4. Setup
4.1 Unpacking è Inspection
Upon receiving your UPO1102 oscilloscope, carefully unpack all components and inspect them for any signs of damage. Retain the packaging for future transport or storage.
Accessori standard:
- Oscilloscope Probe (UT-P04) x 2
- Cordone d'alimentazione
- USB2.0 Printing Cable
- English Download Guide
- Multi-language Safety Manual
- Calibration Report (COC)
4.2 Cunnessione di putenza
- Ensure the oscilloscope is placed on a stable, level surface with adequate ventilation.
- Connect the provided power cord to the AC power input on the rear panel of the oscilloscope.
- Inserite l'altra estremità di u cavu di alimentazione in una presa di corrente CA cun messa à terra.
- Appughjà u buttone d'accensione nant'à u pannellu frontale per accende l'oscilloscopiu.
4.3 Cunnessione è Compensazione di a Sonda
Before taking measurements, it is crucial to compensate the probes to ensure accurate readings.
- Connect a probe to one of the input channels (CH1 or CH2) on the front panel.
- Connect the probe tip to the "Probe Comp" terminal and the ground clip to the ground terminal next to it.
- Press u Auto button. The oscilloscope will automatically adjust the settings to display the compensation signal.
- Observe the square wave displayed on the screen. If the waveform is not a perfect square (over-compensated or under-compensated), adjust the trimmer on the probe body using a non-metallic tool until a flat-top square wave is achieved.
- Repeat for the second probe if using both channels.

A correctly compensated probe displays a clean square wave. Adjust the probe's trimmer if the waveform shows overshoot or undershoot.
5. Operating Instructions
5.1 Cuntrolli basi
- Pulsante di putenza: Located on the front panel, used to turn the device on or off.
- Manopola multiuso: Used for menu navigation and parameter adjustment. Press to confirm selections.
- Cuntrolli Verticali (CH1, CH2): Adjust vertical position and scale (volts/division) for each channel. "Push to Zero" resets position, "Push to Fine" enables fine adjustment.
- Cuntrolli Orizzuntali: Adjust horizontal position and time base (seconds/division). "Push to Zero" resets position, "Push to Zoom" enables horizontal zoom.
- Cuntrolli di u grillettu: Set the trigger level, mode (Auto, Normal, Single), and force a trigger event.
- Pulsante Auto: Automatically adjusts vertical, horizontal, and trigger settings to display a stable waveform.
- Buttone Eseguisce/Stop: Starts or stops waveform acquisition.
5.2 Waveform Acquisition and Display
The UPO1102 features a 7-inch display and Ultra Phosphor technology for clear waveform visualization, even with complex signals.

Figure 5.1: Ultra Phosphor Display
Ultra Phosphor technology provides a gradient display, where brighter areas indicate more frequent occurrences of the waveform, helping to visualize signal anomalies and variations.

Figure 5.2: Multi-Channel Waveform Display
The UPO1102 can display and analyze two channels simultaneously, allowing for comparison of different signals.
5.3 Funzioni di misurazione
- Misurazione di u cursore: Activate the "Cursor" function to measure time and voltage parameters within a specified area on CH1, CH2, MATH, or REF waveforms.
- Analisi FFT: The UPO1102 features 1Mpts FFT sampling points, enabling frequency domain analysis. Access the FFT function to set frequency range, detection mode, and spectrum marking.
- Navigation Functions: Utilize time navigation, marker navigation, and segment navigation for detailed waveform inspection.

The FFT function transforms time-domain signals into the frequency domain, useful for analyzing harmonic content and noise.
5.4 Digital Decoding
The innovative hardware decoding feature allows for real-time decoding of serial bus protocols. With a deep storage of 56 Mpts, decoding speed is maintained at millisecond levels, preventing delays when viewing decoded data. This function does not affect the waveform refresh rate, maintaining the digital fluorescence display effect.
