  • Ultra Low Noise Preamp

    J2180A - PICOTEST Corp.

    The J2180A low noise preamplifier provides a fixed, AC coupled 20dB gain while converting a 1 MOhm input impedance to a 50 Ohm output impedance. With a 3dB bandwidth of 0.1Hz to 100MHz, the preamplifier improves the sensitivity of oscilloscopes, network analyzers and spectrum analyzers while reducing the effective noise floor and spurious response. The preamplifier can also serve as a low frequency DC blocker for a spectrum analyzer or you can use it to connect a high input impedance oscilloscope probe to 50 Ohm equipment.

  • Low Noise Prepolarized Microphone

    378A04 - PCB Piezotronics, Inc.

    The 378A04 is a matched system that is comprised of a high sensitivity microphone and a low noise preamplifier that contains a built-in filter that enables the free-field response to remain flat over a wide frequency range. The system requires a minimum of 4 mA and measures to 6.5 dBA (5.5 dBA typical) within a cost efficient, prepolarized (0V) design. PCB's model 378A04, the industry's first prepolarized low noise microphone and preamplifier system allows you to measure extremely low amplitudes. In the past this was only possible with externally polarized solutions. With a typical noise floor of 5.5dBA, this microphone system delivers all of the benefits commonly associated with prepolarized systems.
