The Keysight/Agilent/HP 44725A is a 16-channel general-purpose switch module that expands signal routing and switching capabilities in automated test systems. Built around SPDT Form C relays with break-before-make action and low noise characteristics, it provides straightforward, individual channel programming with non-volatile memory retention. The module directly switches voltage, current, and power signals up to 100 kHz with excellent between-channel isolation.
Technical Specifications
• Channels: 16
• Switch Type: SPDT Form C relays (break-before-make, low noise)
• Maximum Voltage: 30 VDC, 42 V peak AC
• Maximum Signal Frequency: 100 kHz
• Programming: Individual channel control with retained memory state
• Switching Function: Voltage, current, and power
• Shipping Weight: 15 lbs
– Key Features
• Break-before-make relay action eliminates signal crossover and crosstalk during transitions. Between-channel isolation enables clean signal routing in multi-channel measurement configurations. Each channel operates independently under software control. Memory persistence eliminates the need for reprogramming after power cycles. Terminal block interface supports standard wiring practices.
– Typical Applications
• Multi-signal routing in automated test environments
• Power supply and load switching verification
• Low-frequency analog signal multiplexing
• General-purpose switching in data acquisition systems
– Compatibility & Integration
Designed for integration with the Agilent 3852A Data Acquisition and Control Unit. Configuration and programming documentation is available (Agilent/HP Part Number 44725-90002).
