Agilent InfiniiVision 3000 X-Series Oscilloscopes User's Guide 69
For passive probes (such as the N2862A/B, N2863A/B, N2889A, N2890A,
10073C, 10074C, or 1165A probes), the Probe Check softkey appears; it
guides you through the process of compensating probes.
For some active probes (such as InfiniiMax probes), the oscilloscope can
accurately calibrate its analog channels for the probe. When you
connect a probe that can be calibrated, the Calibrate Probe softkey
appears (and the probe attenuation softkey may change). See "To
calibrate a probe" on page 70.

To specify the channel units
1 Press the probe's associated channel key.
2 In the Channel Menu, press Probe.
3 In the Channel Probe Menu, press Units; then, select:
• Volts — for a voltage probe.
• Amps — for a current probe.
Channel sensitivity, trigger level, measurement results, and math functions
will reflect the measurement units you have selected.
To specify the probe attenuation
This is set automatically if the oscilloscope can identify the connected
probe. See Analog channel inputs (see page 41).
The probe attenuation factor must be set properly for accurate
measurement results.
If you connect a probe that is not automatically identified by the
oscilloscope, you can manually set the attenuation factor as follows:
1 Press the channel key.
2 Press the Probe softkey until you have selected how you want to specify
the attenuation factor, choosing either Ratio or Decibels.
