Energy emulation
features | - Single line (65535 selectable levels) - Spectrum emulation (16384 bins with 14 bit resolution) - ± 2 V, 50 Ω; ± 4 V, hi-Z(high speed mode) - ± 8 V, hi-Z (high voltage mode) - 16 bit D/A converter |
| Time emulation features | - Costant rate emulation - Poisson distribution - Programmable statistical generation of events (256 bins, 8 bit resolution) - Up to 30 MCPS, both in costant and statistical emulation - Integrator circuit emulation without pile-up limitation - Up to 16 pile-up events in the memory based algorithm - Programmable dead-time and emulation of parallelizable and non-parallelizable machines - 20 ns to 10 ms exponential decay time |
| Signal shape | - 4096 points to store waveforms - Arbitrarily programmable shapes - Shape length from 3 ns to 4 µs (w/o interpolation) / 4 ms (interp.) - Separated rising and falling edge interpolation - Up to four separate shapes mixed on the same channel with indipendent statistic |
| Noise emulation | - White noise emulation (BW 500 MHz) - 1/f noise emulation - Random Walk (baseline drift) - Interference generation (e.g. possibility to record spikes from switching power supplies and inject in the output signal) - Interference generation with fixed amplitude and frequency or randomly modulated in amplitude and injection time |
| Baseline | - Baseline drift programmable with arbitrary shape |
| Correlated events emulation | - Three operation modes:
1) Channel 1 (CH1) is the time shifted copy of Channel 2 (CH2) (1 ns step);
2) CH2 has its own statistics generator (i.e. different spectrum, different noise, etc.) but is triggered by CH1 (delayed by 1 ns 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 - 1 ns step programmable delay (from 0ps to 32us) |
| Digital I/O | - 2-input and 2-output programmable - Trigger out, analog saturation warning, machine overload sensing - Trigger in, random number generetor control (reset / play / pause), gating, baseline reset |
RNG
(random number generator) | - 8 indipendent LFSRs with 64 bits generate the base for the statistical emulation - Possibility to randomize the seeds of each RNG indipendently - Possibility to inizialize the RNG with fixed seeds to get repetible sequences to test different processing architectures - Generation of finite length streams of pulses to debug step-by-step the DUT |
| Programmable sequence | - 4 kpoints of memory/CH to store a sequence of pairs (energy, time of occurrence) to generate long predictable and defined sequences of pulses. |
| Arbitrary waveform generator | - Function generation: sin, square, ramp, saw, pulse, sinc up to 100 MHz |
| Software and Interfaces | - Windows based user interface managing more than one emulator - USB 2.0 interface |
| Analog Input | - 1 ADC input, 125 MSPS 14 bit - DC coupled input (dynamic 1/2/4/8 V) - AC coupled (gain from 2 to 110) - Realtime emulation signal mixing with analog source - Full MCA functionality to calculate the spectrum of the source - Fast shape averaging to extract a model of the input signal |
