Product Overview
CT3687 is a high-voltage active differential probe designed for safe, accurate floating measurements up to ±1,400V. With a wide 100MHz bandwidth, switchable attenuation (100x / 1000x), and ±1% accuracy, it’s ideal for power electronics, motor drives, and high-voltage R&D applications. Compatible with any oscilloscope with 1Mohm input impedance, the CT3687 operates on 4AA batteries (included) or optional AC adapter (CT3723) or USB power lead (CT4122). It comes complete with hook probes and a digital user manual for immediate use. Applications include switching power supply development, power inverter and converter testing, motor drive system measurements and precision high-voltage differential diagnostics.
- ±140V at 100x, ±1,400V at 1000x differential input
- 100MHz bandwidth (-3dB), 3.5ns rise time
- High CMRR of -80dB at 60Hz
- Power and over-range indicators
- Offset (typical): ±5mV (adjustable), noise (typical): 0.9mVrms
- IEC 61010-031 CAT I safety rating
