The **Hantek MSO2000 series** (specifically the MSO2C models) is a range of mixed-signal oscilloscopes. These devices are popular among hobbyists and engineers because they combine a digital storage oscilloscope (DSO) with a logic analyzer. Below is a breakdown of the electronic components and technical specifications that define the MSO2C series. --- ### 1. Core Technical Specifications The "MSO2C" designation generally refers to the **2-channel analog** versions with an integrated **logic analyzer** (though they often lack the built-in waveform generator found in the "D" models). | Feature | Specification Details | | :--- | :--- | | **Analog Channels** | 2 Channels | | **Bandwidth** | 100MHz, 150MHz, or 200MHz (Model dependent) | | **Real-time Sample Rate** | 1GSa/s (Single channel), 500MSa/s (Dual channel) | | **Logic Analyzer** | 16 Digital Channels | | **Memory Depth** | 8Mpts (Standard) | | **Vertical Resolution** | 8-bit ADC | --- ### 2. Internal Electronic Architecture The MSO2C functions through several key electronic subsystems: #### A. The Analog Front-End (AFE) This is the most critical part of the signal chain. It consists of: * **High-impedance Attenuators:** Resistor networks that scale high-voltage signals down to levels the internal circuitry can handle. * **Operational Amplifiers (Op-Amps):** High-speed amplifiers that buffer and condition the signal. * **Relays:** Mechanical or solid-state switches used to change range settings (e.g., volts/div). #### B. Data Acquisition System * **ADC (Analog-to-Digital Converter):** Converts the continuous analog voltage into discrete digital values. The MSO2C typically uses high-speed interleaved ADCs to achieve the 1GSa/s rate. * **FPGA (Field Programmable Gate Array):** The "brain" of the data processing. It handles the high-speed data stream from the ADC, triggers, and manages the circular memory buffer. #### C. Logic Analyzer Interface * **Digital Input Buffer:** A 16-pin connector interface that uses high-speed comparators to distinguish between high (1) and low (0) logic levels based on a user-defined threshold. --- ### 3. Display and User Interface * **LCD Panel:** Usually a 7-inch TFT color display with a resolution of 800x480 pixels. * **Rotary Encoders:** Used for physical knobs (Vertical, Horizontal, Trigger) to provide tactile feedback to the user. * **Processor:** A secondary ARM-based microprocessor typically handles the Linux-based Operating System, USB communication, and the Graphical User Interface (GUI). --- ### 4. Connectivity Ports The MSO2C includes standard industry interfaces: 1. **USB Host:** For connecting thumb drives to save screenshots or CSV data. 2. **USB Device:** For PC connectivity (SCPI commands or using the Hantek software). 3. **Trigger Out / Pass-Fail:** BNC output for synchronizing with other laboratory equipment. --- ### Summary Table: MSO2C vs. MSO2D | Component | MSO2C | MSO2D | | :--- | :--- | :--- | | **Oscilloscope** | Yes | Yes | | **Logic Analyzer** | Yes | Yes | | **Function Generator** | **No** | **Yes (1CH 25MHz)** | | **Price Point** | Lower | Higher |
