Event log descriptions
Column title Description Example
Received Time
• Displays the date and time of the LAN trigger
occurred
• Displays the value in UTC, 24-hour time
06:56:28.000 8 May 2008
EventID
Identifies the lan.trigger[N] that generates an
event
LAN0 = lan.trigger[1]
LAN1 = lan.trigger[2]
LAN2 = lan.trigger[3]
LAN3 = lan.trigger[4]
LAN4 = lan.trigger[5]
LAN5 = lan.trigger[6]
LAN6 = lan.trigger[7]
LAN7 = lan.trigger[8]
From Displays the IP address for the device that
generates the LAN trigger
localhost
192.168.5.20
Timestamp A timestamp that identifies the time the event
occurred; the timestamp uses the following:
• PTP timestamp
• Seconds
• Fractional seconds
The Model 2651A does not support
the IEEE Std 1588 standard. The
values in this field are always 0
(zero).
HWDetect Identifies a valid LXI trigger packet LXI
Sequence Each instrument maintains independent sequence
counters:
• One for each combination of UDP multicast
network interface and UDP multicast
destination port
• One for each TCP connection
Domain Displays the LXI domain number.
• The default value is 0 (zero)
0
1523
Flags Contain data about the LXI trigger packet Values:
• 1 - Error
• 2 - Retransmission
• 4 - Hardware
• 8 - Acknowledgments
• 16 - Stateless bit
Data The Model 2651A does not support the
IEEE Std 1588 standard; the values in this are
always 0 (zero)
Accessing the event log from the command interface
The event log can be accessed from any remote command interface. The event log must be enabled
before LXI trigger events can be viewed. To enable the event log, send:
eventlog.enable = 1
To view the event log from a remote interface, send:
print(eventlog.all())
