P6248

The P6248, P6247, and P6246 Differential Probes enable users to make

time-domain or frequency-domain measurements on high-bandwidth signals

commonly found in disk drive, digital IC design (RAMBUS), and

communication applications (Gigabit Ethernet, IEEE-1394 Firewire, and

Fibre Channel). The P6248 includes accessories that allow RAMBUS via

probing and IEEE-1394 interconnect access. The small probe head

geometry and assorted probe tip accessories allow these probes to easily

accommodate manual probing of surface-mount devices while maintaining

high CMRR.
