In addition to the basic instrument, most oscilloscopes are supplied with a probe. The probe connects to any input on the instrument and typically has a resistor of ten times the oscilloscope's input impedance. This results in a 0.1 (‑10×) attenuation factor; this helps to isolate the capacitive load presented by the probe cable from the ...
A passive oscilloscope probe with a switch in the probe handle that selects 1× or 10× attenuation To minimize loading, attenuator probes (e.g., 10× probes) are used. A typical probe uses a 9 megaohm series resistor shunted by a low-value capacitor to make an RC compensated divider with the cable capacitance and scope input.
Tektronix 7854 oscilloscope with curve tracer and time-domain reflectometer plug-ins. Lower module is a mainframe of the series Tektronix TM500 and has a digital voltmeter, a digital counter, an old WWVB frequency standard receiver with phase comparator, and function generator.
For example, the command to set the trigger mode of an instrument to "normal" may be given as "TRIGger:MODe NORMal". Here, the word " NORMal " is used as the argument to the " TRIGger:MODe " command. When multiple arguments are provided, the arguments are written as a comma-separated list.
PicoScope for Microsoft Windows is the full-featured oscilloscope application, and was first released in 1992 by Pico Technology.PicoScope software enables real-time scope display with zooming and panning, and buffers captured waveforms on the PC to enable engineers to view previous measurements.

The first step of computing an eye pattern is normally to obtain the waveform being analyzed in a quantized form. This may be done by measuring an actual electrical system with an oscilloscope of sufficient bandwidth, or by creating synthetic data with a circuit simulator in order to evaluate the signal integrity of a proposed design.
Clipping can be detected by viewing the signal (on an oscilloscope, for example), and observing that the tops and bottoms of waves aren't smooth anymore. When working with images, some tools can highlight all pixels that are pure white, allowing the user to identify larger groups of white pixels and decide if too much clipping has occurred.
