Astronics / EADS / Talon Instruments SR214A Variable Voltage Stimulus/ Response Module

The Astronics/EADS/Talon Instruments SR214A is a variable voltage stimulus/response module engineered for signal generation and measurement within the SR192A Digital Test System. This 16-channel module delivers flexible voltage stimulus and response capabilities for automated test equipment and laboratory applications. It integrates with other SR192A module types

LVDS, TTL, and RS-485 - enabling custom digital test configurations across 8 to 192 channels.

Compatibility & Integration The SR214A operates within the SR192A Digital Test System VXI module architecture. Multiple SR214A modules can be intermixed with LVDS, TTL, and RS-485 modules. The parent SR192A system scales from 8 to 192 channels per module, with support for master/slave linking and up to 1152 channels in a single 13-slot chassis. Trigger inputs accept VXI TTL, VXI ECL, front panel auxiliary, or channel-level triggers with offset-capable sync outputs.
