  • 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.

  • Wideband Active Filters

  • 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

  • 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.

  • Rubidium Oscillator

    IQRB-2 - IQD Frequency Products Ltd

    The IQRB-2 low noise rubidium oscillator is a sub-miniature atomic oscillator combined with 'active noise filter' technology. This rubidium oscillator has 100 times less drift than OCXOs and with short term stability of 0.002ppb/s at 100s this rubidium oscillator provides significant improvements in performance over other rubidium components.

  • Line-Scan Camera

    ELiiXA+ - Teledyne DALSA

    The ELiiXA+ family features Teledyne e2v’s recently developed multi-line CMOS technology, providing high line rates and combining high response with extremely low noise levels. This delivers high signal to noise ratio even when short integration times are required or when illumination is limited. Pixels are arranged in two active lines and dual line filter configuration allows the cameras to be operated in several modes.

  • Precision Low-Loss Multiplexers

    Maury Microwave Corporation

    Maury’s line of diplexers (DP-series) and triplexers (TP-series) are designed for applications which require combining/ splitting signals at or around harmonic frequencies (nFo) and are connectorized for design-in and test and measurement applications.DP-series diplexers are designed using low-pass and high-pass filters and pass bias between the low-frequency (or Fo) port and the common (or DUT) port.TP-series triplexers are designed using low-pass, bandpass and high-pass filters and pass bias between the low-frequency (or Fo) port and the common (or DUT) port.Power handling is rated at 100W CW (average) and typical insertion loss is better than 0.5dB between the low-pass (Fo) and common ports.DP- and TP-series multiplexers are ideal accessories for passive, active and hybrid-active multi-harmonic load pull systems.

  • Iifrasound Monitoring System

    INFRASONITUS - BioAge s.r.l.

    The infrasonic signal, acquired by a suitable microphone, is filtered by an active low-pass filter of the fifth order with a cut-off frequency at 20 Hz, with low noise, then it is sampled and acquired by a 16-bit ADC with a speed of 50 samples. / sec. The amplification factor can be set to 0.1 / 0.5 / 1/10.The infrasonic monitoring system includes a complete diagnostic functionality that performs an exhaustive functional test without the use of other tools: this function is extremely useful when the system is installed on the volcano at high altitudes.
