PicoScope 7 Software
Available on Windows, Mac and Linux
PicoScope dedicates most of its display area to a scope view, which is a conventional plot of voltage against time.
All the controls you need are arranged around the display area seperated into channel controls and tools (left) and PicoScope controls and software buttons (top).
The x-axis measures time. It is marked along the bottom in multiples of seconds.
The PicoScope starts capturing at 0 s, by default this is in the centre of the graph (50% pre-trigger) to move the start position along the x-axis, drag the yellow trigger marker left or right or change the pre-trigger in the trigger menu.
The trigger can be adjusted in the vertical direction to adjust the voltage level the PicoScope starts capturing at. This can be adjusted by the trigger lozenge or by moving the trigger marker up or down.
The timebase sets the time interval across the horizontal axis. By default it is scaled in time per division. As there are ten horizontal divisions, the total collection time is 10 times the time per division.
To change the timebase and sampling settings, use the +/- buttons or open the timebase lozenge on the top row.
The y-axis usually measures voltage (although it can be scaled using a Custom Probe or other BNC probes to show other quantities such as amps or pressure).
To make the most out of the hardware resolution, adjust the voltage range to the smallest value that still displays the full captured waveform. This will allow the PicoScope to have the most resolution points providing more detail in the Y-axis in the waveform.
Once the correct range has been selected, the user can adjust the scaling, offset and ordering of each channel to optimise the graph view for multiple signals.
Each channel has a y-axis that can be dragged up or down with the mouse to change the offset, or hover and scroll on the axis to adjust the visual scaling (different to adjusting range). This can also be changed in the Display tab of each channel.
Along with the mouse opperation on the y-axis, a user can adjust the scaling and offset in the channel settings. To find this open the Channel → Display and adjust the scaling and offset in the numeric boxes labeled respectively.
The order of each channel can be adjusted by using the mouse to click on the channel axis. This will bring the selected channel to the top and is useful when trying to align traces in the graph area.
To auto-arrange or reset channel offset and scaling, go to More... → Views and under Axis layout, click Auto-arrange or Reset.
The rulers can be dragged into place on the scope view to display time and voltage measurements. When not in use, only the ruler handle is shown, in a color matching the trace. Up to two rulers can be dragged into place for each channel.
The ruler legend shows measurements for all rulers in use. Where pairs of rulers are used, the legend also shows the difference (delta) between them. The lock button ties the two rulers together so that you can drag them without altering the delta between them.
If two time rulers are positioned, an additional frequency legend shows the inverse of the time difference between them. The units can be set to either hertz or RPM.
PicoScope has too many advanced controls to describe on this page. Please see below for further information:
