Model STG-16 - PRODUCT DISCONTINUED
The Voss Scientific Inc. Model STG-16 Synchronized Trigger Generator is designed to produce level transitions on the 16 output channels at specific absolute times or in response to an external trigger. In addition, the unit can record the absolute time of level transitions on the external trigger input. The device determines the absolute time from an input IRIG signal or from an integrated GPS receiver.
Multiple STG-16 devices coupled to independent IRIG sources can be used to simultaneously trigger devices at widely separated physical locations. Multiple units can also be used in triangulation applications, such as localization of lightning or similar phenomena.

The STG-16 features an RS-232 and Ethernet interface. The unit can be controlled through these interfaces via a stand-alone software application available on Linux and Windows platforms, or with Voss Scientific Inc.’s DAAAC software. A C-language interface library for Linux or MS Windows is also available.
The STG-16 can persistently (remains when powered down) store complex periodic or single shot event sequences of arbitrary length. In addition multiple sequences can be run simultaneously enabling for example, a complex periodic sequence to run on one set of channels while the other channels can be used for prerecorded sequences triggered through software at specific times.
