c Press the Acquire key. Then press the Averaging softkey and
set #Avgs to 64.
Wait a few seconds for the measurement to settle.
2 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.
3 Use the BNC tee and cables to connect the oscilloscope
calibrator /power supply to both the oscilloscope and the
multimeter (see Figure 3).
