TI and SiLab is so paranoid about samples these days, they pissed me off enough to avoid using their products. Silicon is cheap these days, but shipping out samples costs labour. Posted in Tool Hacks Tagged fpga, open source, oscilloscope Post navigation Labtool even boasts some similar features. WeвЂ™ve looked at several low-cost scope options before. The output voltage can be set, but inputs are 5 V tolerant.ДЄccording to the developer, you can build the scope from the information provided by using free sample chips from the various vendors, only paying for the small components and the cost of the PCB.

Generator channels have 50 Ohm internal impedance and also operates via the GUI using the same USB chip.В The FPGA generates signals atВ 50 Mhz using counters, algorithms, or simple waveform data and feeds a DAC.ДЄ 16-bit digital interface can be set as inputs or outputs. There are also two generator outputs with short circuit and overvoltage protection ( +/- 50 V ). The FPGA samples atВ 100 Mhz through a 10-bit dual analog-to-digital converter ( ADC ).В The FPGA handles triggering and buffers the input before sending the data to the host computer via the USB chip. Both oscilloscope channels are protected for overvoltage up to +/- 50 V. A GUI uses aВ CypressвЂ™s EZ-USB FX2LP chip to send configuration data to the FPGA. The hardware uses aВ Xilinx Spartan-6 FPGA. The control GUI can work with Windows, Linux, or the Mac (see the video, below). The device is a capable 2-channel scope, a logic analyzer and also a waveform and pattern generator. A case in point is the Scopefun open hardware project. Then again, modern scopes often have multiple functions, so maybe thatвЂ™s not a fair assertion.

If you could only own one piece of test equipment, it should probably be an oscilloscope.
