# Are oscilloscope probes interchangeable?

## Are oscilloscope probes interchangeable?

In general: yes the probes for these generic oscilloscopes will work across different oscilloscopes. What you need to pay attention to is that the probes need the input of the oscilloscope to have an input impedance of 1 Mohm.

## Why oscilloscope probe has adjustment for capacitor?

The oscilloscope probe contains a variable capacitor that is used to “tune” the probes cable and distributed capacitance to match the input impedance of the scope. Failure to properly adjust this capacitor could result in distorted waveforms and incorrect measurement values.

What function does the x1 and x10 switch on the oscilloscope probe perform?

Use x1 probe to measure very low amplitude signals in low impedance circuits. Use 10x to measure everything else, especially if the circuit being measured is higher impedance.

### Why are oscilloscope probes so expensive?

Test equipment is hardly mass market. Another reason why the named brand probes are expensive problem is that mould tools to make all the little plastic parts are incredibly expensive so if you don’t sell many the tooling costs make up a large part of the purchase price.

### What does 10X probe mean?

A 10X oscilloscope refers to a probe with an integrated attenuator that delivers an attenuation of 10. This allows the circuits’ impedance to be enhanced by a factor of 10. While the 10X probe is attenuating the signal, it can also reduce the signal entering the oscilloscope.

What happen if the probe is at Undercompensate or overcompensate state?

A probe is properly compensated when the tops of the compensation signal are essentially horizontal. Overcompensated probes create overshoot on the leading edge of the signal, and undercompensated probes cause undershoot on the leading edge.

## What is the difference between 1x and 10X probe?

A probe’s attenuation factor (i.e. 1X, 10X, 100X) is the amount by which the probe reduces the amplitude of the oscilloscope’s input signal. A 1X probe doesn’t reduce or attenuate the input signal while a 10X probe reduces the input signal to 1/10th of the signal’s amplitude at the scope input.

When would you use a differential probe?

A differential probe is used to look at signals that are referenced to each other instead of earth ground and to look at small signals in the presence of large DC offsets or other common mode signals such as power line noise.
