AC coupling. In this mode, the scope device very low signal frequencies below a few hertz. This allows you to use the full resolution of the scope to measure a.c. signals accurately, ignoring any d.c. offset. You cannot measure the signal level with respect to ground in this mode.

Channel. A scope device has one or more channels, each of which can sample one signal. High-speed scope devices typically have one BNC connector per channel.

DC coupling. In this mode, the scope device measures the signal level relative to signal ground. This shows maximum information about the signal, including d.c. and a.c. components.

Graticule. The pattern of broken grey lines in every scope view window. These help you estimate the amplitude and time of features on the waveform.

Grid. The arrangement of viewports 68 in a capture window. The number of grid rows and the number of grid columns can each be either 1, 2, 3 or 4.

In focus. PicoScope can display several capture windows, but one window is drawn in stronger colours than the others. This is the window that is in focus. When you click a toolbar button, it will usually affect only the window that is in focus. To bring a window into focus, click on it.

Oversampling. Collecting samples at a faster rate than requested, then combining the excess samples by averaging. This technique can increase the effective resolution of a scope device when there is a small amount of noise on the signal.

Probe. An accessory that attaches to your oscilloscope and picks up a signal to be measured. A probe can pick up any form of signal, but it always delivers a voltage signal to the oscilloscope. PicoScope knows about standard probes, but also allows you to define custom probes.

Roll mode. Normally, PicoScope redraws the waveform in a scope view many times every second. At timebases slower than 200 ms/div, however, it switches to roll mode. This causes the waveform to move continuously from right to left, with old data disappearing off the left-hand side and new data being added on the right-hand side. This mode is more convenient for viewing slowly changing data.

Ruler. A vertical or horizontal dashed line that can be dragged into place on a waveform in a Scope View. PicoScope displays the signal level, time value or frequency value of all rulers in a Ruler Legend box.

Scope device. A box of electronics that, with the help of the PicoScope software, turns your computer into a PC Oscilloscope.

Tooltip. A label that appears when you move the mouse pointer over some parts of the PicoScope screen, such as buttons, controls and rulers.

Trigger. A device that detects when the waveform rises or falls past a preset signal level. When this event occurs, the program may begin to acquire data.

View. A presentation of data from a particular scope device. Each scope device may have zero, one or more views, all of which are displayed inside the capture window for that scope device. The only type of view currently available is the scope view.

Viewport. A rectangular space in a capture window that can contain one or more views, or can be empty.
