User Manual Family of 12 bit Digitizers Page 39 of 66 acqiris rearm time A fast trigger rearm helps produce very low dead time between the segments of a sequence acquisition The dead time is the period after the end of an event when the card cannot digitize data for a new trigger event To complement this mode of operation the digitizer can also measure and store the arrival time of each trigger using the information from the on board TTI Trigger Time Interpolator Readout of the individual trigger time stamps makes it possible to determine the time from one trigger to any other trigger in the sequential acquisition The TTI resolution sets the resolution of the trigger time stamps see section 3 3 4 Timing 3 3 4 Timing A crystal controlled timebase is used to clock the ADC system of the digitizers The timebase accuracy is guaranteed to be better than 2 ppm The digitizers also include a built in Trigger Time Interpolator TTI that measures the time from the trigger point to the first sample point This information is essential for determining the relation between the trigger or other event of interest and the digitized samples of the signal The TTI resolution is 5 ps for a sampling interval of 2 5 ns SR 400 MS s As the SR decreases the TTI resolution is kept at 0 2 of the sampling interval However there is a jitter of up to 60 ps in the positioning of the data with respect to the trigger point 3 3 5 Timebase

27. Range The timebase range defines the time period over which data is being acquired For example the DC440 has a standard acquisition memory of 64 Kpoints and maximum warranted sampling rate of 400 MS s Therefore at this sampling rate the digitizer can record a signal over a timebase range of up to 160 us approx 64 000 points 2 5 ns point The timebase range can be adjusted by varying the amount of acquisition memory or the sampling rate of the digitizer 3 3 6 Sparkle code rate The high end Acqgiris 12 bit digitizers DC440 and DP310 contain an analog to digital conversion ADC system that can sample waveforms at rates up to 420 MS s This makes them ideally suited to frequency domain observations On the other hand real time single shot waveforms are used in other applications and one of their important specifications is the sparkle code rate This is the probability that a sampled data point differs from its true value by more than a specified deviation For the purposes of this discussion we take the allowed deviation to be 3 1 FS 128 ADC counts At lower sampling rates lt 200 MS s all of the 12 bit digitizers show a low occurrence of sparkle codes The sparkle code rate is 10 typical at 200 MS s However at sampling rates above 200 MS s the chances of a sparkle code occurring increase with the sampling rate The sparkle code rate reaches 10 typical at 400 MS s 3 4 Trigger The trigger settings applied to the digitizer
