Specifies the synchronization mode for the ModAcc measurement.

You do not need to use a selector string to configure or read this property for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals.

The default value is Slot.

The following table lists the characteristics of this property.

Resettable Yes
Slot 0

The measurement uses the slot synchronization mode. The slot boundary in the acquired signal is detected, and the measurement is performed over the number of slots specified by the ModAcc Meas Length property, starting at the offset from the boundary specified by the ModAcc Meas Offset property.

If you set the Trigger Type property to Digital Edge, you should provide the trigger at the start of the slot from which the ModAcc Meas Offset property should be considered. If you set the Trigger Type property to IQ Power Edge, it is required that the received signal has either one traffic time slot or contiguous traffic time slots. Additionally, for this trigger type, the traffic time slot(s) in the received signal should be contiguous with the pilot time slot, if the pilot time slot is present.
Subframe 1

The measurement uses the subframe synchronization mode. The first subframe boundary in the acquired signal is detected, and the measurement is performed over the number of slots specified by the ModAcc Meas Length property, starting at the offset from the boundary specified by the ModAcc Meas Offset property.

If you set the Trigger Type property to Digital Edge, you should provide the trigger at the start of the subframe. If you set the Trigger Type property to IQ Power Edge, it is required that the received signal has either one traffic time slot or contiguous traffic time slots. Additionally, the traffic time slot should be contiguous with the active pilot time slot.
