Product catalog summary
Introduction to Digital Detector Emulators
The document introduces Digital Detector Emulators, which are multichannel instruments designed to emulate radiation detection systems. These devices use the Monte Carlo simulation method to generate a continuous stream of pulses based on user-programmable statistical distributions such as energy spectra, time distribution, and noise. They can emulate signal pile-up and allow for the re-initialization or reproduction of sequences to study acquisition changes.
Specifications and Features
Each channel of the emulator can be independently programmed with its own statistics, and channels can be correlated in various ways. The emulators can generate different pulse shapes on the same channel, add noise and interference, and are controlled by dedicated software with a graphical user interface. They are suitable for testing and developing data acquisition solutions.
Applications
The emulators can be used for remote experimentation by importing waveforms and energy spectra from real detectors. They can also be coupled with a Time To Digital Converter for precise time resolution testing and simulate different pulse shapes for particle discrimination.
Product Models
  • DT5810B - Fast Digital Detector Emulator: Features dual channels, 1 ns rise time, and supports various operating modes including pulser, emulator, and waveform generator. It allows for correlated signal generation and includes an analog input for recording signals from real detectors.
  • DT4800 - Micro Digital Detector Emulator: A compact and cost-effective model suitable for single detector emulation and educational purposes. It features pulser and emulator modes, real energy spectrum emulation, and a user-friendly control software.
  • DT5800/NDT6800 - Digital Detector Emulators: Dual channel emulators that can operate in pulser, emulation, and waveform generator modes. They offer high accuracy emulation of radiation detection systems and are suitable for timing applications.
Additional Components
  • DT4700 - Clock Generator and FAN-OUT: A desktop module for synchronizing CAEN digitizers, featuring 10 differential LVDS outputs and the ability to work as a fan-out from an external source.
  • SP5601/SP5605 - LED Drivers: Fast LED drivers ideal for SiPM tests and characterization.
Comparison Table
The document includes a comparison table of the different emulator models, highlighting features such as channels, energy resolution, output range, noise emulation, and connectivity options.
Overview of LED Drivers
The document provides technical specifications and features of two LED drivers, SP5601 and SP5605, designed for sensor applications and photodetector tests respectively.
SP5601 Specifications
This LED driver offers tunable intensity and repetition rate, with triggering options via an internal pulse generator or an external source. The optical signal is delivered to the sensor through an FC interfaced fiber. Key features include a pulse width of 8 ns, violet LED color at 400 nm with 1500 mcd, and an output frequency range from 500 Hz to 5 MHz. The dimensions are 79 x 42 x 102 mm3.
SP5605 Specifications
The SP5605 is a fast UV LED driver, providing a triggered light burst ranging from a few photons to about 27,000 photons. It also features tunable intensity and repetition rate, with triggering options similar to the SP5601. The device ensures a constant wavelength signal from 100 Hz to 1.5 kHz. The pulse width is 4 ns, with a UV LED color at 245 nm. The dimensions are 80 x 42 x 80 mm3.
Common Features
Both models include optical output connectors (FC) and optical fibers. They are available in a desktop form factor.
Ordering Options
The SP5601 is available under the code WSP5601XAAAA as a LED driver for SIPM development kits, while the SP5605 is available under the code WSP5605XAAAA as a UV LED driver.

Signal Generators Applications Remote Experimentation discrimination where neutron sources are difficult to handle. Through the use of CAEN digitizers and digital MCAs it is possible to acquire and store both waveforms and energy spectra from real radiation detectors. The resulting files can be imported in the Digital Detector Emulators and used as a source for the emulation process. The Digital Detector Emulators are able to simulate different pulse shapes on the same channel (DT4800 excluded) allowing for detailed studies of such applications. It is therefore possible to emulate the real setup...
