Description
Velleman PCSGU250is a device for a computer witha USB interface, which is a complete set containing measuring two-channeloscilloscopeandfunction generator. The device is powered directly from the USB port andrequires no additional power supply. The device performs all the tasks of the connectors, contains the input amplifiers and filters, and samples of the measured signal are transmitted in the form of a number to the computer, which performs all the calculations, which greatly increase the speed of measurements. This solution made possible a considerable simplification of the manufacture of the device, and on the oscilloscope screen there are no adjusting elements, because all measuring parameters can be changed usingspecial computer programs.
The app bar.
In addition to the USB port, in the case there arethreeBNC connectors, two of which work as the measurement input, and the third is used for external synchronization.
Sockets
The device also can act as aspectrum analyzer and a wobbulator. Built-infunction generator has 5 preset signals with different waveforms -sine, saw, rectangle, sin(x)/x. There is alsothe option of adding your own signalsby manually entering item by item, or by using those saved in the format *.lib. In addition, there is also a feature "Wave Sequencer"that allows you to performsemi-automatic measurementsby defining your own signal sequence.The device can turn out to be vital during the construction of their own electronic devices.
