Tektronix announced the P7313SMA differential probe. With 13 GHz bandwidth the SMA probe is dedicated for serial bus validation and compliance testing of high-speed standards including HDMI 1.3. SMA probes provide the capability for customers to connect to two SMA connectors on their device under test and bring those two signals into a differential probe that converts the two complementary signals into one single-ended signal.

The probe is designed for measuring differential signals in a 50Ω signaling environment, providing the ability to convert from a differential SMA signal path to a single oscilloscope input channel. The P7313SMA provides a common mode DC voltage input to the termination network. The termination voltage can be supplied either externally by the user or internally by the oscilloscope. There is also an automatic mode that senses the common mode voltage of the input signal and automatically sets the termination voltage to match.
