Teledyne LeCroy AP031 Differential Probe
The Teledyne LeCroy AP031 is a special differential voltage probe used for exacting oscilloscope measurements when working with noisy or dangerous industrial environments. This particular product is necessary for diagnosing many types of circuits and is most useful when there is a signal of interest that is referenced to a floating voltage (often over a hundred volts positive/negative of Earth ground). The AP031 will isolate your oscilloscope, protect the oscilloscope and you from electrical shock while also eliminating ground loop problems that would adversely affect the measurement accuracy of the oscilloscope.
This probe is designed to operate within very difficult environments such as those encountered when testing and/or measuring power electronics, motor drive circuits, industrial controls and/or switch mode power supplies. The primary function of the AP031 probe is to safely and accurately measure the differential voltage between two points on a circuit while actively rejecting large common-mode signals. By doing so it ensures the integrity of the measured signal and eliminates noise generated by stray currents or large voltage offset conditions relative to the oscilloscope ground. The probe then converts the differential signal into a single-ended output which is compatible with all grounded oscilloscope inputs.
The key operating characteristics of the AP031 probe include a bandwidth of 25 MHz and selectable attenuation ratios of 1:10 or 1:100; and the ability to measure differential voltages up to ±70V and ±700V respectively. The probe has a high common-mode rejection ratio (CMRR), is rated for Measurement Category III (CAT III) at 1000 VRMS and therefore suitable for use with measurements in a building installation environment. The probe is battery-powered, allowing for complete field-portability, or alternatively, may be powered through an optional adapter. Additionally, the probe was designed to provide maximum protection to the user with insulated leads, safety hooks with finger guards and strict voltage derating limits for high frequency signals. As such, the AP031 represents a safe and reliable method for obtaining accurate differential voltage measurements in many industrial automation and power system environments where conventional probes cannot be used safely and/or effectively.
