  • Page 13: Calibration

    1.4   Calibration 1.4 Calibration The SA220P is factory calibrated and shipped with a calibration certificate. The internal calibration refers to the adjustment of ADC card internal parameters, corresponding to user selected parameters and required before starting acquisition. Internal calibration The internal calibration (or self-calibration) measures and adjusts the internal timing, gain and offset parameters between the ADCs and against a precise reference.
  • Page 14 The measured performance is then compared to published datasheet specifications. For each factory calibration, Acqiris tests the performance corresponding to all datasheet specifications, for every installed option. If needed, the DUT is adjusted and re-qualified ; ensuring it is in line with full specifications.

    (RADAR, SONAR, LIDAR, Time-of-Flight, Ultrasonics, Medical and Biomedical Research, etc.). In multi-record acquisition mode the acquisition memory is divided into a pre-selected number of records. Waveforms are stored in successive memory records as they arrive. Each waveform requires its own individual trigger. Acqiris SA220P User's Manual...
  • Page 19 Thanks to fast trigger rearm, the SA220P achieves very low “dead time” between the records of a multi-record acquisition. The “dead time” is the period after the end of an event when the card cannot accept a new trigger event. The re-arm time is provided in the SA220P datasheet.
  • Page 20 The timebase range defines the time period over which data is being acquired. For example, the SA220P has a standard acquisition memory of 4 GB, i.e. 1 GSample/ch and a sampling rate of 2 GS/s. Therefore, at the maximum sampling rate, the ADC card can record a signal over a time window of up to 500 ms /ch.
  • Page 21 (16, 32 or 64 bits). For the 14-bit SA220P, signed left-aligned 16-bit ADC code means that the signed raw ADC code is shifted to the left by 2 bits, and coded in 2’s complement to the final number of bits (16, 32 or 64) as illustrated below.
