The measurement interval for which the Code Domain Analysis metrics are calculated is given by:

Interval start - Start of the interval defined by an offset in slots relative to a synchronization event where the synchronization event can be configured to be at the first detected symbol, slot, or frame boundary within the acquired signal.

The synchronization event that the offset refers to is configured by the CDA Synchronization Mode property which can be set to Arbitrary, Slot, and Frame referring to symbol, slot, and frame synchronization, where:

  • Symbol synchronization refers to the synchronization to the first detected symbol boundary within the acquired signal where the symbol definition refers to symbols with largest spreading factor of 64 chips. That is, symbol synchronization synchronizes to a chip offset relative to the frame start being an integer multiple of 64 chips.
  • Slot synchronization refers to the synchronization to the first detected slot boundary within the acquired signal, where a slot is defined as a segment of the signal having a duration of 1.667 ms or equally 2048 chips. That is, slot synchronization synchronizes to a chip offset relative to the frame start being an integer multiple of 2048 chips.
  • Frame synchronization refers to the synchronization to the first detected frame boundary within the acquired signal where a frame is defined as the segment of the signal having a duration 26.67 ms or equally 16 slots or 32768 chips. The offset is configured by the CDA Measurement Offset property.

Interval Duration - Duration of the interval configured as length in terms of slots. The duration is configured by the Measurement Length property.
