Voltage Amplifiers: 1 GHz Ultra-Wideband

DUPVA-1 Series

Voltage amplifiers with variable Gain - 1 kHz to 1 GHz

The Ultra-Wideband Voltage Amplifiers Series DUPVA-1 is designed for fast and precision measurements with large dynamic range. Gain can be adjusted by the local gain selector or via an opto-isolated remote control interface. The gain independent frequency response guarantees for precise time resolved measurements at any gain setting. No significant change in rise time will occur when changing the gain setting which is essential for reliable time resolved measurements. Additionally, the frequency response is optimized for being very flat over the full frequency range. No gain peaking or significant distortion will occur in pulse and transient measurements.

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

Low Noise Input/Output Cable: CAB-LN1 Low Noise Cable
The LUCI-10 amplifier interface allows remote control of FEMTO amplifiers and photoreceivers with a remote control capability from a standard Windows PC with USB port.
