Product Description

Precision differential probes allow for safe, accurate measurements between two voltage points where neither point is referenced to ground and high accuracy is required.

Model CT3688 features a fixed 10x attenuation setting, 200 MHz bandwidth and ±20 V maximum differential.

Differential probes allow safe, accurate measurement between two voltage points where neither point is referenced to ground. The CT3688 offers 200 MHz bandwidth and can test up to ±60 V (DC + AC peak). Compatible with oscilloscopes from all major manufacturers, the probe is powered by the included 9 VDC adapter.

  • Up to ±20 V differential
  • 200 MHz bandwidth (-3 dB)
  • High accuracy ±1%
  • Safety certified
  • Small size
  • Good CMRR
  • Includes: Spring loaded hook probes, manual, 9 VDC adapter (CT3723)

Applications include:

  • Precise power semiconductor device measurements
  • Switching power supply design
  • Precise measurement of power converters
  • Precise measurement of motor drives
