101. z will be accepted If you do this you may need to correct for the difference in your application since the digitizer and the driver have no way to know about such deviations The amplitude and threshold conditions for an External Reference are the same as for the External Clock If synchronization between several digitizers is required the reference signal should be applied to all of them User Manual Family of 10 bit Digitizers Page 38 of 60 acqiris 3 6 Internal Calibration The software drivers supplied by Acqiris include calibration functions for the timing gain and offset settings which can be executed upon user request The digitizers are never calibrated in an automatic way ie as a side effect of another operation This ensures programmers have full control of all calibrations performed through software in order to maintain proper event synchronization within automated test applications The digitizers include a high precision voltage source and a 16 bit DAC used to determine the input voltage and offset calibration For accurate time and voltage measurements it is recommended to perform a calibration once the module has attained a stable operating temperature usually reached within a few minutes of digitizer operation after power on Further calibration should not be necessary unless temperature variations occur A full internal calibration of a digitizer can be very time consuming gt 100 s digitizer in particular
