Digital Storage Oscilloscope (DSO)
is often regarded as a necessary tool that is designed to analyze complex signals or debug electronic devices. We call it DSO
as the signals are sampled and then stored into memory, which makes it easier to examine them and their relationships.
Actually, digital storage oscilloscope
is a special computer containing a lot of fast A/D converters and software for analyzing and visualizing the signals. You can solve the problem of deploying short-term signals and glitches with DSO. It just relies on the settings and trigger conditions to capture the exact moment. You don’t need to worry too much about the storage capacity, only if you need it to store longer intervals.
Nowadays, PC based digital storage oscilloscope has grasped people’s eyes. You can call them virtual oscilloscope
or analog oscilloscope
. It’s a kind of software that runs on a PC with appropriate interface, which is usually a small box with a fast A/D converters connected to the parallel or USB port, for analog signals.
PC based DSO has many advantages over traditional DSO. A major advantage of virtual DSO is the ability to update software. You can erase the errors and get new functions just by installing the new version.
What’s more, the software’s capabilities are only limited by the interface and computer resources. In this case, you are able to monitor multiple channels in real time, analyze FFT spectrum and decode buses like SPI, I2C, UART or JTAG.
Another thing is, the physical limitations of a PC oscilloscope are defined primarily by the external hardware which is used to sample analog or digital signals. The number of the channels, bandwidth, sample rate and its memory size is the main element that defines the capabilities of PC DSO. The buffer will transfer the stored sampled data to the PC to analyze and then display the data. Therefore, the buffer should be large enough to store all the samples before transferring.
The average price of a PC DSO is lower than that of a real digital storage oscilloscope, but higher than the price of the PC where it runs. However, PC Based Digital Storage Oscilloscope
is a portable and universal tool that enables you to analyze arbitrary signals, to decode popular serial protocols and to store signals for later processing. No matter you do it as a hobby or for professional use, you will find it very practical. It deserves your investment.
