Product Overview

Product Highlights

Differential probes allow safe, accurate measurement between two voltage points where neither point is referenced to ground. The CT3688A off ers a 200 MHz bandwidth and can test up to ±60 V (DC + AC peak). Compatible with oscilloscopes from all major manufacturers, the probe can be battery operated or powered directly from an oscilloscope using the included USB cable.

Meets IEC 61010-031 safety standard
Small compact size
Up to ±20 V differential
High accuracy ±1%
200 MHz bandwidth (-3dB)
Excellent CMRR
Kit comes in foam-lined plastic case and contains:
