HP / Agilent 85024A High Frequency Probe
The Agilent Technologies 85024A high frequency probe
offers excellent performance. The probe employs a GaAs
IC to obtain extremely low input capacitance of only
0.7 pF shunted by 1 MΩ of resistance. Because of
this low input capacitance, high frequency probing is
possible without adversely loading the circuit under
test. Also, the 1MΩ shunt resistance guarantees
minimal circuit loading at lower frequencies. Since
the probe has excellent sensitivity, it is well-suited
for use with analyzers offering exceptional dynamic
range. The 85024A is an excellent accessory for high
frequency test equipment, especially Agilent RF
network or spectrum analyzers which supply probe power from the
front panel.
