Overview
The SDR14 is a dual channel flexible digitizer combined with dual channel signal generation. SDR14 offers an outstanding combination of high bandwidth and dynamic range, which enables demanding measurements such as RF/IF sampling and generation
of very wide band signals. The high sampling rate is enabled by SP Devices' proprietary interleaving technology ADX.
Analog Input (AFE)
The analog input of SDR14 is AC-coupled and optimized for spectral purity over a wide bandwidth. The frequency band is 10Hz to 500MHz, which enables sampling of wide band signals. The outstanding dynamic range enables measurement on multi systems
radio channels. The two outputs can be used for either two separate channels or sampling of an IF from a complex mixer.
Analog Output (AFE)
The analog output of SDR14 is AC-coupled and optimized for generation of wide band signals. The dual outputs can be used for generation of 2 independent channel or generation of complex signals.
The analog output is also available in a DC coupled version for generation of Zero IF signals.
Interface to the Host
The digitizer connects to the host via a Compact PCI Express / PXI Express or MTCA.4 µTCA 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 SDR14 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 XP/Vista. The SDK also includes SP Devices´ data capture tool,
ADCaptureLab.
FPGA and the ADQ Development Kit
The SDR14 is built on the ADQ DSP computational board which employs 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 ADQ DSP product page for
more information.
Acquisition Functions
Standard trigger options are external, internal, software and level trigger. For PXIe units the backplane triggers are also available. The multi-record mode can be combined with any trigger function. Every record is tagged with a header containing
time stamp (timing information), record counter, trigger counter and the trigger type for the record.
As standard on the SDR14, there is also an averager function available that performs on-board averaging of waveforms.
Generation Functions
The generator is based on single shot or continuous transmission of waveforms from onboard RAM. The trigger of the data pattern is linked to the trigger of the acquisition to synchronize transmission and reception.
A loopback function is available, where received data is retransmitted. Real time signal processing can be applied on this data through the ADQ Development kit.
There is also a playlist mode available which allows the segment playlist to be changed from the host also while running the waveform generation. You can change either the order of segments, number of repeats of each segments, triggering modes
and also the data for the segments - on the fly while playing waveforms. Please check out the App Note for this powerful functionality.
