The low cost digital sampling device is an oscilloscope which interfaces with a separate workstation to bring high cost features to a low cost device. By offloading typically hardware driven or processor calculations to existing software, significant engineering time can be reduced to bring an equivalent product to market. The device features a fully analog front end with multiple methods to control gain digitally, as well as an Lattice FPGA for signal processing. An FTDI interface allows easy control over the device while using a standard workstation. The device's analog front end has a bandwidth greater than 50MHz with standard off the shelf components. A PCI-E interface between the analog front end and data side could allow for specialized sensing hardware or an easily upgradeable oscilloscope.
