Teledyne LeCroy AP Series AP033 Oscilloscope Probe, Active, Differential Type, 500MHz, 1:1, 10:1, ProBus Connector

The Teledyne LeCroy Fully Integrated: With the ProBus™ interface, the AP033 becomes an integral part of the oscilloscope. The probe sensitivity and offset can be controlled from the oscilloscope front panel, the probe front panel, or by using remote control commands (GPIB or RS-232). Sensitivity, offset, input capacitance, and common mode voltage range are displayed on the oscilloscope screen. When used with a LeCroy digital oscilloscope, no external power supply is required.

Wide Dynamic Range: The AP033 provides a range of sensitivities from x10 gain to ÷10 attenuation (even ÷100 with plug-on attenuator) for diverse signals. The sensitivity can be adjusted continuously from 200 μV/div to 1 V/div, when used with a LeCroy oscilloscope.

The input capacitance is just 2 pF/side (1 pF differential) whenever the ÷10 ATTENUATION is selected. Deflection factors of 2 mV/div to 1 V/div can be obtained with only 2 pF/side input capacitance and ±50 V CMVR.

At high sensitivities, the x10 GAIN and the ÷1 ATTENUATION are selected. This produces 4 nV/√Hz input noise, ±5 V of common mode voltage range (CMVR), and ±400 mV of DC differential offset. At lower sensitivities, the x1 GAIN and ÷10 ATTENUATION are selected, resulting in ±50 V CMVR and ±4 V of differential offset.

The input capacitance is just 2 pF/side (1 pF differential) whenever the ÷10 ATTENUATION is selected. Deflection factors of 2 mV/div to 1 V/div can be obtained with only 2pF/side input capacitance and ±50 V CMVR
DC CMRR is greater than 10,000:1 (80 dB) in both ATTENUATION settings
OFFSET up/down buttons allow OFFSET control from the probe amplifier body. Momentarily holding both buttons will zero the OFFSET
A supplied AC coupling capacitor head (0.1 μF) allows operation with large common mode or differential DC inputs

The input attenuator automatically changes from ÷1 to ÷10 when too much common mode signal is sensed. This and a fast input protection circuit also serve to protect the input from potentially damaging signals. When the probe is removed from the oscilloscope or the power is turned off, the ÷10 ATTENUATION is automatically invoked, leaving the inputs protected when not in use
