HS3, HS4, HS5 and HS6 USB data acquisition cards can not only collect data at high speed for display and analysis, but also have a set of powerful analysis software including (digital storage oscilloscope, FFT spectrum analyzer, arbitrary waveform generator, transient\ continuous waveform recorder, digital multimeter, I2C protocol analyzer, CAN bus analyzer, serial port analyzer, J1939 decoding, SM bus, PM bus, TWI bus, Access bus, audio analysis. MIDI, DMX analysis, etc.). The following main functions are illustrated: the software can be downloaded by www.pc17.com.cn.

Oscilloscope function:

The oscilloscope is used to display the voltage of the collected signal, drawing with time (YT) or another signal voltage (XY).

The oscilloscope function in multi-channel oscilloscope software can have one or more large, fully configurable graphics, each of which can display different parts of the signal. The measured signal can be copied to a reference channel to compare the real-time signal with the earlier measured signal.

In the oscilloscope, the cursor can be used for screen measurement, and T = line to indicate the trigger time. The signal can be given a descriptive name, and the legend can be used to simplify the identification of the displayed signal. You can place text labels to mark useful parts of the signal.

In order to display all the details of the measured signal, the oscilloscope provides infinite amplification in both vertical and horizontal directions. All zooming actions can be performed using the undo zooming function.

Spectrum Analyzer function:

Spectrum analyzer is a kind of instrument which uses graphics to display the relationship between signal amplitude and frequency in frequency domain. It will show which frequency components exist in the signal and the strength of those signals.

Through the spectrum analyzer, the small harmonic distortion on the signal can be better displayed than the oscilloscope. The sine wave looks good in the time domain, but the harmonic distortion is visible in the frequency domain.

On the oscilloscope, the noise signal can be regarded as completely random in the time domain, and it can be seen that there is mainly a frequency in the frequency domain of the spectrum analyzer.

In the frequency domain, it is very simple to determine carrier frequency, modulation frequency, modulation level and modulation distortion from a modulated signal (AM or FM).

Multimeter function:

A multimeter is an instrument that measures a signal and then determines one or more specific characteristics of the signal and displays them as numerical values.

The multimeter can be used to measure or monitor the specific characteristics of the signal, such as RMS value, frequency, maximum value, etc. Multi-channel oscilloscope software can have any number of fully configurable displays, or display the measured values as digital or use a graphical multimeter display. When using a graphical multimeter display, it can be very helpful when adjusting the circuit for specific characteristics, such as adjusting the offset to 00:00.

Arbitrary waveform generator function:

An arbitrary waveform generator is an instrument that can generate repetitive or single transmitted signals. In a conventional function generator, the signal can display a sine wave or a square wave in a predefined standard form. However, the signal can also be of any shape customized by the user. These signals can be created using multi-channel oscilloscope software or external programs, or they can be signals previously measured by the oscilloscope and loaded in the generator.

Function generator is an indispensable tool for testing circuits. It can be used to apply the signal to the circuit under test to test the function of the circuit.

One of the specific applications of arbitrary waveform generator is the ability to generate and simulate some external conditions without the ability to have actual conditions. An example of this is the generation of previously measured crankshaft sensor signals and their application to the motor management system of the automobile. The components of the engine management system can be tested without the engine running. In addition, systems that rely on serial communication signals can be tested in this way.

Function of protocol analyzer

A protocol analyzer is a measuring instrument that analyzes one or more signals that communicate between electronic devices according to a specific protocol. The protocol analyzer checks the signal and decodes the transmitted information. Decoding information can be displayed in graphics, analog dashboards, and lists.

The protocol analyzer is a useful tool when developing the hardware and / or software implementation of the communication bus. It can also be used when debugging device or bus failures.

The multi-channel oscilloscope software includes the following protocol analyzers:

CAN bus analyzer

J1939 decoder

I2C analyzer

Serial RS232 analyzer

SPI decoder

Data logger function:

A data recorder is an instrument that directly records a data signal and is used to display the signal voltage, which is drawn according to time (Yt) or another signal voltage (XY).

A data recorder is an ideal instrument for measuring slowly changing signals, such as temperature changes in a room. While capturing the whole process, any changes to the input signal are immediately visible.

Another application of data recorders is to measure long non-repetitive signals, such as serial communication signals, which will last too long to be captured in the internal memory of the hardware.

The general branch HS series multi-channel data analysis software has comprehensive functions, and each function is very perfect and powerful. Combined with HS series USB data acquisition card, almost all acquisition and analysis problems can be solved.

Support secondary development. Supported by Cmax Cure +, C language, Delphi, Java, LabVIEW, Matlab, Python, VB.NET, etc., free UD library-encapsulates low-layer protocols.
