Overview
The CAEN Mod.DT5800 is a Dual Channel Detector Emulator, an instrument for emulating in real time signals from generic setups for radiation detection, which can be operated as Desktop units. It shares the same functionalities as the NDT6800 and can operate in three modes: Pulser Mode, Emulation Mode and Waveform Generator Mode.
The output generated by the device can go up to 2 V (4 V in case of high Z) and the maximum pulse rate is 10 Mcps (5 Mcps in Poisson statistics mode). In the detector emulator operating mode, the system is able to emulate with high accuracy a radiation detection system from the detector output to its related front-end electronics. The user can program different emulation parameters like signal shape distributions, energy spectra, time distribution, as well as noise characterization and baseline drift.
Thanks to the 12 ps/step delay generator they are particularly suited for timing application. Moreover, the multiple shapes capability can be used for pulse shape discrimination applications. The two channels can be correlated either with the same or different statistical distributions.
Operating modes:
- PULSER Classic pulser operation. The system allows to set the signal amplitude, the signal rate, and to choose between constant and Poisson distributed rate.
- DETECTOR EMULATOR In the detector emulator operating mode, the system is able to emulate with high accuracy a radiation detection system from the detector output to its related front-end electronics. The user must provide: the signal shape distribution, the required energy spectrum, the time distribution, the noise characterization, and the baseline drift.
- The signal shape can be generated either by using the system internal database, or using recorded shapes from the experimental setup. The same is true for the energy spectrum. It is possible to create several emission lines through the tool itself, or to import a file in the format of CVS/ANSI N42.42, or to use the internal database electronics. The user can choose a Poisson or any arbitrary time distributions. It is also possible to emulate white noise, 1/f noise, random walk, as well as interferences. The characterization of the baseline drift can be also added.
- CORRELATED EVENT GENERATOR The instrument allows to generate correlated events with fixed time shift (time steps of 12 ps). The two signals can have either the same or different statistical distributions. Furthermore, it is possible to generate a subset of events according to a fixed energy spectrum, being statistical uncorrelated from the background events.
- ARBITRARY WAVEFORM GENERATOR The instrument comes with 1M points of RAM memory per channel to store and then reproduce the events from pre-defined functions.
The Desktop Digital Detector Emulator is available in dual channel (DT5800D) version and allows the event correlation.
USB 2.0 communication interface. Software tool compliant with Windows OS. Shape and spectrum files import from any Digital Pulse Processors, Digitizers, and oscilloscopes. Model shape generation (with no noise) from input waveforms.
Programmable digital outputs: Trigger in, Trigger out, and Gate.

- Correlated events emulation
- Three operation modes:
1) Channel 1 (CH1) is the time shifted copy of Channel 2 (CH2) (12 ps step);
2) CH2 has its own statistics generator (i.e. different spectrum, different noise, etc.) but is triggered by CH1 (delayed by 12 ps step);
3) A third emulator channel (with separate statistic properties) generates correlated pulses for both CH1 and CH2. In this way, only some events of the two channels are correlated - 12 ps step programmable delay (from 0ps to 32us), 18 FWHM, 60 ppm linearity
