e2v semiconductors SAS 2010

4.5.8.

Acquisition

For start acquisition you use the stream function

•

Snap: for single acquisition

•

Start for continuous acquisition, (stop acquisition with the stop button)

When you launch acquisition several window results appear

CH_A => ADC channel A

CH_B => ADC channel B

CH_C => ADC channel C

CH_D => ADC channel D

Sample signal: example of signal in simultaneous channel
