Features

Analog Front-End (AFE)
The analog front-end is optimized for high performance:

DC-coupling enables stable baseline and suppress baseline wander for unipolar pulses
DC-offset enables the entire input signal range to be used for unipolar pulses which double the effective number of bits
Single-channel mode at 10 GSPS allows for maximized time resolution
Dual-channel mode at 5 GSPS offers multi-channel capability

SP Devices’ technology for signal quality enhancement
ADQ7DC benefits from by SP Devices’ technologies for signal chain performance enhancement:

The proprietary signal conditioning algorithm ADX eliminate the legacy errors known to degrade the resulting outputs of interleaved digitizers. ADX enables the full potential of time-interleaved ADCs to increase the sampling rate without performance degradation
The baseline stabilizer (DBS) is SP Devices’ core technology for pulse measurements, which enables a reliable reference level with 22 bits precision. This allows for accurate pulse-property measurements

Firmware packages
The ADQ7DC is available with several application-specific firmware packages which include tailored signal processing functions. These firmware packages are designed to meet the requirements of various advanced measurement systems:

Advanced spectrometry and other repetitive measurements are addressed through high-speed interleaving and a firmware including threshold and waveform averaging
Particle physics experiments and other random pulse experiments are addressed through pulse detection and zero compression firmware and combined with synchronization capabilities for multi-channel system support
Software defined radio and other frequency-domain measurements are addressed through firmware including DDC, decimation filter, and continuous streaming

Pulse capture features
The ADQ7DC pulse detection features:

High bandwidth AFE for capturing short pulses
Real-time equalizer filter for custom tuning of the impulse response
High-speed data transfer through PCIe Gen3 x8
DC-offset doubles the dynamic range for unipolar pules
Data driven acquisition firmware for automatic pulse analysis and zero suppression (option FWPD)
Noise suppression firmware with averaging for repeated measurements (option FWATD)

RF system features

The ADQ7DC can operate as a dual-channel Zero-IF receiver with an effective bandwidth of 5 GHz (-2.5 to + 2.5 GHz) using the functions in FWSDR.

ADQ7DC Development Kit for custom firmware
For situations requiring additional flexibility further real-time signal processing is enabled through the open FPGA structure. The user can gain access to the on-board FPGA through the ADQ7DC Development Kit which allows for custom real-time signal processing such as particle classification enhancement, data reduction, etc.

System design with ADQ7DC
ADQ7DC supports numerous features which simplifies system design:

PCI Express interface allows for high-speed data transfer and advanced disk storage solutions and the large on-board FIFO handles burst data and PCI Express scheduling for real-time performance. Since the ADQ7DC is half length, a small chassis may be used to implement a compact self-contained design
The compact USB3.0 form factor allows the digitizer to be placed near the sensor/detector inside the instrument rather than in the host PC. The high data rate and custom firmware processing results in powerful system capabilities that is easy to integrate
10 Gigabit Ethernet (GbE) form factor also allows the digitizer to be placed inside the instrument and offers electrical isolation from the host PC. In addition 10GbE digitizers can be operated from far distance via the fiber connection
The PXIe format is commonly used for modular instruments in rough environments and can easily be used for implementing synchronized multi-module and multi-channel systems for large detector arrays
The MTCA.4 format is frequently used for large-scale integration in applications with high channel count

Synchronization with White Rabbit
White Rabbit is a fully deterministic Ethernet-based network for general purpose data transfer and synchronization which has been developed at CERN. ADQ7DC offers built-in support for White Rabbit allowing for synchronization of multiple boards over large distances.

Data acquisition
ADQ7DC offers continuous and triggered streaming of data to the host PC as well as recording of multiple records in the on-board memory. Triggering can be done using level trigger for data driven triggering and external trigger for scheduled operation. In addition there is also a software trigger for full user control and internal trigger for advanced real-time systems control.
