Offset Voltage FS 2 to Offset Voltage FS 2 Signals going outside of the FSR will be clipped and data values for the clipped portion of a signal should be regarded as erroneous The maximum input voltage for 50 Q input impedance is 5 V The maximum input for 1 MQ input impedance is 100 V dc ac except for the DC2x1A AR models where it is 300 V dc ac 3 2 7 Vertical Resolution The digitizers described in this manual use an ADC system with 8 bits of vertical resolution 256 levels The dynamic range of the ADC covers the Full Scale Range FSR of the Input Voltage setting For example if the Input Voltage is set to 1 V then the ADC resolution is equivalent to 3 91 mV To obtain the best dynamic range from the ADC care should be taken to ensure that the input signal varies over more than 50 of the Input Voltage FSR setting 3 2 8 DC Accuracy and Linearity The DP and DC Series digitizers use low noise front end electronics in order to ensure voltage measurement is made with accuracy and precision DC voltage accuracy at 0 V offset is better than 2 1 typical of the input voltage full scale The differential linearity is better than 0 7 LSB 0 8 LSB for DC135 DC140 digitizers and 0 9 LSB for other DC271 FAMILY digitizers 3 2 9 Using Probes The 50 Q and 1 MQ input impedance settings make it possible to use Acqiris digitizers with a wide variety of probes The 50 Q setting is most commonly used for active

5. 3 3 3 Single and Sequence Acquisition Modes 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 Single Acquisition mode is the normal operation of most digitizer products In this mode an acquisition consists of a waveform recorded with a single trigger The user selects the sampling rate and acquisition memory size and sets the number of segments to 1 default value The 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 In Sequence Acquisition mode the acquisition memory is divided into a pre selected number of segments Waveforms are stored in successive memory segments as they arrive Each waveform requires its own individual trigger The memory can be divided into any number of segments between 2 and 200 up to 8000 segments with options M32M M16M M8M and M4M 4000 segments
