  • Active Filter

    J2190A - PICOTEST Corp.

    The J2190A active filter presents a high impedance (approximately 150kOhms) minimizing the loading of the circuit being tested. The output impedance is 50 Ohms allowing low noise coaxial connections to all typical test equipment. The 0.1Hz-10Hz noise band is common for opamp measurements, voltage regulators and voltage references. Many application notes offer schematics of such a filter for test purposes. An engineer’s time is much too valuable to be spent building test equipment. We have created a 4th order high pass and 4th order low pass filter with an optimally flat response and 0dB gain. Additional filters can be cascaded for even sharper cutoff.

  • Parallel Active Multifunction Filter

    SINAF 3.0 - Lifasa - International Capacitors, SA

    The active filters offer the best possible solution to solve the problems related to the quality in the electrical network, both in industrial three-phase installations, as commercial or service installations. These problems are caused, not only by the harmonics, but also by the consumption of reactive power (generally of capacitive type).

  • Time-domain Field-Device-Circuit coupled simulator

    EM-SUPREME® - PedaSoft LLC

    Time-domain Field-Device-Circuit coupled simulator for modeling of passive structures, active components, and complete RF & millimeter-wave modules.

  • Return Path Noise Power Ratio Test Set

    NPRT 2200 - Applied Instruments, Inc.

    The NPRT 2200 performs Noise Power Ratio measurements to determine the dynamic range of optical transmitters, amplifiers and other active devices used in HFC networks. It has an internal broadband noise source, selectable filters and a measuring receiver.

  • CAT-5 Video Variable Filters

    Analog Devices Inc.

    It is often beneficial to use a video driver at the output of a video encoder for power savings, line driving, and additional circuit protection. The video driver is typically configured as an active filter, also known as a reconstruction or anti-imaging filter. The purpose of the reconstruction filter is twofold: it blocks the higher frequency components (above the Nyquist frequency) that were introduced into the video signal as part of the digitization process and provides gain to drive the external 75 Ω cable to the video display.

  • Band Reject (Notch) Filter Components

    Frequency Devices Inc.

    precision band-pass and band reject (notch) active filters that provide high performance in a compact 32-pin DIP package, with a broad range of fixed center frequencies (fo) from 1 Hz to 100 kHz. Each filter type features a neartheoretical amplitude/phase response along with lowoutput voltage noise enabling these filters to achievea 10,000:1 or better dynamic signal range.

  • EMC/EMI

    Schaffner

    Harmonic filters help to obtain compliance withinternational standards like e.g. IEEE 519-1992 or EN 61000-3-12, and with local utility codes. They reduce electrical andthermal stress upon the electrical infrastructure, eliminate the risk of harmonics-related reliability problems, and supportlong-term energy efficiency and cost savings. Ecosine passive filters are the industry standard for 6-pulse rectifiers andnon-regenerative motor drives to achieve the often specified level of < 5% THID. Ecosine active harmonic filters providelatest generation digital technology. With a response time of less than 300 µs an efficient harmonics mitigation, powerfactor correction, and load balancing is achieved in real time.

  • ELiiXA+ 16k Mono And Colour

    Teledyne e2v

    Teledyne e2v’s next generation of line scan cameras are setting new, high standards for line rate and image quality. The ELiiXA+ 16k features Teledyne e2v’s recently developed multi-line CMOS technology, providing an unmatched 200,000 lines/s and combining high response with extremely low noise levels. This delivers a high signal to noise ratio even when short integration times are required or when illumination is limited. The 5μm pixel size is arranged in four active lines in the monochrome model and two active lines in the colour model. The dual line filter configuration allows the camera to be operated in several modes.

  • ELiiXA+ 8k Mono And Colour
