  • Programmable/Direct Reading Attenuators

    ERAVANT

    Is a dual function direct reading and programmable rotary vane type attenuator for use in millimeterwave systems across the standard WR-03 frequency range of 220 to 330 GHz. The attenuator is an ideal piece of equipment in waveguide systems where a broad direct reading of attenuation is required. The default mode of operation is manual direct reading. In manual mode, the attenuation is adjustable with the large knob and the digital LCD screen displays the current attenuation value. The LCD screen is powered by an internal rechargable battery, which is charged via the 2.5mm DC jack by a provided DC to AC adapter. The 2.5mm DC jack also provides power to the stepper motor, encoder and internal microprocessor for the programmable mode function. The user can quickly switch to programmable mode by connecting the powered-up attenuator to a computer with the USB Type B port. In programmable mode, the attenuation is finely adjusted with a precision stepper motor by the internal microprocessor via user-entered serial port commands from the computer.

  • Low-Density PXI Switch Matrix Modules

    Pickering Interfaces Ltd.

    Our low-density PXI switch matrix modules are a cost-effective solution for applications that require relatively small matrices in the PXI format. These low-density switch matrices can be expanded by connecting together multiple modules, however, we recommend that users look at the higher density switch matrix modules that involve less user configuration. Reed relay versions use high quality sputtered ruthenium relays that exhibit excellent contact performance under low and medium level switching conditions. For general purpose applications that also require higher power handling, the range of electro-mechanical relays provides an ideal solution.

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.

  • PXI 1A Fault Insertion Switch 22-Channel

    40-195-001 - Pickering Interfaces Ltd.

    The 40-195 is a 22 Channel Fault Insertion Switch, primarily designed for the simulation of fault conditions in automotive & avionics applications involving the reliability testing of safety critical controllers. It is designed to be able to insert different fault conditions on pairs of signals between the test fixture and the equipment under test: Open-Circuit, Short-Circuit between signal pairs, Short-Circuit between signal pairs and user applied fault conditions e.g. Power or GND. Relays in-line with the signal paths allow open circuit conditions to be simulated on either side or both sides of a signal pair. Relays between each channel pair enable adjacent signals to be shorted, and relays between signal paths and the "Fault" connection allow the application of external user applied fault conditions.
