Extend high frequency probing applications
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 1 MΩ 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.
Probe with less error due to higher input impedance. For example,
in a 50 ohm system at 500 MHz, the 85024A presents 455 ohms
which produces a 10% signal loss from loading effects, while a
3 pF, 100 kΩ probe presents 106 ohms causing a 32% signal loss.
Spectrum analysis
Troubleshooting RF and IF signal paths to identify
problem areas in a system is convenient and accurate with an 85024A and a spectrum analyzer.
Measurements of frequency, power, modulation,
distortion, conversion loss, and spectral purity are
possible within a circuit. High sensitivity and low
distortion levels ensure the probe’s ability to detect
small signals or search for spurious responses. In
fact, the sensitivity of most 85024A applications is
limited only by the noise floor of the spectrum
analyzer itself. Add a tracking generator to easily
perform swept in-circuit measurements.
Troubleshoot IF paths for low level spurious responses.
Network analysis
When used with a network analyzer, this versatile
probe makes it easy to measure the gain, attenuation, phase linearity, or group delay of individual
circuit stages. Also, investigate multi-stage circuits
to rapidly determine the location of faults in a system. Low input capacitance and high shunt resistance minimizes the loading to the circuit under
test. Excellent frequency response and unity gain
of the Agilent 85024A guarantee high accuracy in
swept measurements.
Excellent flatness maintains accuracy in swept
measurements.
