Manual Overview

The LeCroy AP034 Active Differential Probe manual provides detailed instructions for proper operation and connection to test instruments and circuits. To connect the probe to a LeCroy oscilloscope with ProBus, attach the probe output to the oscilloscope input, which automatically sets the termination and activates control functions. For instruments without ProBus, use the ADPPS power supply and ensure the output is terminated with a 50 Ω load for accurate gain calibration. When connecting to a test circuit, both inputs must be connected for accurate measurements, and the ground connection is optional. To minimize noise and maintain high performance, use short, twisted leads and match the input paths for common mode rejection. The manual advises against using incompatible attenuators, as this can affect transient response. Proper grounding is crucial; grounding can improve waveform fidelity but may introduce noise in some cases. The probe’s high impedance minimizes circuit loading, but care is needed at high frequencies due to capacitive reactance.

Quick Issues Covered

• Diagnose ESD-related damage in AP034 Active Differential Probe.
• Calibrate gain with correct 50Ω termination for accurate measurements.
• Trace circuit schematics using probe's input model for high-frequency accuracy.

Operation

The AP034 Active Differential Probe should be handled carefully to avoid damage from electrostatic discharge (ESD). When connecting the probe to a LeCroy Oscilloscope with ProBus, attach the probe output connector to the oscilloscope input connector, which will automatically recognize the probe and set the necessary parameters. For instruments without ProBus, use the ADPPS Power Supply and connect it to the probe output connector. Ensure the output is terminated correctly to maintain calibrated gain.

To connect the probe to a test circuit, use both the + and – inputs for accurate measurements, with the ground connection being optional. To maintain performance, minimize parasitic capacitance or inductance by using short connection leads and twisting them to reduce loop area. Use the same length and type of wire for both input connections to maintain high common mode rejection.

For AC coupling, install the AC coupling accessory on the probe tip. If the test circuit voltage exceeds the probe’s capability, use the external +10 or +20 attenuator, ensuring the correct order of installation if both the attenuator and AC coupler are used. The external attenuators are specific to the probe model and should not be interchanged.

The probe input connectors can mate with standard square pins, and included accessories help connect the probe to the test circuit. The probe’s high impedance usually imparts an insignificant load on the test circuit, but at high frequencies, the input capacitance may affect accuracy.

Grounding the probe is not always necessary, but it may improve waveform fidelity in certain cases. Avoid creating ground loops that could add noise to signals. Try different grounding configurations to determine the best performance.

Safety & Warnings

The AP034 Active Differential Probe manual includes the following safety warnings and precautions:

1. The probe’s input circuits have components to protect against electrostatic discharge (ESD), but it should still be handled carefully to avoid damage.
2. Precautions should be taken to prevent potential instrument damage due to ESD when using the probe.
3. Do not attempt to insert connectors or wire larger than 0.036 inches (0.91 mm) in diameter into the input connectors to avoid damage.
4. Avoid rotating square pins after they are inserted into the input connectors to prevent damage.
5. Do not use the attenuator encoding receptacle to ground the probe, as it will not provide adequate grounding and may result in incorrect scale factor indication.
6. Connecting the probe ground to a circuit that is referenced to earth ground can create a ground loop and may add noise to low-amplitude signals.
