Vivarium Rooms
Darwin Chambers Company ALAAC, OLAW, USDA, and NIH-compliant Vivarium Rooms are designed for maximum value, sustainability, and conformance with applicable standards. We have over a decade of experience in working with researchers to provide humane and often precise conditions to meet their unique and specific needs. Vivariums are commonly defined as a place, such as a in laboratory, where live animals and/or plants are kept under conditions simulating a natural environment. Often, these contain both plants and animals, within a micro-ecosystem, often with controlled stability or controlled change of environmental variables. We offer various surface finishes, including all stainless steel, which are easy to maintain and may be sterilized to cleanroom standards. Compartmentalized enlosures are offered, which are modular and reconfigurable. Our rooms will accommodate plants as needed (we also provide plant growth chambers), and we offer control of humidification in conformance with current ALAAC mandates, sufficient air exchanges, available HEPA filtration of intake and/or exhaust air, standard screened equipment hous- ings, and other such considerations.

Large-size Hybrid Reverberation / Anechoic Chamber
F-Series
The F large-size hybrid Reverberation/Anechoic Chamber represents the most versatile OTA test system in the market today. With the same unique test features of their E Series RC counterparts, the F-Series can also test large form-factor devices under test (DUTs) like laptops, large TV sets, solar and trash compactors, drones, fridges or washing and vending machines, among others. With up to 16x16, 8DLCC and DUTs up to 2m and 500 kg including full-body phantoms in a turntable, the F Series also expands the frequency range down to cover 200 MHz up to 40 GHz frequency ranges and the test modes to include EMC, BS, small cell, eNodeB and Virtual Drive Testing over the air (VDT-OTA). In an again unheard-of feature, the F-Series is also reverse-convertible into an Anechoic chamber, allowing Far Field (FF) and Spherical Near Field (SNF) radiation patterns, efficiency and gain measurements and pre-5G testing of antennas and devices. Conversion from RC to AC or vice versa can be performed within half a day.

Broadband Antenna
Vivaldi
The dbDIRECT Broadband Antenna features a broad frequency range of operation, high gain, small form factor and directional radiation pattern, making it highly attractive for widespread use in test and measurement of emerging wireless technology devices and radars. Contrary to conventional Vivaldi antennas limited to operating only at higher frequencies, the dbDIRECT Broadband Antenna design is optimized to operate at a frequency as low as 700 MHz up to 6 GHz. This lightweight and compact antenna design provides excellent matching over a broad frequency range.The antenna is designed to be placed in a DVTEST's portable anechoic chamber such as the dbSAFE enclosures for OTA (Over the Air) testing of DUTs. The antennas can be mounted in fixed positions to facilitate repeatable results. When used in conjunction with a rotary positioning mechanism, customers are able to detect the highest point of power sensitivity for enhanced accuracy and repeatability in measurements. In this configuration, both the antennas and DUTs can be positioned in order to facilitate the measurement.
