U2781A chassis
On the bench: Integration made easy
U2781A USB modular product chassis
The U2781A is a six-slot chassis for Agilent USB modular instruments and data acquisition devices. It offers the
convenience of one AC-power connection and a single USB link. Modules are hot-swappable and the auto-detection
feature reduces setup time and effort. This 4U-high chassis also provides simultaneous synchronization between modules
and enables SSI/star-trigger bus synchronization with an external trigger source.
Six USB module slots
System Synchronous Interface (SSI)
Star trigger and trigger-in/trigger-out signals
Internal and external 10 MHz reference clock
SCPI and IVI-COM compatibility
The U2781A modular chassis allows expansion up to 384 channels when slotted with the U2300A Series DAQ devices,
providing a high-density data acquisition solution. The optional rackmount kit simplifies integration into a test system.
The chassis’ master/slave triggering capabilities also enable synchronization among various modules. This is possible even
across modules with different functions (except for the switch matrix).
Its compact size saves space on the bench or in a rack. Hi-Speed USB 2.0 compatibility makes connection to a PC
quick and easy.
