Overview
The ADQ 112 digitizer features single channel, 12-bit resolution, 1.1 GSPS capture rate with 780 MHz analog input bandwidth, and a memory buffer of 170 MSamples. The unique sampling rate is enabled by SP Devices’ ADC interleaving technology, ADX. Read more about ADX here. The combination of high speed, high resolution and wide bandwidth makes it ideal for broadband applications such as IF sampling of RF signals and high-speed data recording. Excellent spectral purity in combination with low noise also makes the ADQ 112 ideal for noise measurements.
Analog Front End (AFE)
In its default configuration, the ADQ 112 comes with an AC-coupled AFE with a lower cut-off frequency of 10 Hz, but several options are available such as a DC AFE which uses amplifiers, or a low frequency AC coupled AFE. See the ADQ112 Datasheet for further details and for ordering information.
Interface to the Host
The digitizer connects to the host via a high-speed USB 2.0 cable or through an optional Compact PCI Express / PXI Express interface. All interface types allows for streaming of data at high transfer rates.
Software Development Kit (SDK)
The ADQ 112 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.
FPGAs and the ADQ Development Kit
The ADQ 112 employs two Xilinx Virtex 5 FPGAs. The first FPGA, a XC5VSX50T-3, runs the SP Devices’ interleaving algorithm. The second FPGA, a XC5VLX30T-1, handles the data management, such as DRAM, host communication, triggers and control. This FPGA is opened to the user through the ADQ Development Kit for implementation of customized signal processing. This kit contains everything that is needed to get started with the FPGA development, and also includes examples and documentation. FPGA upgrades are available for demanding real time signal processing tasks.
Acquisition Functions
Standard trigger options are external, software and level trigger. The ADQ 112 supports single and multiple records. The multiple records mode can be combined with any trigger function. A time stamp function tags each record with timing information. Enhanced trigger accuracy gives trigger time on sub sample level.
