Callback. A mechanism that the PicoScope 6000 driver uses to communicate asynchronously with your application. At design time, you add a function (a callback function) to your application to deal with captured data. At run time, when you request captured data from the driver, you also pass it a pointer to your function. The driver then returns control to your application, allowing it to perform other tasks until the data is ready. When this happens, the driver calls your function in a new thread to signal that the data is ready. It is then up to your function to communicate this fact to the rest of your application.

Driver. A program that controls a piece of hardware. The driver for the PicoScope 6000E Series oscilloscopes is supplied in the form of 32-bit and 64-bit Windows DLLs called ps6000a.dll. These are used by your application to control the oscilloscope.

PicoScope 6000E Series. A range of PC Oscilloscopes from Pico Technology, with a maximum sampling rate of up to 10 GS/s. Sampling resolutions range from 8 to 12 bits and capture memory sizes from 1 to 4 GS.

PRBS (pseudo-random binary sequence). A fixed, repeating sequence of binary digits that appears random when analyzed over a time shorter than the repeat period. The waveform swings between two values: logic high (binary 1) and logic low (binary 0).

USB 2.0. The second generation of USB (universal serial bus) interface. The port supports a data transfer rate of up to 480 megabits per second.

USB 3.0. A USB 3.0 port uses signaling speeds of up to 5 gigabits per second and is backwards-compatible with USB 2.0.
