Millimeter Wave Antenna Testing
-
If you are involved in antenna or system level design using mmWave or THz frequencies, then you understand the importance of dependable testing equipment. It may be that you are designing passive phase array or that you are designing a mmWave radar sensor system, but when it comes to validation of your design, simulation can only bring you so far. Phased array antennas have to be measured over the air (OTA) to ensure the radiation pattern of your design efficiently conducts energy in the right direction which is where the MilliBox comes in.

Over The Air (OTA) Tests
-
OTA testing is a way to ensure that the wireless devices designed or selected are performing as expected. The OTA test measures the entire signal path and antenna performance. The antenna performance is influenced by different product requirements, applications, size of the housing, materials, bandwidths, frequencies, etc.

Super MUTT Deluxe Standard Edition
#9008-SE
-
Innovative Products of America
The Super MUTT places a load on the trailer's electrical circuits to identify wiring problems while providing remote control operation over both air brakes and lights. Built to facilitate a one-man testing operation, the Super MUTT reduces guesswork and inspection time to prevent failures that lead to expensive road calls and citations. The remote control allows for repetitive air brake actuation at each axle to reveal developing problems often missed by normal testing procedures.

Optimize Throughput And Cost For MmWave 5G Device Functional Test
Functional Test
Test engineers always have faced tough new test-coverage challenges. Those introduced by 5G measurements at mmWave are no exception, as they require over-the-air (OTA) radiated test solutions. But never have these pressures seen today’s intense time-to-market, manufacturing volume, and operational expectations! A solution that meets these demands must:

Medium-size Reverberation Chamber
E-Series
-
The E medium-size multicavity Reverberation Chamber Series represents that state-of-the-art in reverberation chamber technology. The E-Series can make single measurements, batch tests, protocols or campaign tests for different frequency bands, different technologies and different channel models, running overnight without human intervention. Embedded frequency-, mode-, source- and platform-stirring in a double-shielded set of cavities allow Passive MIMO (Efficiency, Correlation, Diversity Gain, MIMO Capacity and others), Active MIMO OTA (TRP, TIS, TPUT, MTS, CQI, M2TxDT, RSRP, MCL and others) and Time-Domain MIMO (DL/UL TCP/UDP TPUT, RMS DS, STD, PL, CBW, Mute%, eNodeB, VDT-OTA) measurements up to 8x8 and 8DLCC to be performed for antennas and devices up to 50cm and 50kg ranging from 2G to 4G, covering all available cellular and wireless technologies to date, including wearables devices, sound acoustic mute, WLAN and W-IoT testing. There is no RC in the market more advanced than the E-Series.

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.

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.
