Type RAS-1 -
National RF, Inc
Called the RAS-1, the receiver is designed for ultra low and very low frequency scientific research work, including the exploration of low frequency emissions due to seismic and earth-quake activity, study of atmospheric phenomenon such as "whistlers", and low frequency Sudden Ionospheric Disturbance (SID) and electromagnetics phenomenon. The RAS-1 will receive signals from under 200 Hz. To over 250 KHz in both narrow bandwidth modes as well as broad badnwidth reception.

LFR -
Powertek LLC
The LFR ac current probe has been designed to have market leading low frequency performance, meaning low phase shift and low noise. This compact, low cost, clip-around probe is both flexible and dual-range, and is optimized to give minimal phase measurement error at frequencies from 45Hz to 20kHz and have a very low noise floor.

Alpha Cabin -
Autoneum Holding AG
The Alpha Cabin has been especially designed for the measurement of acoustic absorption properties of materials and components used for the noise insulation of vehicles. The Alpha Cabin is significantly smaller than normal reverberation rooms and therefore ideally suited to use within limited space capacities. The acoustic absorption of the Alpha Cabin itself is also very low: Thanks to the high level of sound insulation, background noise in the frequency range of interest is kept to a minimum.

Schwarzbeck Mess Elektronik
The broadband horn antennas BBHA 9120 offer a very low SWR in their nominal frequency range and a very broad bandwidth. The gain increases with frequency up to approx. 21 dBi, depending on the horn's size and shape. The increasing gain with frequency helps to compensate cable losses. The BBHA 9120 series is suitable for both, transmission and receiving applications. The max. allowed Input Power is only limited by the female N-connector. The detailed manual of the calibrated test antennas includes Gain, Antenna Factor, SWR and Directional Patterns. The antenna is mounted with the 22 mm tube, equipped with a Index Ring for quick changes of polarisation without using tools.

Smiths Interconnect
Switched Filter Banks typically include multiple filter topologies, including PIN diode and MMIC switch sub-circuits to achieve operational bandwidths of greater than 3 octaves. Pin Diode Based Switched Filter Banks provide the highest level of signal isolation, higher operating power levels, and lower insertion loss and achieve switching speeds of < 40 nanoseconds. GaAs MMIC Based Switched Filter Banks provide switching times as low as 10 nanoseconds with very low power consumption and have the inherent advantage of supporting multi-octave frequency bands with extremely low power consumption.

MISS -
BioAge s.r.l.
The Micro Smart System is one of the many autonomous systems with very low consumption designed by BioAge. The system is characterized by autonomous operation with very low energy consumption thanks to its operation in "Energy Harvesting" which allows to exploit the power supply from a micro solar panel with which each sensor is equipped. Furthermore, these systems are equipped with radio frequency communication able to remotely transmit the information acquired by the sensors on board, it is therefore possible to create a network of sensors, operating autonomously and with a very high autonomy thanks to solar energy.
