The ADQ412 is a 2/4 (Dual/Quad) channel flexible digitizer that offers an outstanding combination of high bandwidth and dynamic range, which enables demanding measurements such as RF/IF sampling of very wide band signals. The high sampling rate is enabled by SP Devices' proprietary interleaving technology ADX.

The AFE of ADQ412 is AC-coupled and optimized for spectral purity over a wide bandwidth. The lower cut-off frequency is as low as 6 kHz and the bandwidth is set by the mode of operation. See the product information table to the right for more information.​

The digitizer connects to the host via a high-speed USB 3.0 cable for easy to use standalone operation. Compact PCI Express / PXI Express or MTCA.4 µTCA interface is available for systems integration as a modular instrument. A PCIe version for integration into a PC is also available. All interface types allows for streaming of data at high transfer rates.​​​​
