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 ...
Flying leads are likely to pick up interference, so they are not suitable for low-level signals. Furthermore, the inductance of flying leads make them unsuitable for high frequency signals. Instead, a specific scope probe is used, which uses a coaxial cable to transmit the signal from the tip of the probe to the oscilloscope. This cable has two ...
When the counter reaches zero, the trigger output is set. A 10 inputs NOR gate is more sufficient than a 10 bits digital comparator, but evaluating several lines per picture is no longer possible. Decreasing the line number by one, the carry bit of the counter can be used as trigger output, replacing a 10 inputs NOR-Gate .
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.
A PC-based oscilloscope is a type of digital oscilloscope which relies on a standard PC platform for waveform display and instrument control. In general, there are two types of PC-based oscilloscopes
Measuring ESR can be done by applying an alternating voltage at a frequency at which the capacitor's reactance is negligible, in a voltage divider configuration. It is easy to check ESR well enough for troubleshooting by using an improvised ESR meter comprising a simple square-wave generator and oscilloscope, or a sinewave generator of a few tens of kilohertz and an AC voltmeter, using a known ...
