Using IO Interfaces
Using LAN
Peer to Peer Messaging
The MXA and MXG are capable of sending and receiving LXI specific LAN packets. The packets are
configurable, and may be sent when various instrument events occur during a measurement or state
recall. Each instrument event has an associated sense of 0 or 1 to indicate whether or not the event
is active. The instrument events that can cause an MXG to send an LXI LAN packet are summarized
in the table below.
Table 2-1 LXI LAN Packets
Enabling the LXI Event Subsystem
Due to the high priority response time demands of handling events, enabling the LXI event subsystem
can adversely impact certain specifications such as frequency and power switching speed. This
becomes more noticeable at higher rates of LXI event traffic. By default, the subsystem is disabled.
To enable the LXI event subsystem from the front panel:
• Press Utility > More > LXI–B > LXI–B Enabled
To enable or disable the LXI event subsystem from SCPI:
• :LXI:STATe ON|OFF
NOTE The LXI Event subsystem state is a persistent instrument state; it is not affected by normal
preset operations.

Instrument Event Description
OperationComplete
Indicates whether or not an operation is
underway.
•
•
•
•
Settling Indicates the instrument is settling.
Sweeping
Indicates whether or not the instrument is
currently performing a sweep.
Waiting For Trigger Indicates whether or not the instrument is
waiting for a trigger event before a measurement
begins.
For example, a single sweep will result in:
OperationComplete = 1 before the sweep.
OperationComplete = 0 during the sweep.
OperationComplete = 1 after the sweep.
