Testing Performance
To verify voltage measurement accuracy
b Set the Volts/Div setting to the value in the first line in Table 3-5.
Table 3-5
Settings Used to Verify Voltage Measurement Accuracy
c Press the Acquire key. Then press the Averaging softkey and set #Avgs to 64.
Wait a few seconds for the measurement to settle.

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.
