Cal Test Electronics CT3684 50 MHz Differential Probe


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 CT3684 features a fixed 10x attenuation setting, 50 MHz bandwidth and ±70 V maximum differential.

Compatible with oscilloscopes from all major manufacturers, the probe can be battery operated or powered by a universal power adapter (not included).

  • Small size
  • Up to ±70 V  differential
  • High accuracy ±1%
  • 50 MHz bandwidth (-3 dB)
  • Good CMRR
  • Reference SI-50
  • Optional power adapter, 9 V 500 mA, CT3723
  • Kit comes in foam-lined case and contains:
    • Differential probe
    • (2) Hook probes, black & red
    • User manual
