Overview

The N568E is a 16 channel spectroscopy amplifier implemented in a single-width NIM module. The following versions are available:

Version N568ELC N568E N568EB
Description 16 Ch Low Cost Ethernet Prog. Spectroscopy Amplifier 16 Ch Ethernet Prog. Spectroscopy Amplifier 16 Ch Ethernet Prog. Spectroscopy Amplifier
Shaping time 0.2, 1, 3, 6 µs 0.2, 1, 3, 6 µs 0.1, 0.2, 1, 3 µs
Impedance 50 Ω 50 Ω 50 Ω
Features Low cost Low noise Low noise

For each channel the amplification gain, the output polarity, the shaping time and the pole-zero cancellation, are remotely programmable, either via USB or Ethernet; the RS485 port al lows to connect up to 32 daisy chained modules. The gain ranges from 0.15 to 480.

The working parameter values are automatically stored in a non-volatile memory. A semi-Gaussian output is provided either with the programmed gain (OUT) or with a further 10x amplification (XOUT), either direct or inverted. A Common Offset can be programmed via software and allows to shift the baseline of the output. A FOUT output provides a fast amplification for timing purposes (fixed gain factor of 20). A MUX OUT allows to monitor both the OUT and the FOUT outputs of a single channel.

The N568E is supported by freely downloadable CAEN-CSA software, available for both Windows and Linux OS.
