Measurement Synchronization with LXI-B
Setting Up and Executing a List Sweep Measurement
31. Begin the MXA's list
sweep
32. Wait for the
"OperationComplete"
instrument event
33. Read measurement
results.
Synchronizing Using Alarm Triggers
A second method of synchronization uses alarm triggers to step each
instrument through their lists at predetermined times. Using this
method, the instruments never have to communicate their states.
Instead, the controller determines a schedule for execution, and each
instrument carries out its actions with the assumption that the other is
keeping up with its schedule. The following example illustrates a
method for setting up a list sweep using alarms for synchronization.
Task
1. Disable LXI Output
LAN Events on the
MXG
2. Reset the MXG
3. Choose the MXG's
PTP domain

:INIT:LIST
Detect the peer to peer traffic
using Interactive LXI. To
programmatically listen for LXI
peer to peer messages, use the
IOLibraries TMFramework LXI
library.

This command is sent
to the MXA.
This will cause the
MXA to take a
measurement at the
first frequency in its
list. It will also begin
waiting for the alarm to
fire before moving on to
the next measurement.
When the MXA has
completed its list, it will
send the peer to peer
message
"OperationComplete"
with a rising edge.
This query is sent to
the MXA.
