Active Catalog70 MHz High Voltage Differential Probe
Differential Probe Kit, 70MHz 100x/1000x HV w/Probes & PS
$1,152.001 Year Warranty
Overview
The CT3681 is a high-voltage active differential probe designed for safe, accurate floating measurements up to ±7,000 V. With a wide 70 MHz bandwidth, switchable attenuation (100x / 1000x), and ±2% accuracy, it’s ideal for power electronics, motor drives, and high-voltage R&D applications.
Compatible with any oscilloscope with 1 MΩ input impedance, the CT3681 operates on 4 AA batteries (included) or optional AC adapter (CT3723) or USB power lead (CT4122). It comes complete with hook probes and a user manual for immediate use.
Key Features:
- ±700 V @ 100x, ±7,000 V @ 1000x differential input
- 70 MHz bandwidth (-3 dB), 5 ns rise time
- Switchable 100x / 1000x attenuation
- ±2% accuracy, high CMRR: -80 dB @ 50 Hz
