Applications

  • Communications (Gigabit Ethernet, IEEE-1394, Fibre Channel)
  • Semiconductor Characterization (RAMBUS)
  • Disk Drive Read Channel Design
  • Communication Pulse Shape Compliance
  • Jitter, Crosstalk, and BERT Measurements
  • Location of Ground Bounce

The P6246, P6247, and P6248 Differential Probes

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 manual 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 problems associated with high-speed logic. They can also be used for pulse shape or crosstalk compliance testing of high-speed communication signals.
