Probes
The P6248, P6247, and P6246 e nable users to make time-domain or
ncy-domain measure ments on high-bandwidth signals commonly
freque
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
probing of surface-mount devices while maintaining high CMRR.
manual
The P6246, P6247, and P6248 are ideal for design verification of disk
ead, channel electronics, and timing analysis for tro ubleshooting
drive r
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.
