PicoScope 3000 Series USB-powered PC oscilloscopes are small, light, and portable and can easily slip into a laptop bag while offering a range of high-performance specifications.
These oscilloscopes offer 2 or 4 analog channels and a built-in function / arbitrary waveform generator. MSO models add 16 digital channels. Key performance specifications:
The highpass filter can remove unwanted DC offsets and low-frequency hum from signals. In this example, the input signal is a 1 kHz sine wave superimposed on a linear ramp. Using a simple math channel filter of
HighPass(A,100) we removed the ramp to leave a sine wave with zero offset.
