How to acquire data
When you start to acquire LA begins sampling data from the probes. Then each time
clock occurs the data will be sampled.
Then sampled data is sent to trigger function block and store in main memory. The
trigger program checks specific events with the sampled data and take specific action. The
trigger program can check events as rising edge, data values, and data ranges etc. LA
module enables a post trigger delay counter when trigger reach specified value and to
allow post trigger portion of the acquisition memory to fill before data acquisition stops.
Press “
F
” to get into data acquisition mode after finish setting for trigger and
sampling. Then running status display as “
RUN
” and running status display “
TRIG
”
when detected trigger signal and display “
STOP
” when data acquisition finished. Then
you can start to analyze data. Data acquisition can be stopped by press “
F
” again during
the process.
Note:
When running status display as “RUN”
、
“TRIG” during data acquiring
process ,only "F" key for operate and other keys or knobs are idle. Only till status
display as "STOP" then others operation are working.
