7.3 Recording Control Settings
The Recording Settings control the parameters of the High Speed Recording,
Low Speed Recording and Trend Logging.
For High Speed and Low Speed Recording the TESLA recorder can create up
to three records simultaneously. The TESLA employs sophisticated trigger
combination algorithms used to combine data from multiple events into a sin-
gle record and also to reduce the amount of redundant data in the records. In
addition, the TESLA will combine data captured using multiple time-frames
into a single record.
In the TESLA there are two modes of capturing data; Edge Recording and Du-
ration Recording. Both modes are available for High Speed Recording, only
Edge Recording is available for Low Speed Recording.
Edge Mode
Figure 7.4: Recorder Setup Utilities - Edge Recording
In Edge Recording, the rising edge of the trigger is used to create a record that
has a set amount of pre-trigger data and a set amount of post-trigger. This is
known as a normal length record. If another trigger is processed while the re-
cord is being created, the record may be extended to the full normal length of
data associated with the new trigger. Multiple extensions can occur up to the
Maximum Record Length limit. Records with combined High Speed and Low
Speed data can only be extended during the High Speed data capture portion
of the record.
Edge Recording mode tends to create smaller records that contain useful fault
data around the start of the trigger, but may not capture data for the entire du-
ration of the trigger.
