Control wavefunction generation from a PicoScope. Note that this block requires the CONNECTION_2000 block. Also note that the P2000 blocks require a device specific driver/SDK downloaded from: https://www.picotech.com/downloads. Params: offset_voltage : int The offset (vertical) voltage, in uV (microvolts). amplitude : int The peak-to-peak amplitude, in uV (microvolts). wave_type : select The type of waveform to generate (e.g. 0 is a sine) start_frequency : int The static or starting frequency, in Hz. end_frequency : int The ending frequency if sweeping is activated, in Hz. sweep_increment : int The increment to increase frequency during sweeping, in Hz dwell_time : int = 1, The time to dwell at a frequency during sweeping, in ms. sweep_type : Literal["0", "1", "2", "3"] = "0", The type of sweeping. 0 deactivates sweeping. sweeps : int = 0, The number of sweeps. Returns: out : String Placeholder return currently
