Combining channels (Interleaving -INT option) When ordered with -INT option, the U5303A ADC card supports the capability of combining the converters (and their memories) from two channels to analyze a single input channel. With this feature the maximum sampling rate and the maximum amount of acquisition memory are doubled.

    1.5   Calibration 1.5 Calibration The U5303A 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 15 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 18 Thanks to fast trigger rearm, the U5303A 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 U5303A's U5303A datasheet.
  • Page 19 The timebase range defines the time period over which data is being acquired. For example, the U5303A-M02-SR2 has a standard acquisition memory of 64 MS/ch and a maximum sampling rate of 1.6 GS/s (non-interleaved). Therefore, at the maximum sampling rate, the ADC card can record a signal over a time window of up to 41 ms (approx.
