Agilent U2781A USB Modular Instrument Chassis

Agilent U2781A USB modular instrument chassis is a 4 U high chassis with six USB module slots. This portable chassis provides housing for up to six Agilent U2300A Series USB modular multifunction data acquisition (DAQ) devices. This further expands Agilent’s range in PC-based data acquisition solution, especially in the R&D, design validation and manufacturing fields as DAQ is widely used by engineers in those areas.

The U2781A modular chassis is an AC powered device and equipped with an external 10 MHz reference clock and external trigger in and trigger out functions.

Key Features and Specifications

• 6 USB module slots
• High-speed USB 2.0 (480 Mbit/s)
• Hot-swappable and auto-detectable characteristic minimizes startup time/effort
• Allows expansion up to 384 channels
• Mountable to rack with an optional rackmount kit
• Simultaneous synchronization between modules
• SSI/Star trigger bus synchronization between external trigger source and modules

Easy to use

The USB 2.0 high speed interface enables the device to have a plug-and-play and hot swappable connectivity.

High density data acquisition

Allows an expansion of up to 384 channels when slotted with the U2300A Series DAQ devices, providing a high density data acquisition solution.

Triggering using star trigger bus

The U2781A USB modular instrument chassis comes with star trigger bus, which offers precise synchronization between USB modules and the external trigger signal. The star trigger bus comprises of dedicated trigger lines between the external trigger input and slotted USB modules. Users can also achieve precise triggering between each USB modules via the synchronized routing of the star trigger.
