Probe Compensation
Performance G raphs
Due to variations in oscilloscope input characteristics, the
low-frequency compensation of the probe may need adjustment
(in 10X attenuation only) after moving the probe from one
oscilloscope channel to another.
If a 1 kHz c alibrated square wave displayed at 1 ms/division
shows significant differences between the leading and trailing
edges, perform the following steps to optimize low-frequency
compensation:
1. Connect the probe to the calibration signal on the
oscillosco
pe front panel.
WARNING. To avoid electric shock, only connect to the
Probe Comp s
ignal on the oscilloscope when making this
adjustment.

2. Press AUTOS
ET or otherwise adjust your digitizing
oscilloscope to display a stable waveform.
3. Adjust the trimmer in the probe until you see a perfectly
flat-top square wave on the display. (See i llustration.)
WARNING. To avoid electric shock, only use the insulated
adjustment tool when making compensation adjustments.
