The DSA8300 Series Sampling Oscilloscope, when configured with one or more electrical sampling modules, provides complete test solutions for multi-channel, high-bandwidth electrical applications. This highly configurable solution is well suited for debugging, characterizing and analyzing components, modules and systems with signaling rates at 10, 40 and even 100 Gb/s. The 80E00 family of electrical sampling modules provide a wide variety of capabilities, allowing the user to configure a test solution specifically adapted to their application.

The 80E04 is a dual-channel Time Domain Reflectometry (TDR) sampling module, providing up to 23 ps incident and 28 ps reflected rise time. Each channel of this module can generate a fast step for use in TDR mode and the acquisition portion of the sampling module monitors the incident step and any reflected energy. The polarity of each channel’s step can be selected independently. This allows for differential or common mode TDR or S-parameter testing of two coupled lines, in addition to the independent testing of isolated lines. The independent step generation for each channel allows true differential measurements, which ensures measurement accuracy for differential devices.
