The P6248, P6247 and P6246 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 man-
ual probing of surface mount devices while
maintaining high CMRR.
The P6246, P6247 and P6248 are ideal
for design verification of disk drive read,
channel electronics and timing analysis
for troubleshooting ground bounce prob-
lems associated with high-speed logic.
They can also be used for pulse shape
or cross talk compliance testing of high-
speed communication signals.
