The GX3722 is a user configurable, FPGA-based, 3U PXI card which employs a multi-function, analog / digital, I/O daughter board. The module offers multiple analog and digital source / measure capability. The daughter board interfaces to the GX3700 FPGA baseboard which employs the Altera Stratix III FPGA.
The GX3722 offers the following capabilities:
4 channel programmable square wave generator.
4 channel time interval counters.
4 differential TTL outputs.
4 differential TTL inputs.
2 channel function generators.
2 channel digitizers.
3 open drain outputs.
The square wave generators can support frequencies up to 8 MHz and feature high bandwidth signal performance. The time interval analyzers employ high bandwidth comparators and can operate to 10 MHz. The function generators provide sinewave and arbitrary waveform capability. Maximum frequency of operation is 20 KHz. The two channel, 12 bit, 10 MS/s digitizer includes signal conditioning.
The module has access to all of the PXI bus resources including the PXI 10 MHz clock, the local bus, and the PXI triggers; allowing the user to create a custom instrument which incorporates all PXI bus resources. Control and access to the FPGA is provided via the GX3722's driver which includes the ability to download compiled FPGA code as well as perform register reads and writes.
