When the probe is powered on, all LEDs briefly
flash as the self-test routine runs, and then the
following LEDs remain lit:

The TriMode feature allows you to view
two single-ended signals and the resultant
differential waveform and common-mode
voltage without moving the probe connection.
Press the Input Mode button to cycle through
the waveform views.
This example shows a typical HDMI signal (one
half-lane) on the A and B inputs. The resultant
differential waveform and common-mode
voltage are shown.

Functional Check and Calibration
Functional Check and Calibration
After you connect the probe to the oscilloscope, perform a functional check using the calibration board included with the probe.
CAUTION.
To avoid ESD damage to the probe, always use an antistatic wrist strap (provided with your probe), and work at
a static-approved workstation when you handle the probe.
Functional Check
This procedure checks the four TriMode settings on the probe, using the PROBE COMPENSATION or FAST EDGE connection on
the front panel of the oscilloscope. The A-B (differential mode) is set up and verified first, and then the remaining input modes are
checked and compared to the differential mode measurement.
