Using the Probes
Refer to the oscilloscope’s online help for information on Multipurpose functions.
No Action
Disables the probe button.
Probe Attenuation Ratio
The probe’s attenuation ratio can be set to 2:1 or 10:1. When you attach the probe
to the Infiniium oscilloscope, the AutoProbe interface automatically sets the probe
attenuation to the value necessary to make the dynamic range of the probe
greater or equal to the level required to measure the current input signal.
Functional Test
Use the following generic measurement procedure to ensure that your probe is
functioning properly.
1 Connect the probe to an oscilloscope channel input and ensure the input
impedance of the oscilloscope matches the output impedance of the probe
(50
W
).
2 On the oscilloscope, click Utilities > Calibration Output to assign probe
compensation (Probe Comp) to the AUX Output connector.
3 Connect the probe tip to the oscilloscope’s front-panel AUX Output connector.
4 Press the oscilloscope’s [Auto Scale] button.
5 If the probe is functioning properly, a square wave should now be displayed on
the oscilloscope.
