  • Three Phase AC Voltage Source

    EAC-TAVS - Electronic Test & Power Systems

    The EAC-TAVS is a series of programmable high power AC voltage sources. Each system provides a three phase true sinewave output as standard. Each unit is built in a freestanding cabinet. The output frequency is adjustable in the range of 45 - 105Hz. Different frequency ranges are optional, with up to 805Hz possible. An RS-232 and CAN interface are provided as standard. The high resolution TFT front panel displays a host of measurement and setting functions. Besides standard models, other nominal power levels and voltages can be user specified. Single phase and bidirectional versions are available on request.

  • Environmental Testing Services

    INO

    INO offers a range of environmental testing services to help you perform prototype qualification and durability testing in the fieldtwo critical steps in the development of a reliable and profitable product. Our services can be used in a variety of settings, including quality control, land, sea, and air transportation simulations, accelerated aging simulations, resonance frequency searches, specifications and standards compliance testing and product qualification testing for standards such as MIL-STD, FOTP, and ESA.

  • Gas Leak Detector

    GSD600 - Amprobe Test Tools

    The Amprobe GSD600 Gas Leak Detector is a fast responding gas leak detector for methane and propane gas. The meter emits a frequency tone when gas is detected. The frequency of the beep coincides with the concentration of the gas. The LEDs display the level of gas present in an area or room. Pinpoint gas leaks for closed piping systems. Use the mute function in quiet work areas and utilize the LED displays. Or a standard earphone jack for hearing the meter in loud environments.

  • VME 32X 5 Slot 6U

    Comtel Electronics

    ANSI/VITAV 1-1994 VME32 Backplane, 6U 5 Slot Including J1 & J2.Benefits:• Standard VME backplanes are available also in other slot count configurations• Surface Mount Technology – Excellent high frequency performance, high reliability and reduced cost due to SMT

  • High Voltage Passive Probes

    Teledyne LeCroy

    The PPE6KV-A and HVP120 can handle up to 6000 Vpeak transient overvoltages and are designed for probing up to 2000 Vrms and 1000 Vrms respectively. Fast rise times, excellent frequency response, and a variety of standard accessories make these probes safe and ideal for high voltage measurement applications

  • Full Band Noise Figure and Gain Test Extenders

    STG-06-S1 - ERAVANT

    Full band noise figure and gain test extenders are offered to extend noise and gain measuring capabilities up to higher millimeterwave frequency ranges. These extenders are designed to interface with noise and gain test systems that have an input IF of 10 MHz to 1.6 GHz, such as the industry standard Keysight 8970A/B, N8975A and Maury MT 2075B. The noise figure and gain test extenders include a high-performance, solid-state noise source (STZ series) and a full waveguide down converter (STC series), which consists of a Faraday isolator (STF series), full band mixer (SFB series), frequency multiplier, and IF amplifier. A frequency source with an output signal in the frequency range of 10 to 20 GHz is required as a local oscillator for the down converter. The noise source is automatically powered on and off by the noise figure meter.

  • Components - Passive Multipliers (FT)

    FT Series - Farran Technology Ltd

    Farran Technology manufactures a series of standard frequency multipliers which are available in fixed or tunable versions. GaAs Schottky barrier varactors are used to achieve the highest efficiency.  The multipliers can be used with solid state or vacuum tube sources. A rugged compact mechanical design is used to maximise reliability.

  • DC to DC Converters and Thick Film Hybrids

    Frequency Electronics, Inc.

    Since 1963 we have built thousands of converters, many as part of our own highly regarded frequency control products. (Ninety-four satellite and space exploration programs have used FEI precision time-frequency standards.) We now offer proven DC-DC converters separately.

  • EMC- EMI test Equipments

    EMCTEST

    Our AFJ FFT 3100 & 3300 EMI Receivers cover the full frequency range from 9kHz to 3GHz.To allow a greater flexibility GTemCell can provide either a single or multiple solution of receivers to cover the most common standards and regulations such as CISPR, EN, IEC, FCC etc.

  • Impulse Spark Tester

    IT-25B - Clinton Instrument Company

    While most military standards now favor high frequency spark testing over impulse spark testing, the IT-25B Impulse Spark Tester is available for use in some aeronautic applications that still specify the impulse method. The IT-25B meets the test requirements of military specifications MIL-C-13777E, MIL-W-16878, and NEMA standards for hook-up wire used in high temperature wire applications. This method is favored as an alternate to a wet dielectric test.
