  • »GHz Variable Gain Voltage Amplifiers

    • Variable gain up to 70 dB (approx. × 3000), switchable in 10 dB steps
    • Bandwidth 1 kHz to 1.2 GHz
    • Bandwidth independent of gain setting (guaranteed)
    • Noise figure down to 1.9 dB (330 pV/√Hz)
    • Local and remote gain control

    APPLICATIONS

    • Oscilloscope and transient recorder preamplifier
    • Photomultiplier and microchannel plate amplifier
    • Signal booster for optical receivers and current amplifiers
    • Time-resolved pulse and transient measurements
    • Automated measurement systems

    Indication of selected gain setting by LED. Output short-circuit protected. Power supply via 3-pin Lemo® socket. A mating connector is provided with the device. Optional power supply PS-15 available. For further information please view the datasheet.
