The NSI-MI Vector Measurement Controller (VMC) is a master timing controller for complex electronic measurement and data acquisition. It can be used for fast on-the-fly electronic testing, precisely coordinated with mechanical motion or other controlled or monitored test attributes. As an enhancement to NSI-MI’s Vector Field AnalyzerTM, the VMC provides comprehensive support of electronically steerable and digital antennas for automated testing. A complete set of selectable trigger and data inputs and outputs gives the VMC the ability to control practically any device or instrument with precise timing resolution.
- Fast, precise acquisition controller for complex coordinated measurement tasks
- Compatible with legacy and third-party instruments
- Integrated RF multiplexer control functions
- Comprehensive AESA control interface
- Digital antenna data interface
- 10 ns timing resolution
(A) Ten programmable BNC I/O: For triggers and responses; tri-color LEDs show input/output signal logic.
(B) Universal AC input: 100 to 240 V AC
(C) Trigger Bus: Simple timing interface with other NSI-MI instruments
(D) Standard TTL interface: Beam steering / AESA control, triggering, GBCR
(E) Differential TTL interface: Beam steering / AESA control, triggering, GBCR
(F) Dual 8-bit MUX: RF multiplexer, switch, or other control via parallel TTL
(G) Console, Host, SD card: Behind lockable service panel; removing the SD card clears instrument memory.
(H) Dual Gigabit Ethernet: Control and AUT data handling
