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.
## Technical Specifications
• **Channels:** 16 per module; configurable in 8-channel increments
• **Data Rate:** Up to 25 MHz; 50 MHz when multiplexed
• **Timing Rate:** Up to 50 MHz
• **Voltage Range:** -5V to +7V
• **Source/Sink Current:** 50 mA
• **Memory Architecture:** 5 types (Stimulus, Tristate, Record, Expect, Mask)
• **Memory per Channel:** 128 Kbits; 256 Kbits when multiplexed
• **Edge Placement Resolution:** 5 ns
• **Channel-to-Channel Skew:** 5 ns
## Key Features
• Variable voltage stimulus and response in a single module
• Single-ended or double-ended logic I/O configuration
• High-speed data sequencer supporting UUT handshaking, pattern control, looping, and conditional testing
• 5 ns edge placement resolution for precise timing control
• Supports LSRTAP file data import
## Typical Applications
• Mixed-signal and digital device testing
• Automated test equipment (ATE) environments
• Complex pattern-based signal generation and verification
• Flexible voltage stimulus scenarios requiring -5V to +7V stimulus levels
## 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.
