RS PRO Oscilloscope Probe, 1:10, 1:100

The RS-SI 9001 oscilloscope probe from our own trusted and reliable brand RS PRO, is an active differential probe which allows safe and accurate measurements between two voltage signals that are referenced to each other. The RS-SI 9001 features switchable attenuation of 10:1 and 100:1, 25 MHz bandwidth and ±700 V maximum differential. The probe is also compatible with all oscilloscopes from numerous manufacturers which have 1MOhm BNC input. The probe can be operated either by 4xAA batteries or by the supplied USB power lead, which is needed to powerup the active devices within the probe.

An oscilloscope probe is an essential device for use with an oscilloscope when carrying out a range of tests and measurements of electrical devices. The two main types of oscilloscope probes are active and passive, both with varying bandwidths and are commonly used by electrical engineers.

What is a differential oscilloscope probe?

A differential probe is an active probe that features both negative and positive inputs, as well as a separate ground lead. Differential probes are popular for measuring high-frequency signals or signals of very low amplitude. It drives a single terminated 50Ω cable to transmit its output to one oscilloscope channel.

What is oscilloscope bandwidth?

The bandwidth of an oscilloscope specifies the usable frequency range of the oscilloscope. The signal processing circuitry of an oscilloscope acts like a low pass filter, limiting the frequency behaviour of the device. Therefore, for a proper analysis, the oscilloscope bandwidth must be considerably higher than the frequency of the signal under test.

How to select the correct oscilloscope probe?

When selecting the correct probe, make sure the probe’s capacitance is within the measuring range of the oscilloscope. Active probes have the ability to support much higher signal bandwidths, which is why they tend to be favoured by most engineers when used in higher performing applications.

What is an active probe?

An active probe is different from a passive probe as they contain a small active amplifier built into the body near the probe tip, ensuring minimal probe input capacitance. An active probe is also the least intrusive of all probes due to a significantly lower capacitive loading whilst providing greater accuracy.
