PX1500-4 Digitizer Board, 3.0 GS/s, Xilinx Virtex-5 FPGA
The PX1500-4 is a four channel waveform capture board that can acquire up to 1.5 GS/s on each channel, or up to 3 GS/s for dual channel operation when ADC data is interleaved. The PX1500-4 analog front end is hardware configured to use either a transformer coupled front end or an amplifier connection. The transformer connection can only be set for an AC-coupled input configuration and has a signal frequency capture range of 5 MHz to 2 GHz. The amplifier connection can be set for either AC or DC-coupled input configuration with a signal frequency capture range up to 1 GHz.
The PX1500-4 is designed to maximize the quality of the captured signal in terms of signal-to-noise ratio and spurious-free dynamic range over a very wide frequency range. For this reason, there are no switch components in the analog signal path or bandwidth limiting programmable gain amplifiers; giving customers the benefit of a nearly direct path to the ADC from either the amplifier or transformer coupled input.
A frequency synthesized clock allows the ADC sampling rate to be set to virtually any value from 200 MHz to 1.5 GHz, offering maximum flexibility for sampling rate selection. This frequency selection flexibility comes at no cost to the acquisition clock quality/performance when locked to either the onboard 10 MHz, ±5 PPM reference clock or to an externally provided 10 MHz reference clock. The ADC may also be clocked from an external clock source.
The PX1500-4 has a total of 2 GB memory for onboard sample data storage. Alternatively, PCIe Buffered Acquisition mode utilizes the onboard RAM as a FIFO to provide non-stop continuous acquisition and streaming of sample data to the host PC via the PCIe interface. With PCIe Buffered Acquisition mode, the PX1500-4 can sustain up to a maximum 1.4 GB/s data streaming rate over its PCIe Gen1 x8 interface to the host PC for real-time high-speed processing and/or data recordings.
The PX1500-4 also provides an option for an upgraded secondary Xilinx Virtex-5 SX95T FPGA for embedded signal processing on channels 3 and 4 inputs. FPGA processing models of the PX1500-4 include a FIR Filtering feature standard for these inputs. The processing FPGA is fully end user programmable, allowing for custom developed embedded processing routines.
Up to five PX1500-4 digitizers can be setup for synchronous acquisition operations for a total of 20 input channels by utilizing the separate Signatec SYNC1500 clock/trigger driver source card.
A Windows oscilloscope program, the PX1500 Scope App, allows the operator to view/edit all digitizer hardware settings as well as record and display acquisition data. It is included along with a full complete C SDK for custom application development.
