More information

Differential signaling used in high speed serial standards requires very accurate characterization. The industry-leading bandwidth and signal fidelity found in a Tektronix low voltage differential oscilloscope probe ensures that you see every possible detail. Tektronix offers TriMode™ architecture which streamlines measurement acquisition by enabling you to make differential, single-ended, and common mode measurements with a single connection!



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.

  • 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



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.
