Formerly known as Zmod DAC.

The Digilent Zmod AWG, is an open-source hardware SYZYGY™ 1) compatible pod containing a dual-channel DAC and the associated front end. The Zmod AWG is intended to be used with any SYZYGY™ compatible carrier board having the required capabilities.

The analog outputs can be connected to a circuit using SMA cables. Driven by the SYZYGY™ carrier, the Zmod AWG can generate two simultaneous signals (50Ω, ±5V, single-ended, 14-bit, 100MS/s, 40MHz+ bandwidth).

The Zmod AWG was designed to be a piece in a modular, HW and SW open-source ecosystem. Combined with a SYZYGY™ carrier, other SYZYGY™ compatible pods, Zmod AWG can be used for a variety of applications: data acquisition systems, closed loop controllers, etc.

Getting Started

As of the time of writing, two different versions of the supporting materials for the Zmod AWG exist.

Latest Release

The Zmod AWG 1411 Controller is the second release of the low-level controller IP. As of the time of writing, this IP is not compatible with the AXI Adapter or Zmod Library.

For a hardware-only project demonstrating its use, see the Eclypse Z7 Low-Level Low-Pass Filter Demo.

Initial Release

The initial release of demos for the Eclypse and Zmod AWG uses the Zmod Library to control the Zmod AWG through the Zmod DAC 1411 AXI Adapter and Zmod DAC 1411 Low Level Controller IPs.

For information on getting started with the Zmod Library, and for using these IPs, check Section 3 of the Zmod Base Library User Guide. These IPs and the Zmod Library are also used in demos for the USB104 A7, which you can find through its Resource Center.


Compatible Digilent Host Boards


These tutorials step through the process of creating a hardware platform that supports the Zmod AWG 1411. Prebuilt images for the Eclypse Z7 are available on the Digilent GitHub. The process of working with these prebuilt images is documented in Section 3 of the Zmod Base Library User Guide.
