Cal Test Electronics CT3688A
Active Differential Probe Kit 200MHz, 10x Small Signal +/-20V
Order #: CT3688A
Mfg #: CT3688A
Product Highlights
Differential probes allow safe, accurate measurement between two voltage points where neither point is referenced to ground. The CT3688A off ers a 200 MHz bandwidth and can test up to ±60 V (DC + AC peak). Compatible with oscilloscopes from all major manufacturers, the probe can be battery operated or powered directly from an oscilloscope using the included USB cable.
- Meets IEC 61010-031 safety standard
- Small compact size
- Up to ±20 V differential
- High accuracy ±1%
- 200 MHz bandwidth (-3dB)
- Excellent CMRR
- Kit comes in foam-lined plastic case and contains:
- Differential probe
- (2) Sprung hook probes, 1000 V, CAT III, 20 A (black & red)
- (2) Alligator clips, 300 V, CAT II (black & red)
