Low Noise Prepolarized Microphone
378A04
-
The 378A04 is a matched system that is comprised of a high sensitivity microphone and a low noise preamplifier that contains a built-in filter that enables the free-field response to remain flat over a wide frequency range. The system requires a minimum of 4 mA and measures to 6.5 dBA (5.5 dBA typical) within a cost efficient, prepolarized (0V) design. PCB's model 378A04, the industry's first prepolarized low noise microphone and preamplifier system allows you to measure extremely low amplitudes. In the past this was only possible with externally polarized solutions. With a typical noise floor of 5.5dBA, this microphone system delivers all of the benefits commonly associated with prepolarized systems.

Noise Receiver Modules And Noise Switching Modules
MT7553 Series
-
Noise Parameters are the non-50Ω extensions of Noise Figure, and are an important modeling and model validation tool to understand how a device-undertest’s performance changes as a function of source impedance. Noise Parameter measurements are typically performedusing a Vector Network Analyzer (VNA) to measure the S-Parameters of the DUT, and a Noise Analyzer (either Noise Figure Analyzer NFA or Spectrum Analyzer SA) to measure the noise power of the DUT. Noise parameters are calculated from a combination of knownsource impedances, S-parameters and noise powers.

Environmental (Radiation) Monitoring System
Hawk® EMS
-
The Hawk® EMS is a wall or tripod-mounted radiation monitoring and alarm system designed for use with the Hawk® Radius dual sensor radiation probe. Each EMS System comes with a Hawk Radius Probe. The system is extremely energy efficient and can run for weeks on an internal 9 volt back-up battery if power fails. It is well suited for operating on a small solar panel, which is an optional accessory. The Hawk® EMS features two displays that show the radiation levels measured by each of the probe’s two detectors: the weatherized “pancake-style” Geiger-Mueller tube — which measures alpha (if configured for it), beta, low energy gamma, and x-radiation — and the energy-compensated gamma tube which measures penetrating gamma dose rate. The probe can be mounted next to the EMS system or outdoors, or in adjacent rooms on cables up to 100 ft in length. Standard cable is 3 meters in length. Optional signal booster can support cable lengths longer than 100 feet. Optionally the system can also be configured to share data on ethernet or wireless networks.
