HP 54701A 2.5 GHz Active Probe

For nonintrusive, faithful reproduction of your signal, use the HP 54701A high-impedance 2.5 GHz active probe. Combined with the HP 54700 family of oscilloscopes, or the HP 83480A Digital Communications Analyzer, you get the accuracy you need for your most challenging measurements. The HP 54701A is directly powered by the HP 54700 family of oscilloscopes or the HP 83480A Digital Communications Analyzer.

The HP 54701A also extends probing bandwidth response of frequency domain instruments, such as spectrum analyzers and network analyzers, down to dc so that their full capabilities can be realized. The HP 54701A, powered by the HP 1143A Probe Offset Control and Power Module (ordered separately), is versatile enough to be used with any test and measurement equipment with 50 ohm input. The HP 1143A is capable of powering 2 HP 54701A probes.

The HP 54701A active probe offers digital designers 2.5 GHz of bandwidth for extending measurement response, along with 140-ps rise time for accurate measurement of fast signals. Adding 1% long-term flatness and ±0.5 dc gain accuracy results in a clearer representation of the input signal than ever before possible; unlike that of any other high bandwidth probe. As frequency increases, probe tip capacitance decreases the impedance of the probe by Xc = 1/(2PifC), resulting in measurement error, depending on the source impedance of the output device. The HP 54701A's low tip capacitance becomes a distinct advantage as frequency increases.

The HP 54701A's microcircuits are protected by their ability to withstand damage from high input voltage, ESD pulses, and shock to the probe tips. You'll appreciate the reliability and ruggedness of the HP 54701A. A 200-Vac maximum input tolerance means that there's no need to worry about damaging the probe if the tip comes in contact with a 120-Vac line. Accidental static discharge is less of a reliability concern for precision, high-bandwidth probes with the HP 54701A's +/-12-kV ESD protection. The HP 54701A's probe tip is rigid enough for probing, but pliable enough to bend if dropped, protecting the probe's microcircuits from damage. In addition, the tips are easy and inexpensive to replace.

When the HP 54701A is used with any HP 54700-series oscilloscope or the HP 83480A Digital Communications Analyzer, the offset applied to the probe is directly controlled with the offset control in the Channel menu.

This active probe will significantly increase the performance of your oscilloscopes, logic analyzers, counters and other time-domain electronic test equipment.
