Input signal into Channel #1 

A trigger should be produced and the capture continues to the end.  While 
capturing, you should have seen the waveform for Channel #1 go from a zero 
baseline in the center of the channel to a sine wave within the grid on both the 
color display and the chart. 

 

 

Note:  you do not need to run the chart when you capture data.

Data Review 

 

    

DISCUSSION

  

 

 

Data capture records can be reviewed on the color display as well as on the 

 

 

chart paper.  Typically, the review is done on the display and then sections of 
interest are printed on the paper.  During review, the timebase can be expanded 
or compressed to give appropriate detail of the signal.

[SET PLAYBACK WINDOW] [CHANGE METHOD]

  

Turn encoder wheel

[SET START POINT]

  

Turn encoder wheel to 15%. 

 

[SET END POINT]

  

Turn encoder wheel to 25%.

[SET EXPANSION]

  

Set t-expansion: 

x

1/2.  Note that you can expand or 

compress the timebase for data playback to the chart.  For long data records, it 
is suggested to use maximum compression for the first playback to conserve chart 
paper. Then, expand the playback to get the detail you need.  As you change the 
starting and ending points from 100%, you can expand the playback timebase.
