WFM700 Series Waveform Monitors User Manual
Logging
The instrument contains two different log files: diagnostics and events. You can
use the Remote Web Server interface to download the contents of either log file.
This log contains the results of the last diagnostic test that was performed.
The instrument maintains an event log in which every entry is time-stamped with
the time-of-day when the instrument logged the event. When you enable
Timecode in the Video Inputs/Outputs submenu of the Configure menu, events
are time-stamped with the timecode embedded in the video signal.
CAUTION. The time-of-day time stamps in the Event Log are based on the system
time of the instrument when the logging process starts. If you update the system
time of the instrument while the Event Log is in the Running mode, the time
stamps will not start using the new system time setting. You must stop and restart
the Event Log before the time stamps will use the new system time.
Controlling the Size of the Event Log. The event log can contain up to 10,000
entries. Recording each individual event separately would quickly fill the log.
To handle this problem, the instrument classifies log entries as one of the
following:
H Single shot. One isolated occurrence is logged as one entry.
H Continuous. Uninterrupted sequence of occurrences is logged as two entries
marking the beginning and end of the sequence.
H Intermittent. Interrupted sequence of closely spaced occurrences can be
logged as separate entries or as one entry. Use the Printing/Event Log
submenu of the Configure menu to set the event log storage mode:
H Log for Duration. Logs intermittent events as one event to save space in
the event log.
H Log for Resolution. Logs intermittent events separately, which preserves
time stamp information for each event, but quickly fills up the event log.
By default, most of the possible alarms are enabled for logging. Use the
Configure Alarms submenu of the Configure menu to limit the number of
monitored error conditions.
