30 6000 X-Series Oscilloscopes Service Guide
2 Testing Performance
2 Set up the oscilloscope.
a Adjust the horizontal scale to 200.0 us/div.
b Set the Volts/Div setting to the value in the first line in Table 8 (depending
on the oscilloscope model).
c Adjust the channel’s vertical position knob to place the baseline (reference
level) at 0.5 major division from the bottom of the display.
d Press the [Acquire] key.
e Then press the Acq Mode softkey and select Averaging.
f Then press the #Avgs softkey and set it to 64.
Wait a few seconds for the measurement to settle.

A blocking capacitor is required at this range to reduce noise. See “Use a Blocking Capacitor to
Reduce Noise" on page 33.

Full scale is defined as 16 mV on the 1 mV/div range. Full scale on all other ranges is defined as 8
divisions times the V/div setting.
