attractive approach for mobile communication architectures in the development and evaluation phase for a rapid prototyping on a flexible platform. SDRs support a wide frequency range. However, for practical use in the field the HF properties are insufficient. The transmit power is limited to a 2-digit mW value. Dedicated filters are required for an effective suppression of out-of-band signals and to improve the noise figure of the receiver chain. Extending SDRs with application-specific RF-frontends achieves optimal RF performance in the field.

1. Erbium-doped Fiber Amplifier, due to the multiple cascades and the accumulation of noise caused by spontaneous emission, will reduce the system CNR greatly and thus it will limit the transmission capacity and distance of the system. Raman Amplifier is a newly designed fiber amplifier based on Stimulated Raman Scattering (SRS) effect. Raman amplifier is considered as the core technology of new generation DWDM fiber over-long communication. Compared with Erbium-Doped Fiber Amplifier, Raman amplifier has the advantage of low Noise Figure (NF), wider gain bandwidth, flexible gain spectral region and stable temperature. It is the only device that can operate in 1300~1600 nm.
