  • AC and DC Electronic load

    63800 series - Chroma ATE Inc.

    The Chroma 63800 Loads can simulate load conditions under high crest factor and varying power factors with real time compensation even when the voltage waveform is distorted. This special feature provides real world simulation capability and prevents overstressing thereby giving reliable and unbiased test results. The 63800's state of the art design uses DSP technology to simulate non-linear rectified loads with its unique RLC operation mode. This mode improves stability by detecting the impedance of the UUT and dynamically adjusting the load's control bandwidth to ensure system stability. Comprehensive measurements allow users to monitor the output performance of the UUT. Additionally, voltage & current signals can be routed to an oscilloscope through analog outputs. The instrument's GPIB/RS232 interface options provide remote control & monitor for system integration. Built-in digital outputs may also be used to control external relays for short circuit (crowbar) testing.

  • Broadband Antenna

    Vivaldi - DVTest Inc.

    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.
