  • Preamplifiers

    Com-Power Corporation

    Com-Power broadband high gain preamplifiers were designed for electromagnetic interference (EMI) testing and certification. EMC test labs use preamplifiers to improve sensitivity of the test system during EMI radiated emissions measurements. Without a high gain preamplifier, signals picked by the antenna that have amplitudes below the noise floor of the test system cannot be measured. The preamplifier gain has minimum variations for the entire operating frequency range for accurate emissions measurements. The Com-Power preamplifiers were primarily intended for EMC applications. However, it can be used for other applications that require signal amplification.

  • High Voltage Op Amplifiers ≥12V

    Analog Devices Inc.

    High supply voltage op amps are used in systems that demand the widest dynamic range with the best signal-to-noise ratio.

  • Precision Impedance Analyzer (20Hz to 10MHz)

    ST2839 - Saluki Technology Inc.

    ST2839 series precision impedance analyzer is a new generation impedance test instrument by adopting the current international advanced automatic balance bridge principle. Its basic accuracy of 0.05%, the fastest test speed of 5.6ms, the frequency range of 20Hz-10MHz, and the impedance test range of up to 1GΩ can meet the testing requirements of components and materials, especially for low-loss (D) capacitors and high-quality Measurement of Factor (Q) Inductors. The four-terminal pair port configuration method can effectively eliminate the influence of the electromagnetic coupling of the test line, and expand the lower limit of the low-impedance test capability ten times lower than that of the conventional five-terminal configuration instrument.

  • Test Fixture, Shielding Effectiveness

    EM-2108 | 1.5 GHz – 10 GHz - Electro-Metrics Corp.

    The EM-2108 is a standard test fixture for evaluation of the electromagnetic shielding effectiveness (SE) of planar materials. The fixture is a section of coaxial transmission line broken to allow the insertion of planar test materials. Although ASTM D4935-10 is currently limited to an upper frequency of 1.5 GHz, the EM-2108 meets and complies fully with both the impedance and SE requirements called out in ASTM test method D4935-10 up to 10 GHz. These results are shown in Figures 1 & 2. The measured data relates to the shielding effectiveness due to a plane wave (far field EM wave) from which near field values for magnetic and electric fields may be inferred.
