Two-channel data acquisition unit with switchable high-gain preamplifiers for weak detector signals in spectroscopy systems.

The DCS300PA is a two-channel data acquisition unit with built-in, multi-range high-gain preamplifiers, intended for weak signals from photodetectors. It is an upgrade of the DCS103 and includes all of its acquisition functions. Besides the current/voltage inputs it provides an auxiliary voltage input, a temperature channel and two analog outputs for controlling a PMT high-voltage supply and an optical chopper.

Key Features

  • Two analog input channels with switchable current or voltage input and built-in preamplification
  • Current gain 10³–10⁷ and voltage gain 10⁰–10⁴
  • 16-bit A/D conversion, integration time from 10 µs to 10 s
  • Two 12-bit analog outputs (0–10 V DC): one for PMT high-voltage control, one for chopper control
  • Auxiliary 0–10 V DC input and AD590 temperature channel (-30 to 100 °C)
  • Software or external TTL trigger; 5 digital inputs and 2 TTL outputs
  • USB 2.0 interface, CE marked

Typical Applications

  • Signal acquisition from PMTs, photodiodes and infrared detectors
  • Spectral scanning with monochromators
  • Weak-signal measurements in fluorescence and absorption spectroscopy
  • Control of PMT high-voltage supplies and optical choppers
