HP 10400A OPERATING NOTE
BANDWIDTH CONSIDERATIONS
The HP 10400A Miniature Probes span three
bandwidths. The HP 10430A/31 A/41 A are
designed for use with oscilloscopes having
bandwidths of up to 500 MHz. The HP
10432A/33A/35A/40A are designed for
oscilloscopes with bandwidths up to 300 MHz,
and the HP 10434A/36A are used with
oscilloscopes with bandwidths up to 100 MHz.
The dominant probe limitation to system
bandwidth is its input capacitance, assuming
the high-frequency compensation adjustments
have been made. 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.
The system bandwidth when using the 50 ohm
probes {10437A/42A/43A) with a 50 ohm test
source is generally the bandwidth of the
oscilloscope up to 1 GHz approximately.
Table 2 is a list of the HP 10400A probes and
the specifications of oscilloscopes that are
compatible with the probes.
