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.

P6248, P6247, and P6246 Differential Probes
The P6248, P6247, and P6246 Differential Probes are ideal for design
verification of disk drive read, channel electronics, and timing analysis for
troubleshooting ground-bounce problems associated with high-speed logic.
They can also be used for pulse shape or crosstalk compliance testing of
high-speed communication signals.
