4.4. Aborting Data Acquisition in MCS-32
1) Enter a new round of data acquisition presets
!
Click the MCS# radio button to return to MCS mode.
!
Select Pass Control... from the Acquire menu.
!
Set the Pass Length to 20.
!
Set the Pass Count preset to 1000.
!
In the Dwell Time section, set Bin Width to 1 second (the time unit from the list will
be seconds, s).
!
Click OK to close the dialog.
2) Clear the data and start an acquisition
!
Now the sidebar display is changing more slowly because the time unit is 1 second
instead of 1 microsecond. Notice that the current channel, displayed in the Channel field
on the sidebar, is incrementing slowly (once per second). Also, each time the Channel
value reaches 19, it returns to zero and the pass count increments.
!
Click the Auto button to scale the data. You should be able to see individual points
move as the MCS advances from one channel to the next. You are collecting exactly 1
count per channel.
!
You will notice that the Start radio button stays highlighted. It will remain highlighted
until the acquisition is completed. With the current settings, this will take 20,000
seconds (1000 passes × 20 channels/pass × 1 second/channel).
!
Since this exercise was introduced as a short tutorial, it’s time to abort the acquisition
and move on to explore yet another aspect of the MCS-32 software.
3) Abort the acquisition
!
Wait until the current channel is less than 10, then click the Stop button. You will notice
that the current channel keeps incrementing, and the Stop button starts flashing.
!
If you now wait (without clicking Stop again) for the channel to reach zero again, you’ll
see the mark in the Start button clear, while at the same time, the Stop button will stop
flashing and will now display the mark (dot).
