Oscilloscope passive probes

The most widely used type of oscilloscope probe is the "passive probe". Passive probes are also the most rugged and economical of probes. There are no active components such as transistors or amplifiers in the probe and therefore passive probes do not need to be powered.

Passive probes are classified into the following different types.
  1:1 high Z passive probe 10:1 or 20:1 high Z passive probe 100:1 or 1000:1 high Z passive probe Resistive divider passive probe
Features a low capacitance coax cable with a BNC connector on one end and a probe on the other. * The most widely used scope probe type and is provided standard with most <1GHz oscilloscopes

* gives lower input capacitance and higher bandwidth than the 1:1 probe 
* additional attenuation for use with higher amplitude signals

* large attenuation requires a high gain amplifier on the scope
* highest bandwidth passive probe for measuring high-frequency, low-impedance circuit

* must be used with an oscilloscope’s 50Ω input 
When to use for viewing small signals (<1 V) for viewing up to ~300 V for viewing up to 15 kV high voltage high frequency low-impedance (50Ω) digital circuit, transmission line
When not to use for probing high frequency signal for achieving >600 MHz system bandwidth for making floating (ungrounded) measurement for probing high-amplitude, high-impedance signal
Typical Bandwidth up to 35 MHz up to 600 MHz up to 250 MHz up to 6 GHz
