c Press the [Acquire] key.
d Then press the Acq Mode softkey and select Averaging.
e Then press the #Avgs softkey and set it to 64.
Wait a few seconds for the measurement to settle.
3 Press the [Cursors] key, set the Mode softkey to Normal,
then press the XY softkey and select Y. Press the Y1
softkey, then use the Entry knob (labeled on the
front panel) to set the Y1 cursor on the baseline of the
signal.

A blocking capacitor is required at this range to reduce noise. See “Use a
Blocking Capacitor to Reduce Noise” on page 44.

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