USB Oscilloscope: PC based scope PC based oscilloscopes including USB scopes are able to provide high performance in a small space and for a comparatively low cost by using the processing power of a computer. Scope types includes: Oscilloscope Tutorial Includes: PC based oscilloscopes including USB scopes have become a very popular way of providing a high performance oscilloscope for low cost and in a small package. In may instances a computer will be available in an environment where electronic equipment is to be tested, and therefore using the processing power, screen and power supply of the PC or other computer makes sense, saving on cost and space. Choice of USB for PC scopes Using the Universal Serial Bus, USB for the means of connecting a scope to a PC makes absolute sense, although it not the only method.

It is possible for scopes using personal computers, PCs, to use a variety of methods to link to PCs. However in recent years USB has become standard on virtually all computers and as a result it does not require the use of an additional card like a Firewire card, etc to use one of these oscilloscopes. Using USB means that it is possible to use a scope using the PC processing power on virtually any PC. The other advantage is that having a digital USB scope design enables the advantages and cost savings of quantity can be made. Fewer variants are required for different interfaces, and therefore it is possible to focus on optimising the design for USB. PC USB scope basics One of the key elements of the PC oscilloscope is naturally the USB link. This provides a convenient and sufficiently high speed data link by which the USB scope and computer can communicate.

Although the oscilloscopes from different manufacturers will differ, and USB scopes providing different levels of functionality will naturally be different, there are some common aspects of these scopes that can be outlined. The PC USB scope architecture, as would be expected, has many similarities to that of a standard digital oscilloscope. It is just that a portion of the functionality is contained within the PC.

When the signals enter the scope they enter an analogue section where they are pre-conditioned by amplifying them, attenuating them or adding a DC offset as required. This ensures that the signals are within the required range for the further stages. Velvet serial smotret online sub. The next stage is where the signals are converted into a digital format by analogue-to-digital converters. The sample logic circuitry controls the sampling process and the subsequent storage of the data in a memory area called the capture memory. Like other digital scopes, the USB versions also include triggers which control the start and end of the samples.
