This acquisition system utilizes Tektronix' SiGe probe ASIC. The P7380-SMA is designed for measuring differential signals in a 50 Ohm signaling environment, providing the ability to convert from a dual-SMA signal path to a single oscilloscope input channel. Many of the new high-speed serial data standards employ differential signaling on multiple lanes. The P7380-SMA provides the ability to measure a high-speed differential signal on each channel of a multiple channel oscilloscope. The P7380-SMA also provides a common mode DC voltage input to the termination network. The termination voltage can be supplied either externally or internally. In addition, there is an automated mode where the termination voltage is supplied automatically to match the common mode voltage of the input signal.
