3. Then choose th
e acquisition mode on the
side menu. You can chose from: Sample,
Peak Detect, Hi Res, Envelope, or Average.
NOTE. Peak Det
ect and Hi Res modes
take advantage of sample points that the
oscilloscope would have d iscarded at lower
sweep speeds
. Therefore, these modes only
work when the current sample rate is less than
the maximum possible sample rate. As soon
as the oscil
loscope starts to acquire at the
maximum sample rate, then the Peak Detect,
Hi Res and Sample modes all look the same.
You can con
trol the sample rate by setting the
Horizontal scale and the Record Length.
