– Compatibility & Integration
The module integrates into VXIbus systems as a single-slot C-size instrument. It directly supports LVDTs and RVDTs across the 360 Hz to 20 kHz excitation frequency range. External control signals (±10 Vdc or ±5 Vdc differential) enable synchronization with external measurement systems. CIIL programming provides command-level control, accepting numeric and string data formats for flexible stimulus configuration.
