The Keysight 44725A is a 16-channel general-purpose switch module engineered as a terminal block for direct integration into Keysight data acquisition systems. It switches voltage, current, and power using low-noise, break-before-make SPDT Form C relays, with each channel individually programmable and state-retentive. The module delivers excellent between-channel isolation and supports signal frequencies to 100 kHz, making it ideal for precision measurement and control applications requiring reliable signal wire termination and switching.
