PC oscilloscopes are catching up with their "big brothers" in terms of performance and scope. The supplier Pico Technology is launching the "fastest PicoScope ever" on the market to mark the company's 20th anniversary. With four channels, the USB oscilloscope offers an analog bandwidth of 500 MHz in combination with a sampling rate of 5 GSample/s. In addition, the oscilloscope has integrated function generators, mask limit tests and channel-wise switchable bandwidth limiting and input resistors.
