Keysight/Agilent 34980A Multifunction Switch/Measure Unit
The Keysight/Agilent 34980A Multifunction Switch/Measure Unit is a mainframe of eight slots for medium to high-density switching and measurement applications in design verification, automated test systems, and data acquisition. The economical solution accommodates up to 19 plug-in modules such as low-frequency multiplexers, RF/microwave switches up to 20 GHz, digital I/O, D/A converters, and counter/totalizer modules for flexible system configuration. A 6½-digit internal DMM option enhances measurement capability without consuming module slots, with 11 types of inputs supported like DC/AC voltage, temperature (thermocouples, RTDs, thermistors), 2-/4-wire resistance, frequency, and current.
The 34980A handles as many as 560 2-wire multiplexer channels or 1024 matrix crosspoints in a single mainframe, with expandability for such applications as battery testing, environmental testing, product characterization, and thermal profiling. Low-frequency modules include armature and reed relays with up to ±300 V voltage ratings and up to 1000 channels per second switching rates. RF/microwave modules provide insertion losses as low as 0.42 dB, frequencies up to 20 GHz, and SPDT switching or attenuator control configurations. System control modules are equipped with Digital I/O channels that have 64 bits of resolution as well as isolated analog outputs and programmable clock signals.
The 34980A boasts a simple interface, using standard 50- or 78-pin DSUB cables and accessories. LabVIEW, IVI, and SCPI are some of the software environments compatible with the device. Some of the standout features of the switch/measure unit include remote programming, switch sequencing, and real-time monitoring. These features are offered in a browser-based graphical interface using Java-enabled devices, and they support relay state checking, error logging, and firmware download functionality.
Manufacturing and Research + Development applications are ideal for the 34980A unit, which offers flexible hot-swappable modules that can help lower system costs by up to 40%. Compact in design and with a mix-and-match modular architecture, scalability is guaranteed for future test needs, ranging from signal switching in RF systems to high-current switching for actuator control. Applications range from aerospace and automotive to consumer electronics and industrial quality control, with an emphasis on precision, flexibility, and simplicity of deployment in automated test applications.
