Testing Performance
2
Set up the oscilloscope.
a
Adjust the horizontal scale to
200.0 us/div
.
b
Set the Volts/Div setting to the value in the first line in
(depending
on the oscilloscope model).
c
Adjust the channel’s vertical position knob to place the baseline (reference
level) at 0.5 major division from the bottom of the display.
d
Press the
[Acquire]
key.
e
Then press the
Acq Mode
softkey and select
Averaging
.
f
Then press the
#Avgs
softkey and set it to 64.
Wait a few seconds for the measurement to settle.

Full scale is defined as 16 mV on the 1 mV/div range. Full scale on all other ranges is defined as 8
divisions times the V/div setting.
