Measurement Rules

When performing measurements, precise relative timing and phase between the readout pulse and the acquisition is particularly important.

In order to provide this precision, LabOne Q and in some cases the underlying hardware pair readout and acquistions into a single tightly constrained operation.

These constraints result in the following rules being applied by LabOne Q when compiling measurements:

Rules

1. In each section with an acquire operation:

   1. There may be at most one acquire operation per signal.

   2. There may be at most one play operation per signal.

   3. All acquire operations on the same AWG must start at the same time.

   4. All play operations on the same AWG must start at the same time.

2. Measurements on the same AWG may not overlap unless:

   1. All their acquire operations start at the same time.

   2. All their play operations start at the same time.

3. For each pair of signals used for readout and acquisition, the delay between the readout and the acquisition must be constant throughout a LabOne Q experiment.

4. When using the pipeliner:

   1. Measurements must be performed on the same set of readout and acquisition signals in each chunk, and the handles used to store results in each chunk must match.

   2. The duration of the measurement operations for a given signal must be the same in each chunk.
