What is a PC-based USB Oscilloscope?

The difference between PC-based USB oscilloscopes (referred to as a USB oscilloscope) and stand-alone oscilloscopes is that a USB oscilloscope does not have buttons or a screen and is connected to a computer through a USB. The device is then controlled by the computer, and results are displayed on the computer screen. The following picture is an illustration of a USB oscilloscope in use:

Advantages of a PC-Based USB Oscilloscope

Compared with stand-alone oscilloscope, PC-Based USB Oscilloscopes have the following advantages:

1. Small size, easy to carry.
2. PC screen is larger so the waveforms can be seen more clearly.
3. No screen component so the price is lower.
4. PC interface makes it easy to process and edit files.
5. Users can design their own programs to control the oscilloscope.

Features of the Perytech USB Oscilloscope

Feature 1: User-Friendly Interface

Many USB oscilloscope software use a conventional window design because it is the easiest to design. However, such a design does not comply with the actual use of oscilloscopes and causes difficulties and inconvenience for users.

The software design of Perytech’s USB oscilloscope is similar to that of an actual oscilloscope, as depicted in the following screenshot. The interface is extremely user friendly, and most users can operate all the functions even in the absence of a user manual.

The software panel can be displayed in five sizes or be displayed in the full screen mode.

Feature 2: Powerful Software Function

The software includes many automatic measuring functions, such as maximum value, minimum value, frequency, and period.

The cursor function is useful and convenient for developing reports.

In the overview function, the top of the screen shows the entire waveform and the magnified portion of the waveform is shown below that. The grey area can be dragged at the top or the scroll bar at the bottom can be used to change the section displayed.

The FFT function automatically detects peak values. The FFT function can be turned on to view the frequency domain.

The equivalent sampling function: for periodic signals, this function analyzes signals and graphs them at a sample rate of 4 GS/s. It increases the sampling resolution and provides the user with more details.

The oscilloscope software has numerous math functions such as add, subtract, multiply, divide, and square.

Lissajous curve, displayed in the X-Y mode.

The frequency counter function has a precision of 0.1 Hz

The save function enables users to save files as *.png, *.bmp, or *.csv for Excel files and *.txt or *.m for MATLAB files. The below figure is using the MATLAB "plot()" function to draw a graph of the wave.

Feature 3: Stacking Function

The stacking function is used to combine multiple oscilloscopes. Up to four USB oscilloscopes can be stacked as an 8-channel oscilloscope.

Feature 4: Logic Analyzer Mode: Easy to Decode Digital Protocol

The logic analyzer mode can decode bus data and save development time. This Mode can decode common protocol such as: I2C, UART, I2S, PS2, CAN Bus, 1-Wire, S/PDIF, Lin Bus, Microwire, Miller, Manchester, SM Bus, and Modbus. Will continue to be added and free update.

The logic analyzer mode provides a “packet list” function. This function can display the packet in a window so that more data can be observed in one window. The following screenshot displays the decoded I2C bus and packet list.

Feature 5: Provides LabVIEW API

LabVIEW can be used to design a measurement program.

Feature 6: Stylish Minimalist Appearance, Slim and Light

Perytech USB Oscilloscope comprises a black aluminum alloy case with an excellent texture. The alloy case receives hair-line surface treatment to ensure the exterior is very trendy. The exterior is very trendy, with great texture. The device is small, light, and convenient to carry.

The front and rear panels are laser engraved. This is not only aesthetic but does not have paint peeling problems in the future.

What is the Difference between Perytech USB oscilloscopes and Other Low-priced Oscilloscopes?

The following table compares the Perytech USB oscilloscope with other low-priced oscilloscopes. The Perytech model is based on the DSO-2100.
