Calibrating the Infiniium Oscilloscope and Probe
17 Select the Start Skew Calibration... button and follow the on-screen instructions.
18 Set the vertical scale for the displayed channels to 100 mV/div.
19 Set the horizontal range to 1.00 ns/div.
20 Set the horizontal position to approximately 3 ns.
21 Change the vertical position knobs of both channels until the waveforms overlap each other.
22 Select the Setup menu choose Acquisition... from the pull-down menu.
23 In the Acquisition Setup dialog box enable averaging. When you close the dialog box, you should
see waveforms similar to that in

probes between channels or other oscilloscopes, or it will be necessary to calibrate them again. It
is recommended that the probes be labeled with the channel on which they were calibrated.
