About This Product

■Product overview

The SR570 Low Noise Precurrent Amplifier is a high performance, low noise current preamplifier. The main unit has a built-in battery and can be operated without power supply from the line. Input offset adjustment and variable bias voltage setting are possible. Equipped with 0.03 Hz to 1 MHz low-pass and high-pass filters, it can also be used in combination as a band-pass filter. Additionally, toggling and blanking are possible by inputting an external TTL signal.

■Features

・5 fA/√Hz input noise ・Frequency band 1MHz (maximum) ・Gain 1pA/V (maximum) ・Variable bias voltage ・Variable input offset ・Low noise, high BW, low drift mode ・With high pass/low pass/band pass filter ・Battery powered ・With RS232 interface

■Applications

・Voltage conversion of small current signals ・Low temperature measurement ・Photomultiple, photodiode signal amplification
