Agilent 10400B Series Miniature Passive Oscilloscope Probes
Bandwidth considerations
Bandwidth considerations
The dominant probe limitation to system bandwidth is its input capacitance,
assuming that the high-frequency compensation adjustments have been made.
The displayed bandwidth of any measurement system using an oscilloscope and
probe is determined by four factors: probe input capacitance, source impedance,
source bandwidth, and oscilloscope bandwidth.
