Overview
Overview
The SDR14TX is a dual-channel flexible arbitrary waveform generator (AWG). It offers an outstanding combination of high bandwidth and dynamic range which enables generation of wideband signals.
Analog Output - Baseband Operation
The analog output of SDR14TX is DC-coupled and optimized for generation of wideband signals. The dual outputs can be used for generation of two independent channels or generation of complex (IQ) zero-IF modulated signals.
Analog Output - RF Operation
The analog output of SDR14TX can operate in second Nyquist for direct generation of RF signals.
Interface to the Host
SDR14TX connects to the host via a Compact PCI Express / PXI Express interface 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.

Features
Software Development Kit (SDK)
The SDR14TX comes with an easy-to-use API that allows easy integration into any application. Software tools for application development include C/C++, Matlab and DLLs for Windows. The SDK also includes SP Devices´ data capture tool, ADCaptureLab.
FPGA and the ADQ Development Kit
The SDR14TX is built on a Xilinx Virtex 6 LX240T FPGA. The user can access the FPGA and implement customized digital signal processing by purchasing the ADQ Development Kit. This kit contains everything that is needed to get started with the FPGA development, and also includes examples and documentation. See the Firmware development product page for more information.
Generation Functions
The memory of the SDR14TX can hold up to 16 384 different waveform segments. Each segment can be looped for a user-defined number of repetitions. There are several possible trigger configurations that can be used for switching between segments. The segment sequencing can be controlled by an external trigger input and multiple boards can be synchronized for a multi-channel AWG.
There is a 1024-entry playlist table that optionally can be used to create a play order for the segment data. This allows changing the segment order quickly without having to reprogram the actual segment data. The playlist can also generate trigger outputs at specific positions.
There are several ways to generate marker patterns and triggers. The internal trigger generator can trigger the sequences and produce a trigger output signal. The SDR14TX can generate 31 different marker patterns using the 5 GPIO signals. These markers are programmed to follow the segment data. The playlist function can also generate triggers.
When there are long gaps in the data pattern, it is possible to encode commands into the data that will generate a set of zeros. In this way, silent periods in the signal will not waste segment data memory.
