Digital Detector Emulator

THE MOST ADVANCED SYSTEM IN THE WORLD 
FOR REALTIME EMULATION OF RANDOM SIGNAL
FROM RADIATION DETECTOR

NOT A PULSE GENERATOR OF RECORDED SHAPES

BUT A SYNTHESIZER OF TRUE RANDOM PULSES

COMPLIANT TO PROGRAMMABLE STATISTICS

FOR AMPLITUDE, STARTING TIME AND SHAPE 

Real-time emulation of the most important phisical effects: energy spectrum distribution,
poisson time distribution, pile-up, multiple different signal shape on the same channel, variable rise/fall time from 1ns to ms, noise (gaussian, random walk, flicker, shot), baseline drift.
Emulation of RC and transistor reset pre-amplifier.

DT5810 comes with Analog Input for automatic detection system characterization (spectrum measurament, signal shape).

The output of the MCA could be used to initialize the emulation process.

WHAT IS THE DETECTOR EMULATOR

pic01 (1)

The Digital Detector Emulator is an instruments for emulating in real time signals from generic setups for radiation detection.

The instrument is not a pulse generator of recorded shapes but a synthesizer of true casual pulses compliant to programmable statistics for amplitude, starting time and shape. The emulated signal reflects the characteristics of the programmed features (e.g. energy spectrum, time distribution, noise spectrum and intensity, shape distribution) and the stream of signals is a statistic sequence. In fact when the emulation process is reset, the kernels of generators are re-initialized with new random data (from a physical source) making the analog output sequences always different.

The instrument is able to emulate two different radiation sources at time and provide it on two independent outputs. The two emulation chains are fully independent in all configuration parameters: energy spectra, signal shapes, temporal distributions of the events, noise characteristics, etc. Moreover it is possible to link some parameters or set the instruments in a master/slave (for correlation events emulation) mode where the first channel works as a trigger of the second one.

The instrument is able to generate analog delayed signals with a resolution of 12ps from 0 to 20us.

THE NEW DT5810 FEATURES

• Sub ns rise time:  emulate even faster diamond detectors
• High rate emulation:  statistic distribution (energy/time) up to 20 Mcps
• Multi-shape:  up to 4 different shape on the same channel with statistical distribution
• Zero dead time:  1ns minimum distance between events
• Ultra low noise:  less then 200 uVrms (low noise config.)
• Dual output analog path:  ±9V high voltage for PMT emulation and ±2V high speed output for fast detector emulation
• Waveform generator:  25 MHz waveform generator and 32 Mword AWG
• Instrument synchronization:  Share clock between multiple devices to synchronize generated pulses.
• New amazing control software:  Control multiple emulators, real-time monitor of output and input channels.
• Coincidence:  Two outputs could work in correlation mode generating signal in coincidence with 1ns step programmable delay.
• Display:  Monitor the emulator status from the two high resolution OLED display

DT5810 ANALOG INPUT

• Analog Input:  125 MSPS, 14 bit digitizer

• Automatic Detection System characterization:  Connect the DT5810 input to the output of the pre-amplifier/shaper. The integrated MCA will calculate the spectrum and estimate the signal shape. The result could be use to initialize the emulation process. Obviously the user could configure the emulator to replicate the input signal also changing some parameters like: rate, noise, signal shape or edit spectrum add extra peeks

• Realtime signal mixer:  User could replicate on one or both outputs the input signal mixing it to emulated signals. For example it is possible to mix the real gamma-ray only signal generated by a real detector with an emulated neutron source.
