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.
4 Press the [Cursors] key, set the Mode softkey to Normal , then press the X Y 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.
5 Use the BNC tee and cables to connect the precision source /power supply to
both the oscilloscope and the multimeter (see Figure 5 ).

A blocking capacitor is required at this range to reduce noise. See “Use a Blocking Capacitor to
Reduce Noise" on page 39.

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.
