Arbitrary waveform generator targets component testing, quantum research, spectroscopy apps

A new arbitrary waveform generator (AWG) called the HDAWG is a high-density multi-channel
instrument featuring high channel density and low trigger latency (<50 nsec). Both four and eight-channel models offer 16 bits of vertical resolution at a sampling rate of up to 2.4 GSa/sec and a signal bandwidth of 750 MHz. The maximum output amplitude is ±5 V. Software included with the instrument called LabOne is designed to enable efficient workflows. It has browser-based instrument control and APIs for widely used software environments. The LabOne sequencer combines waveform and sequence definition in a single editor and enables the use of a parameterized control sequence and internal oscillators. It reduces the need for sample-based waveform definition from third-party software and so reduces waveform transfer times. Additionally, a C-like sequence language makes it easy to define branching conditions so the user will find it much easier to stay on top of the signal generation complexity required for demanding multi-channel applications.

LabOne also contains multi-device synchronization supporting a user-friendly way to scale up to 64 channels on eight automatically synchronized instruments at the picosecond level. Waveforms are defined in a single editor, then compiled and distributed across multiple instruments.

The AWG targets multi-channel applications demanding high signal fidelity. In quantum computing, for example, many channels must run with full synchronicity but must be able to quickly break out new branch sequences based on measurement results. Also, pairing two channels for I/Q mixing is naturally supported for implementations where frequency up-conversion is needed. NMR and other spectroscopy applications benefit from the advanced modulation schemes based on internal oscillator, variable sampling rates, and parametric sweeping. Nested sequencing, waveform iteration, and dynamic sequencing with DIO control are candidates for high-throughput device testing. Multiplying or adding the AWG signal with a function generator signal extends the possibilities and helps simplify and speed daily measurement routines.

The HDAWG was developed by Zurich Instruments in Switzerland. Price of the HDAWG starts at $5,500 per channel.
