PicoScope 2000 Series. A range of low-cost PC Oscilloscopes that includes the

PicoScope 2202, 2203, 2204 and 2205 two-channel oscilloscopes and the PicoScope

2104 and 2105 handheld oscilloscopes.

PicoScope software. This is an application that accompanies all our PC Oscilloscopes.

Although you do not need it if you are writing your own application, you should install

it anyway, because it includes the drivers that you will need to control the

oscilloscope.

Real-time continuous mode. A sampling mode in which the software repeatedly

requests single samples from the oscilloscope. This mode is suitable for low sampling

rates when you require the latest sample to be displayed as soon as it is captured.

Streaming mode. A sampling mode in which the oscilloscope samples data and

returns it to the computer in an unbroken stream. This mode of operation is suitable

when the input signal being sampled contains only low frequencies.

Timebase. A number that is supplied to the driver to specify a sampling rate for the

oscilloscope. Each oscilloscope model has a different range of possible sampling

frequencies, as specified in the User's Guide for that model.

USB 1.1. An early version of the Universal Serial Bus standard found on older PCs.

Although your PicoScope will work with a USB 1.1 port, it will operate much more

slowly than with a USB 2.0 or 3.0 port.

USB 2.0. Universal Serial Bus (High Speed). A standard port used to connect external

devices to PCs. The high-speed data connection provided by a USB 2.0 port enables

your PicoScope to achieve its maximum performance.

USB 3.0. A faster version of the Universal Serial Bus standard. Your PicoScope is fully

compatible with USB 3.0 ports and will operate with the same performance as on a

USB 2.0 port.

Vertical resolution. A value, in bits, that indicates the number of input voltage levels

that the oscilloscope can distinguish. Calculation techniques can improve the effective

resolution.

Voltage range. The range of input voltages that the oscilloscope will measure in a

given mode.
