Tektronix DPO7254 Digital Phosphor Oscilloscope

Tektronix DPO7254 Digital Phosphor is the new generation of real-time digital phosphor oscilloscopes and are the industry’s best solution to the challenging signal integrity issues faced by designers verifying, characterizing, debugging, and testing sophisticated electronic designs.

The DPO7254 oscilloscope includes as a standard feature a series of user-selectable bandwidth limit filters. These filters preserve the instrument’s bandwidth roll-off characteristics, flatness, and phase linearity within the new frequency range, thereby reducing the effects of out-of-band noise on measurements. Now, designers can purchase one instrument for their highest bandwidth needs and easily optimize it to handle lower-frequency measurements as well.

Tektronix DPO7254 Digital Phosphor Oscilloscope provides turnkey testing & characterization solution for 10GBASE-T measurements as outlined in IEEE 802.3 Section 55, and for 5GBASE-T and 2.5GBASE-T as outlined in IEEE P802.3bz, Section 16; NBASE-T Spec Draft. The industry’s solution to the challenging signal integrity issues faced by designers verifying, characterizing, debugging, and testing sophisticated electronic designs.
