2 Testing Performance
3 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 and column of Table 5.
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.

A blocking capacitor is required at this range to reduce noise. See “Use a Blocking Capacitor to
Reduce Noise" on page 23.

Full scale is defined as 8 mV on the 500 uV/div range. Full scale on all other ranges is defined as 8
divisions times the V/div setting.
