NOTE. To ensure accurate measurements, warm up all test equipment according
to the manufacturer's recommendations before making any adjustments.
To adjust the probe low-frequency compensation do the following:
1. Connect the P6133 probe to the oscilloscope CH 1 input.
2. Set the oscilloscope controls for 100 mV (includes probe 10X attenuation),
1 ms, and DC coupling.
3. Use the hook tip to connect the probe to the oscilloscope calibrator output.
4. Set the triggering and amplitude controls for a stable display of approximate-
ly five square wave cycles and an amplitude of four divisions at center
screen.
5. Use the low-reactance nonconductive adjustment tool to adjust LF COMP
(low-frequency compensation) for the squarest waveform front corner edge.
Refer to Figures 8 and 9 for further details.
6. Disconnect the test setup.
To adjust the probe high-frequency compensation do the following:
1. Connect the positive fast-rise output of the calibration generator through the
BNC cable and 10X attenuator to the oscilloscope CH 1 input.
2. Set the oscilloscope controls for 10 mV, 20 ns, and 50
3. Adjust the pulse amplitude to produce a 5 division display on the oscillo-
scope.
4. Set the triggering controls for a stable display and center the waveform
on-screen.
5. Note the system aberrations for comparison in step 9.
6. Remove the BNC cable and 10X attenuator connecting the oscilloscope to
calibration generator. Connect the P6133 probe to the oscilloscope CH 1
input.
7. Connect the probe tip through the probe-tip-to-BNC 50
female BNC-to-BNC adapter (or the 50
adapter) to the positive fast-rise output of the calibration generator.
8. Set the oscilloscope coupling to the 1 M DC position.
