1 Press [Save/Recall] > Default/Erase > Factory Default to recall the factory default
setup.
2 If you are testing a 2000 X-Series oscilloscope, set the probe attenuation to 1:1
on the analog channel you are testing (for example, [1] > Probe > Probe ; then,
turn the Entry knob to select 1.00 : 1 ).
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 in Table 8 or Table 9
(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.

A blocking capacitor is required at this range to reduce noise. See “Use a Blocking Capacitor to
Reduce Noise" on page 34.

Full scale is defined as 32 mV on the 2 mV/div and the 1 mV/div range. Full scale on all other ranges
is defined as 8 divisions times the V/div setting.
