The National Instruments PXI-6713 is an 8-channel analog output module for PXI and CompactPCI systems, delivering 12-bit resolution at up to 1 MS/s per channel. Built for stimulus-response testing, power supply control, deterministic signal generation, and sensor simulation, the module generates complex waveforms including square, sine, and sawtooth signals with simultaneous multichannel updates. Output voltage ranges span ±10 V and ±EXT REF, with post-calibration accuracy of ±0.3 LSB typical (±0.5 LSB maximum INL) and ±0.3 LSB typical DNL.
