PicoBNC+ 1400V Differential Probe Kit for Automotive Oscilloscopes (PQ345) includes the TA511


1400 V differential probe kit brings all the PicoBNC+® benefits to high-voltage measurements

SKU: PQ345 Categories: , Tag:


The PQ345 1400 V differential probe kit brings all the PicoBNC+® benefits to high-voltage measurements, including probe recognition and elimination of manual switching and batteries. Technicians can use up to three of these probes simultaneously with the PicoScope 4425A Automotive scope, while still meeting all safety requirements.

The heart of the kit, the TA511 probe is equally effective at handling high-voltage signals for EV and Hybrid systems, all the way down to low-voltage differential signals such as 5 V communications, for example, CAN.
