UNI-T UPO1082HD Digital Oscilloscope User Manual

1. Product Overview

The UNI-T UPO1082HD is an 80 MHz, 2-channel digital oscilloscope featuring 12-bit resolution and a 1.25 GSa/s sampling rate. This instrument is part of the UPO1000HD series, designed for precise signal analysis in various applications.

Key features include:

• 12-bit High Resolution: Provides 16 times more vertical detail than standard 8-bit oscilloscopes for enhanced measurement precision.
• Deep Memory and Fast Capture: 100 Mpts memory depth for long signal acquisitions without reducing the sampling rate, and a waveform capture rate of 1,000,000 Wfms/s to reveal rare glitches and intermittent anomalies.
• Integrated Protocol Decoding: Built-in serial bus analysis for UART, I2C, SPI, CAN, and LIN, with time-correlated decoding overlay on waveforms for simplified system debugging.
• Touchscreen Interface: A 7-inch capacitive touchscreen with gesture control for intuitive waveform navigation.
• Connectivity: USB, LAN, and HDMI connectivity for versatile laboratory integration.
• Multi-functional: Integrates seven tools including oscilloscope, spectrum and protocol analyzers, DVM, frequency meter, power analysis, and logic functions.
• Portable Power: Can be powered via USB-C, offering portability.

2. Setup Instructions

1. Unpacking: Carefully remove the oscilloscope and all accessories from the packaging. Verify that all components listed in the packing list are present, including probes, power cable, and documentation.
2. Power Connection: Connect the provided power adapter to the USB-C port on the rear of the oscilloscope and then to a suitable power outlet. Alternatively, for portable use, connect a compatible USB-C power bank.
3. Initial Power On: Press the power button located on the front panel. The device will perform a self-test and boot up.
4. Probe Compensation: Before taking measurements, it is recommended to compensate the probes. Connect a probe to Channel 1 (CH1) and attach the probe tip to the 'Probe Comp' output and the ground clip to the ground terminal. Adjust the probe compensation screw until a perfect square wave is displayed on the screen. Repeat for other probes and channels as needed.

3. Operating Instructions

3.1 Basic Waveform Display

• Connecting Signals: Connect your signal source to the desired input channel (CH1 or CH2) using a BNC cable and probe.
• Auto Set: Press the Auto button to automatically adjust the vertical and horizontal settings for a stable waveform display.
• Manual Adjustments: Use the vertical (Volts/Div) and horizontal (Sec/Div) knobs to manually scale the waveform. The position knobs allow you to move the waveform vertically and horizontally.
• Triggering: Use the trigger controls to stabilize repetitive waveforms. Adjust the trigger level and mode (Edge, Pulse, Video, etc.) as needed.

3.2 Advanced Features

• Touchscreen Navigation: Utilize the 7-inch capacitive touchscreen for intuitive control. Pinch-to-zoom, drag-to-pan, and tap-to-select gestures simplify waveform analysis and menu navigation.
• Protocol Decoding: Access the protocol decoding functions via the menu to analyze serial bus communications (UART, I2C, SPI, CAN, LIN). Configure the bus parameters and view decoded data directly on the screen.
• Measurement Functions: Press the Measure button to display automatic measurements such as frequency, period, Vpp, Vrms, etc.
• Storage and Connectivity: Use the USB port to save waveforms and screenshots to a USB drive. Connect via LAN for remote control and data transfer. The HDMI output allows for external display connection.

4. Maintenance

• Cleaning: Use a soft, dry cloth to clean the exterior of the oscilloscope. For stubborn dirt, a slightly damp cloth with mild detergent can be used. Avoid abrasive cleaners or solvents.
• Probe Care: Handle probes carefully. Avoid bending or stressing the probe tips and cables. Store probes in a clean, dry place when not in use.
• Ventilation: Ensure that the ventilation grilles on the sides and rear of the device are not obstructed to prevent overheating.
• Software Updates: Periodically check the UNI-T website for firmware updates to ensure optimal performance and access to new features.
