    1.5   Calibration 1.5 Calibration The SA230E is factory calibrated and shipped with a calibration certificate. The internal calibration refers to the adjustment of ADC module 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 16 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.

  • Page 19 Thanks to fast trigger rearm, the SA230E 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 module cannot accept a new trigger event. The re-arm time is provided in the SA230E's SA230E datasheet.
  • Page 20 The timebase range defines the time period over which data is being acquired. For example, the SA230E has a standard acquisition memory of and a sampling rate of 4 GS/s. Therefore, at the maximum sampling rate, the ADC module can record a signal over a time window of up to 500 ms.

    —————————————————————— 9.2 Q. How to manage the internal temperature? A. The operating temperature of the SA230E as specified in the SA230E datasheet, is the workstation internal ambient temperature at intake of the ADC module. The effective temperature limit is fixed by the maximum internal DPU temperature which should stay below 100°C to guarantee FPGA proper operating.
