Agilent / HP 85024A

The Agilent / HP 85024A high frequency probe offers excellent performance which employs a GaAs IC to obtain extremely low input capacitance of only 0.7 pF shunted by 1 M ohms of resistance.

Because of this low input capacitance, high frequency probing is possible without adversely loading the circuit under test. Also, the 1 M ohms shunt resistance guarantees minimal circuit loading at lower frequencies.

Since the 85024A 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 / HP RF network or spectrum analyzers which supply probe power from the front panel.

The 85024A probe when used with a network analyzer, makes it easy to measure the gain, attenuation, phase linearity, or group delay of individual circuit stages. Excellent frequency response and unity gain of the Agilent / HP 85024A guarantees high accuracy in swept measurements.

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 85024A 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. A tracking generator can be added to 85024A to easily perform swept in-circuit measurements.

Simplicity and reliability are inherent in the design of the 85024A. The front end was designed using a custom GaAs IC to provide low input capacitance.

A retractable metal sleeve protects the probe from physical damage to the tip when not in use and, more importantly, from electrostatic discharge (ESD) damage to the 85024A probe. By retracting the metal sleeve, the user establishes himself at the same potential as the high frequency probe.

Direct compatibility with many RF analyzers further leverages the performance and flexibility of the 85024A high frequency probe.
