Precision Voltage Generators

QDAC-II is a high-precision, 25-bit resolution, ultra-low-noise DAC with 24 voltage channel generators with a 1 MS/s sample rate and a step size of 0.12 μ. Each of the 24 channels has five voltage generators working in parallel: One for DC, a sine generator, a triangle generator, a square wave generator, and an arbitrary waveform generator.

Fast Tune-Up and Operation Point Control

Performs fast multi-dimensional gate voltage sweeps using a 300 kHz output filter. Once at your operation point, QDAC-II is switchable to an ultra-low noise DC voltage with a 10 Hz output filter and 25-bit resolution, with minimal transients.

Complete and Scalable Solution

QDAC-II offers a high-performance and versatile solution with an endless number of applications. Multiple OPX+ and QDAC units can be stacked and synchronized to operate as one advanced quantum control system.
