The Instek MPO-2202P Multi-Function Programmable Digital Storage Oscilloscope is named after the abbreviation of Multi-Function Programmable Oscilloscope. Primarily, while it functions as an oscilloscope, this unit also includes the functionality of a spectrum analyzer, arbitrary waveform generator, digital multimeter, and DC power supply. In addition to the five-in-one multi-functional architecture, the introduction of the Python script function into the unit allows for users to conduct program control of a small automated test system by setting up a single unit test or multi-unit test without a PC.

The MPO-2202P is a professional version model of the MPO-2000 series units. In terms of bandwidth, the professional version offers 200 megahertz. The professional version provides larger program memory and more system resources to achieve the ability to process longer waveform data. The professional version provides USB CDC device control to meet the needs of multi-unit collaborative tests. A Python GUI library is provided to allow users to modify the original built-in Python APP or write their own programs that present curve drawing and GUI operation menus to be packaged into Python programs developed by third parties. In addition, the professional version provides more diverse bus decoding functions, including FlexRay, USB-PD, and I^2S.

The MPO-2202P features a built-in Python GUI library for expanded capabilities. Users can build their own test systems and a variety of executable Python APPs are built-in. The all-in-one instrument is ideal for test and measurement automation teaching courses, small-scale automated test of production lines, component tolerance testing for quality assurance, and diversified test applications. The MPO-2202P aims to solve product test needs for repeatability and diversity along with improving the demand for simple and repetitive work efficiency and single-unit program control or the requirement of uploading test results to the cloud.

In the survey of top programming languages on GitHub in 2022, Python was reported to be second only to JavaScript in web-related applications and second in the most popular programming language. The number of users of Python continues to grow and the entry threshold for learning the language is low. For beginners, the syntax is relatively simple and easy to learn. Python has become an increasingly common programming language, thus Python was chosen to be imported into the MPO-2202P to expand the program control applications.

The Python APP currently installed on the MPO-2202P includes the categories of BJT output characteristic curve, LC oscillator circuit frequency and temperature characteristic curve, fuse endurance test, LED forward bias characteristic curve, and barcode scanner measurement application.

On the MPO-2202P, users can modify or call the script of the drawing library. This allows for the user to modify the program by themselves to meet the testing of different DUTs. In addition, other manufacturers can use the built-in AWG function of the oscilloscope to achieve similar effects, but the voltage and power of this kind of AWG are too small along with low practicality. One single MPO-2202P unit can meet the IV test requirements of parts suitable for voltages below 20 volts.

The MPO-2202P is a five-in-one instrument that provides seven innovative functions to extend diverse applications. The seven innovative functions include Python script execution, component tester I-V curve, MQTT protocol, series bus decoding, spectrogram, Python GUI library, and USB CDC-ACM USB.

Python Script Execution

The maximum number of installable python APPs are up to 100 sets and includes pre-installed Python APPs. Running Python source code (.py file) is possible from an internal disk or USB flash disk.

Component Tester I-V Curve

This unit provides I-V characteristic curve (Curve Tracer) with readout scale. The transistor characteristic curve is the first application after completing the Python software platform. The MPO-2202P is used to implement the Curve Tracer function application. The XY mode can be used for waveform accumulation. Users can utilize the two built-in 20 volt DC power outputs of the unit. This professional version model can use an external DC power supply through USB CDC-ACM.

Supports MQTT Protocol

The MPO-2202P also supports MQTT (Message Queuing Telemetry Transport) protocol. For publishers, measurement data can be transmitted to the cloud. For subscribers, remote control of an oscilloscope can be realized.

Serial Bus Decoding

The MPO-2202P provides CAN FD, USB 2.0 (FS), FlexRay, USB PD, and I^2S decoding in this professional version model. No additional options are required for decoding and analysis of new automotive, USB, and audio protocols.

Dual Channel Spectrum Analyzer with Spectrogram

Other than signal measurement on time domain, the MPO-2202P also provides the frequency domain measurement and operation which are both similar to a spectrum analyzer. The dual channel spectrum analyzer and spectrogram are equipped. Users can measure and analyze dual channel frequency domain signals at the same time. The spectrogram function allows users to easily observe the signal's strength distribution and the relationship of the spectrum distribution over time. The dual spectrum analyzer and spectrogram can test the frequency response of low frequency VHF wireless communication, audio processing, vibration analysis, abnormal resonance of mechanical equipment, and more.

Supports Python GUI Library

The professional version model of the MPO-2202P can execute Python APP, with scale, with GUI drawing mode and the parameters can be modified to accommodate the testing of different parts to be tested. Furthermore, this unit allows for users to modify the script from the drawing library themselves. The Python GUI library can be used to draw scaled charts.

Supports USB CDC-ACM to Achieve Multi-Unit Collaborative Test

The MPO-2202P allows for both single-unit and multi-unit collaborative tests in which no additional computer is required. Users only need to plug in an USB keyboard to program on the unit and the measurement results can be presented in charts. The measurement results can also be saved as a CSV or image file along with being uploaded to the cloud. The unit is equipped with Python Script Execution (Edge Computing) which has the function of Python script execution to implement edge computing.
