How do I connect an oscilloscope probe to an oscilloscope?
Do you know how oscilloscope probes are connected to an oscilloscope? Since there are many types of oscilloscopes and probes, let's take a mixed-signal oscilloscope (MSO) as an example to introduce the connection of oscilloscope probes.
1 If necessary, switch off the power of the device under test.
Switching off the power supply of the equipment under test only prevents possible damage caused by accidental short-circuiting of the two power cables when connecting the probe. Since there is no voltage display on the probe, power can be maintained to the oscilloscope.
NOTE: CAUTION Probe cables for digital channels - Use only the Keysight Logic Probe and Accessory Kit that came with your mixed-signal oscilloscope.
2 Connect the digital probe cable to the DIGITAL Dn - D0 connector on the mixed-signal oscilloscope. The digital probe cable is fitted with a fixed connector, so it can be connected in only one way. You do not need to switch off the oscilloscope.
The MSO cable has an operating temperature range of 0°C to 55°C and its non-operating (storage) temperature range is -40°C to 70°C.
3 Use the probe clamps to connect ground leads to each set of channels (per group). Using a ground lead improves the fidelity of the signal transmitted to the oscilloscope and ensures accurate measurements.
4 Connect the clip to one of the probe leads (the other probe leads are ignored in the diagram for a clearer view).
5 Connect the clamp to a node in the circuit to be tested.
6 For high-speed signals, connect the earth lead to the probe lead, the clamp to the earth lead, and the clamp to the device under test and ground.
7 Repeat the above steps until all relevant points are connected.
