NI-SCOPE

Call Probe Compensation Signal Start.

4.

In InstrumentStudio, configure the settings of the input channel to which you connected
the probe.
a)

Set the channel to 

On

 to display the signal.

b)

Set the 

Input impedance

 of the channel to 

1 MΩ

.

c)

Match the 

Probe attenuation

 setting to the setting on your probe.

5.

Adjust the vertical range on the input channel until the signal starts to clip and then
increase the vertical range by one step so that it no longer clips.

This process ensures you are using the maximum dynamic range of the ADC.

6.

Examine the digitized signal and adjust the tunable capacitor on the probe.

The probe is correctly compensated when the waveform appears as square as possible:

Probe Adjustment Signal

Probe Adjustment Signal

Probe Adjustment Signal

Compensated Correctly

Undercompensated

Overcompensated

Proper Amplitude of a

1 MHz Test Signal

Reduced Amplitude of a

1 MHz Test Signal

Increased Amplitude of a

1 MHz Test Signal

Once compensated, the probe conveys signals to the input channel accurately, without
artificially attenuating or amplifying frequency components of the signal.

Tip

 

For the most accurate measurements:

Compensate probes for each channel of the oscilloscope;

Use a compensated probe only with the channel you used to compensate it; and

Compensate your probes frequently.
