4 - 8 HOW TO USE THE INSTRUMENT
CAL SIGNAL AND PROBE ADJUSTMENT
Each measuring probe has been checked and adjusted before delivery. However,
to match the probe to your oscilloscope, you must perform the following
procedure to optimize the pulse response of the combination of oscilloscope input
and probes.
- Connect the probe body to channel 1.
- Connect the probe tip to the Probe Adjust output of the oscilloscope.
- Press the AUTOSET key.
If the display looks like one of the two displays shown on the left, you must adjust
your probe to get the display shown on the right.
The probe output impedance can be adjusted through a hole in the compensation
box of the probe to obtain optimum pulse response. Refer to the following figure.
- Adjust the probe until the screen shows the correct compensation.
The probe is now adjusted for optimum pulse response with this oscilloscope. If
you connect the probe to another channel or oscilloscope, it must be adjusted
again to that oscilloscope input.
- Repeat this adjustment for the second probe.
