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.

CAT-5 Cable Equalizers
Analog Devices high speed, differential receivers and CAT-5 cable equalizers compensate for the transmission losses of UTP and coaxial cables up to 300 meters in length. Our design techniques for products such as the AD8123 optimize performance for low noise, short-to-medium range applications, while also providing the high gain bandwidth required for long cable equalizations. Various gain stages are summed together to best approximate the inverse frequency response of the cable. Logic circuitry controls the gain functions of the individual stages so that the lowest noise can be achieved at short-to-medium cable lengths.

Power modules
G.R.A.S. Sound & Vibration A/S
It provides polarization voltage for the transducer, ensuring that the microphone gets the charging voltage it needs.It provides supply voltage for the microphone preamplifier. The preamplifier acts as a unity gain impedance converter. It provides a certain amount of line drive capability by providing a low output impedance and output current, making it possible to transmit the signal from the transducer to the Power Module without significant degradation.A power module can provide amplification or attenuation to the signal, thus making it possible to fine tune the measurement chain to the signals being measured and the hardware being used.Selectable filters make it possible to exclude unwanted noise from the measurement, e.g. wind induced noise from outdoor measurements.Overload detection makes it possible to validate the measurements and is a useful tool in monitoring setups.When a Power Module with gain is used, you can use longer cables because of the power module's ability to deliver current.A Power module introduces electrical isolation
