Keysight (Agilent) 44473A 4x4 Matrix Switch Module

The Agilent 44473A Matrix Switch provides a 4 x 4 matrix of 2-wire switches. Each node (crosspoint) in the matrix contains a latching relay that connects a row to a column. Both Hi (H) and Lo (L) lines are switched. More than one switch can be closed at a time, allowing any combination of rows and columns to be connected. This matrix switch offers highly flexible switching for testing devices over a frequency range of dc to 100 kHz. Multiple 44473A modules may be connected together to form a larger matrices. The 44473A can also be used in conjunction with other modules (such as the 44470A 10-Channel MUX) to provide a wide variety of switching combinations. When wiring between multiple modules, keep wire length as short as possible to minimize noise and signal degradation.

Channel Bandwidth
Channel Bandwidth is the bandwidth over which power is measured. This is usually the bandwidth in which almost all of the power of a signal is contained.

Jitter in technical terms is the deviation in or displacement of some aspect of the pulses in a high-frequency digital signal. Jitter is the time variation of a periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals. Jitter is a significant, and usually undesired, factor in the design of almost all communications links (e.g., USB, PCI-e, SATA, OC-48). In clock recovery applications it is called timing jitter.

Overshoot is the distortion that follows a major transition; the difference between the peak power point and the pulse-top amplitude computed as a percentage of the pulse-top amplitude.

Rise Time
Rise time refers to the time required for a signal to change from a specified low value to a specified high value, usually 10 and 90 percent of pulse-top amplitude (vertical display is linear power).
