Design overviewHardware is built around Xilinx Artix-7 FPGA with an onboard RAM available for buffering samples (512 MB DDR3 SDRAM). All hardware settings are controlled via software GUI. USB connectivity is provided via Cypress’s FX3 USB 3.1 Gen1 chip. Hardware is USB powered which eliminates the need for additional power supply. Below you can find more information about individual hardware components.OscilloscopeTwo analog channels are available as oscilloscope inputs. Both oscilloscope channels are protected against overvoltages up to +/- 50 V. Input coupling counters. Sine wave output is generated with the help of CORDIC algorithm which provides arbitrary frequency output. User can also provide a custom waveform sample data and upload it to FPGA internal memory (BRAM).Digital GPIO (Logic Analyzer / Digital Pattern Generator)12-bit digital interface is sampled at 250 Mhz and is logically divided into two 6-bit channel groups. Each channel group can be independently 1,25 V to 3,3 V, but inputs are designed to accept also 5 V. Selected interface voltage is also available on dedicated output pins and can be used as voltage supply. Custom digital samples for pattern generator can be uploaded to FPGA and internal clock divider is available to control the output frequency. It is also possible to override individual outputs with a logic 'LOW' or 'HIGH' at any time.SpecificationsOscilloscopeNo. of Channels: 2Analog bandwidth (-3 dB): 100 MhzSampling rate, max.: 250 MSps dual ch.
