The CT4066 differential probe allows safe, accurate measurement between two voltage points where neither point is referenced to ground. The probe offers both a 25 MHz bandwidth for the 50x and 200x attenuation settings and a 15 MHz bandwidth for the 20x attenuation setting. Compatible with oscilloscopes from all major manufacturers, the probe is exclusively powered by the included 9 V power adapter.

Features:

  • Meets IEC 61010-031 safety standard
  • Selectable attenuation settings of 10x/100x
  • 25 MHz bandwidth (at 50x/200x attenuation settings)
  • 15 MHz bandwidth (at 20x attenuation setting)
  • Up to ±700 V differential
  • High accuracy (±2%)
  • Power and over range indicator LEDs

Comes with:

  • (2) Pincer Clips, black & red
  • (2) Alligator Clips, black & red
  • (2) Sheathed 4 mm banana plug test leads, silicone jacketed, black & red
  • Insulated BNC cable, 100 cm
  • 9 V Power adapter included (CT3957)
