2. 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 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 Acqiris 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 han
3. The AS bus distributes both the clock and trigger signals along a plug in front panel bus between all the digitizers that participate in the system It allows any digitizer to act as the trigger source and any other digitizer to act as the clock source acquisition master enabling all the digitizers to be clocked at the same time Synchronizing the clock signals between the devices improves the accuracy of cross channel measurements and is essential for accurate time correlation between signals on different channels The AS bus is intended to connect modules of the same type i e of the same model number although some exceptions to this rule might be possible If modules with the same model number but different memory length options are connected only the shortest memory length can be used The AS bus connector is located on the front panel of each module Bridges are used to connect adjacent modules for synchronization which is then activated through software by defining a master module and the trigger source Up to 7 modules may be synchronized with the AS bus More detailed information and the commands required to set up the AS bus clock and trigger distribution are included in the Programmer s Guide and Reference manual User Manual Agilent Acqiris 12 bit Digitizers Page 25 of 48 3 8 Special Front Panel Inputs and Controls MMCX CLK IN 50 Q External Reference or External Clock Input MMCX I O A User configurable see below MMCX

Who needs a Geographical Map of Modules The GeoMapper application gives the user the possibility of telling the Acqiris driver crucial details of the physical position of modules when this information cannot be deduced directly It allows the driver to correctly adjust trigger and clock delays between the different modules of an AS bus multi Instrument and arrange the modules in an intuitive order The GeoMapper application has been implemented as a Wizard with the goal of learning the physical position of each module of a multi bus system The driver already knows the logical Bus and logical Slot numbers of each Acqiris unit present However because of varying conventions for the compactPCI slot arrangement on a bus this is not sufficient to determine the physical position Furthermore with the aid of the map the software can ensure that the modules of an Auto defined multi Instrument will be ordered to correspond to increasing physical slot number NOTE The unusual slot numbering convention of the CC121 is documented in the CC121 CompactPCI Crate User Manual The CC10X crates have a simpler slot numbering convention that the Acqiris driver already takes into account CompactPCI Crates from other manufacturers represent an unknown element NOTE The GeoMapper is of use for some AS bus systems in CC121 crates and perhaps crates from other manufacturers CC121 crate configurations with both an Acqiris acquisition module in one of the last 7 slots a
