Switchable Attenuation 1:1 / 1:10 Gain error less than 1% Operating common mode voltage range: ±120V Maximum input voltage: ±500V Powered from 9V battery or external supply Compatible with all standard oscilloscopes
The EA132 Differential Probe is an auxiliary device for any standard oscilloscope. It can be connected to any measuring channel and it is powered directly from a 9V battery or from a wall adapter (9-16V DC, 1200mW). A European wall adapter is included. You can order a U.S. power supply from our options below.
It has a BNC cable for connecting to your measuring device. The input resistance of your device should be higher than 20 kΩ, and its input capacity should be lower than 30 pF. When an oscilloscope is the measuring device, switch the input to the 1 MΩ mode.
This probe's input terminals are 4mm protected banana plugs.
A unique feature of the EA132 probe is the exceptionally high operating common mode voltage together with a 1:1 attenuation. Thanks to these features, it is possible to measure differential voltages of tens of millivolts amplitude while common mode voltage is up to 120V.
The box measures 175 × 61 × 23 mm.
