Astronics / EADS / Talon Instruments SR192 Digital Test Module

The Astronics/EADS/Talon Instruments SR192 is a VXI-based digital stimulus and response test module engineered for high-channel-count digital applications. This dual-slot C-size VXI module accommodates up to twelve I/O modules, delivering 96 to 192 digital I/O channels per unit with synchronization capability reaching 1152 channels across multiple modules. The SR192 supports TTL, ECL, RS485/422, and variable voltage logic (+/−15V or +5/−2V), configurable as single-ended or double-ended outputs with 50 mA source/sink current per channel. ## Technical Specifications • Digital I/O Channels: 96 to 192 per module; up to 1152 channels with multiple synchronized modules • Timing Rate: 50 MHz maximum • Data Rate: 25 MHz; 50 MHz multiplexed • Memory Depth: 128 Kbits per channel (256 Kbits multiplexed) • Edge Placement Resolution: 5 ns • Channel-to-Channel Skew: 5 ns • Source/Sink Current: 50 mA per channel • Logic Options: TTL, ECL, RS485/422, variable +/−15V, +5/−2V • Memory Architectures: Stimulus, Tristate, Record, Expect, Mask • Data Formats: Hold, RTZ, RT0, RTC • Test Sequence Memory: 128 Kbits • Timing & Control Channels: 20 channels • Configuration: Single-ended or double-ended logic ## Key Features • Modular front-end design supports SR115 bi-directional 16-channel modules, SR112/SR122 8-channel RS485 differential modules, SR125A, and SR214A variable voltage modules • SR101/SR101A Timing Set modules provide sequence control, UUT handshaking, pattern data management, and conditional testing with up to 128 K test sequence memory • Conditional and unconditional jump sequences with go-sub test capability • Parallel and serial bus emulation support • Optional SR210 Accessory Module (100 Hz to 50 MHz programmable clock) and SR110 DAC Module • SCPI-compatible command interface matching Talon BE-64 protocol ## Typical Applications Digital functional testing, bus emulation, parallel and serial protocol validation, multi-channel stimulus/response characterization. ## Compatibility & Integration VXI ecosystem; controlled by SR101/SR101A timing modules; integrates with SR110 DAC and EADS SR107 PIO accessory modules; SCPI message-based programming interface.
