Measurement Synchronization with LXI-B
Setting Up and Executing a List Sweep Measurement
frequency in its list. The MXA’s “WaitingForTrigger” instrument event
transitions high, and a “LAN1” output event goes onto the LAN with a
rising edge. The MXA waits for its next trigger.
The two instruments continue to step through their lists until the MXA
has completed measurements at every frequency in its list. Once the
final measurement has completed, the “OperationComplete”
instrument event transitions high, causing the “OperationComplete”
output event to go out onto the LAN with a rising edge. This event may
be caught by a controller to signal the end of the measurement. The
controller may then retrieve the list sweep measurement results from
the MXA.
Synchronizing a List Sweep Measurement Between
an MXA and an MXG
Synchronizing Using Peer to Peer messages
