ChronoLogic’s Legato series of Universal Timing Devices (UTD) are part of the “USB-inSync™” product family. The Legato UTD provides a means to precisely control external equipment, trigger events, and provide synchronous clocks to users’ existing laboratory equipment.

The Legato UTD can also synchronously provide time stamped trigger events to other ChronoLogic USB-inSync™ products, such as the “USB DAQ-2500X”, and enable their direct integration with existing test and measurement equipment enabling a significant array of test and measurement “applications”.
These simple and affordable timing devices provide users with a unique range of scalable, distributed timing solutions combined with the ease and efficiency of USB based PC control. Legato UTD’s are available with either BNC connectors or RJ45 connectors when you require differential signaling using inexpensive Cat5 or Cat6 cable.

The Legato UTD can be used to generate a sequence of events at a predefined time. This means that software configurable, synchronous control sequences or bit patterns can be created and distributed across multiple Legato devices in a test setup. The Legato UTD can also be used to synchronize a device under test with external test equipment and a DAQ module, whether it is a ChronoLogic USB DAQ Module, or legacy DAQ.

The Legato UTD can also be used to distribute externally referenced absolute time signatures (such as GPS time, IRIG time codes or IEEE 1588 time) around a local environment. All Legato devices contain I/O cable propagation delay compensation for phase accurate compensation of signals right up to your device under test. Multiple Legato devices can be combined with signal conditioning units (“ChronoLogic Sonda”) to create a virtual/synthetic instrument covering distances of several hundred metres. Beyond practical cabling distances they can also be combined with our GPS enabled “Master Timing Hubs” to provide worldwide synchronization. Examples can be found in our “Application Center”.

Software

To provide flexibility and easy control, the Legato UTD is supplied with ChronoLogic’s Control Center software platform, complete with a simple to use Graphical User Interface (GUI). For advanced users, access to extended low-level device functionality is available through our COM Server. This enables interfacing through Windows based software application including MS Office, Visual Studio and National Instruments LabVIEW™. Additional LabVIEW™ device drivers are available so that USB-inSync™ devices can be quickly implemented within an existing test environment.
