Data Patterns' core business for over 20 years has been the development of Automated Test Equipment for critical aerospace requirements. Data Patterns developed a Multi Programmer with associated test automation software in 1994. Christened the DP-800 this product was adopted for the implementation of test rigs for Navigation Platform Test Benches, Engine Test Bed Automation, Cable Harness Test Systems, etc. This product was effectively utilized in the development of test benches required by Indian Space Research Organisation (ISRO) for the Polar Satellite Launch Vechicle (PSLV) and Geo Stationary Launch Vehicle (GSLV). Based on this foundation, the next generation test benches were developed in the cPCI architecture. Presently, Data Patterns develops cPCI based test systems for Laboratory applications as well as VME based test systems for challenging environmental conditions. Examples of test solutions built by Data Patterns are indicated below.

Dual Polarized Antennas
-
Dual polarized horn antennas are offered as both standard and custom models with rectangular waveguide interfaces for both horizontal and vertical ports. These dual polarized horn antennas support both linear and elliptical polarized waveforms. When the antenna receives a circular polarized waveform, equal amplitude linear polarized waveforms are output at both horizontal and vertical ports. When two equal amplitude linear polarized waveforms are input into the vertical and horizontal ports, the antenna will transmit a circular polarized waveform. The listed models offer 15 dB nominal gain and 33/28 degrees typical half power beamwidth at the center frequency of the band. They also exhibit 40 dB typical port isolation and 35 dB nominal cross polarization. These antennas cover full waveguide bandwidths within the frequency range of 8.2 to 110 GHz. In addition to the models listed below, models with 10, 20, 23 and 25 dB gain and other frequency bands are also available.

Planar-Doped Barrier Diode Detector, 0.01 to 50 GHz
8474E
-
The Keysight 8474E is a high-performance detector using a gallium arsenide, planar-doped barrier detecting element. It features extremely flat frequency response over its entire band of operation and very good frequency response stability versus temperature. The Keysight 8474E is also very rugged with high resistance to ESD damage. The Keysight 8474E detector is available with a 2.4-mm (0.01 to 50 GHz) connector. This detector offers the options for optimal square-law loads (Option 102) and for positive polarity output (Option 103). Because the unit-to-unit frequency response tracking of this device is typically better than plus or minus 0.3 dB, no matched response option is offered.
