How the Oscilloscope Works
System Bandwidth
Because of the physical geometry of this type of probe and because the
divider does not have to be capacitively compensated, this type of probe has
the lowest capacitive loading of any probe. This low capacitance and its
inherent wide bandwidth make it best suited for wide bandwidth
measurements or those measurements where timing is the most critical
parameter.
The disadvantage of this type of probe is its relatively heavy resistive loading.
Not all circuits can drive 500 Ω or 1 kΩ. Even for measurements in a
relatively low impedance circuit, the amplitude errors can be significant.
Changes in bias levels or operating current in the circuit under test might
affect the circuit's behavior.
This type of probe is the best choice for minimum disturbance probing of
ECL circuits and 50-Ω transmission lines. The 1-kΩ divider probes are also
usually suitable for high-speed CMOS circuits. If you are interested in
troubleshooting CMOS, consult the data sheet for the particular CMOS part
to make sure that it can drive a 1-kΩ load and to determine what the voltage
error would be.
Compensated Passive Divider Probes This is the most common type
of oscilloscope probe. The 900-kΩ resistor in the tip forms a 10:1 voltage
divider with a 111-kΩ resistor in parallel with the 1-MΩ input resistance
of the oscilloscope. Some versions use a 9-MΩ resistor at the tip; the
oscilloscope's input resistance forms the other part of the voltage divider.
