Network node apparatus for use in a stimulus-response sensing measurement, network containing such an apparatus and measurement method using such a network
Abstract
A network for performing a stimulus response experiment, for example to
measure a propagation delay between different locations on an object
contains a node apparatus and a further node apparatus. The node
apparatus performs stimulus generation and a further node apparatus
performs sensor data capture. The node apparatus comprises a handling
circuit configured to control timing of stimulus generation based on a
trigger signal. The experiment is prepared in a computer of the node
apparatus. The computer supplies a command to a transmitter circuit to
command the transmitter circuit to transmit a message to the further
node apparatus. The transmitter circuit is used both to transmit the
message in response to the command and to generate the trigger signal in
a predetermined relation to a time of transmission of the message. Thus,
accurate coordination timing is ensured in spite of possible
inaccuracies in the preparation control circuit.
