NI PXI-6711 4-Channel 12-bit High-Speed Analog Output Module

The NI PXI-6711 is a 4-channel, 12-bit analog output module for PXI systems delivering simultaneous multichannel waveform generation and deterministic control. Each channel supports up to 1 MS/s update rates with ±10 V or ±EXT REF output ranges, making it suitable for stimulus-response testing, power supply control, sensor simulation, and complex waveform synthesis. The module features double-buffered, multiplying DACs with ±0.3 LSB typical INL and includes 8 digital I/O lines (5 V TTL/CMOS), 2 counter/timers (24-bit, 20 MHz maximum), and comprehensive trigger/synchronization support via PXI Trigger Bus and external clocking.
