-
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)
