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
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.
3 Use the BNC tee and cables to connect the oscilloscope
calibrator /power supply to both the oscilloscope and the
multimeter (see
Figure 3 ).
