2. The readout process may be restricted to pre defined sections of the acquired waveforms defined by gates Alternatively in the AP101 and AP201 the data of interest may be processed to give peak information before readout 3 7 Data processing Processing is done under control of the host computer after the acquisition is complete and before the readout is started In the simplest case this processing does nothing to the data and terminates immediately If real processing is needed the throughput is 130 MS s ignoring start up effects associated with each gate The actual amount of data to be processed can be reduced significantly by intelligent use of the gate definition and of the processing parameters for the peak detection The scans for positive and negative peaks are done in parallel 3 7 1 User Gates Gates can be used to define regions of interest within an acquisition segment This can be used to limit the amount of data to be transferred or as a starting point for peak detection processing A gate is defined as a range of data defined by a first sample and the number of samples in the gate Both the first sample and the number of samples must be multiples of 4 An arbitrary number of gates up to 4095 for AP235 AP240 or 64 for AP101 AP201 can be defined They are used for each segment in the acquisition User Manual Family of Analyzers Page 45 of 65 acqiris 3 7 2 Threshold gates AP240 SSR only The data itself can also

4. Time Base Range The Time Base Range defines the time period over which data is being acquired For example the AP240 can have an acquisition memory of 16 Mpoints and maximum sampling rate of 2 GS s Therefore at the maximum sampling rate the digitizer can record a signal over a time period of up to 8 ms 16 Mpoints 0 5 ns point The time base range can be adjusted by varying the amount of acquisition memory or the sampling rate of the digitizer 3 6 3 Dual Bank Memory amp Buffered Sequence Acquisition Digitizers acquire waveforms in association with triggers Each waveform is made of a series of measured voltage values sample points that are made by the ADC at a uniform clock rate To maximize sampling rates and utilize memory as efficiently as possible the digitizers include both Single and Sequential storage modes The Buffered Sequence Acquisition mode allows the capture and storage of consecutive single waveforms Sequence Acquisition mode is useful as it can optimize the digitizer s sampling rate and memory requirements for applications where only portions of the signal being analyzed are important The mode is extremely useful in almost all impulse response type applications RADAR SONAR LIDAR Time of Flight Ultrasonics Medical and Biomedical Research etc Buffered Sequence acquisition enables successive events which can occur within a very short time to be captured and stored without loss A crucial feature of Se
