2. Opsætning og indledende konfiguration
2.1 Udpakning og inspektion
Carefully remove the oscilloscope from its packaging. Inspect the unit for any signs of physical damage that may have occurred during transit. Retain the original packaging for future transportation or storage.
2.2 Strømtilslutning
- Ensure the oscilloscope's power switch is in the OFF position.
- Connect the provided power cord to the AC input on the rear panel of the oscilloscope.
- Sæt den anden ende af netledningen i en jordet stikkontakt.
2.3 Indledende tænding
Press the power button located on the front panel. The oscilloscope will perform a self-test and boot up. The display will show the Tektronix logo followed by the main measurement interface.
2.4 Connecting Probes and Inputs
The MSO44 features FlexChannels, which can be configured as analog or digital inputs.
- For analog signals, connect BNC probes to the input connectors on the front panel.
- For digital signals, use the appropriate digital probe accessories (sold separately) and connect them to the dedicated digital input ports.
- Ensure all connections are secure to prevent signal degradation.
3. Betjeningsvejledning
3.1 Brugergrænseflade overview
The oscilloscope features a 13.3-inch HD capacitive touchscreen display for intuitive operation. Key controls are also available via physical knobs and buttons on the right side of the display.
3.2 Grundlæggende målinger
- Kanalopsætning: Press the channel button corresponding to the input you wish to configure. Use the touchscreen or vertical scale knob to adjust vertical sensitivity (Volts/Div).
- Tidsbase: Use the horizontal scale knob to adjust the time base (Seconds/Div) to view det ønskede antal cyklusser.
- Udløser: The trigger system stabilizes repetitive waveforms. Use the trigger level knob to set the trigger threshold. Select trigger type (Edge, Pulse, Runt, etc.) from the trigger menu on the screen.
- Mål: Access the 'Measure' menu to add automatic measurements such as frequency, peak-to-peak voltage, RMS, etc.
3.3 Avancerede funktioner
- FlexChannel Technology: Each FlexChannel input can be configured as one analog channel or eight digital logic channels. This is configured through the channel setup menu.
- High Resolution Mode: The oscilloscope offers 12-bit ADC resolution, which can be enhanced to 16 bits in High Resolution Mode for more precise measurements. Enable this mode via the display settings.
- Optagelseslængde: The MSO44 features a 31.25 M record length, allowing for capture of long signal durations at high sample rates. Adjust record length settings in the acquisition menu.
- Analysis Tools: Utilize built-in analysis tools such as FFT (Fast Fourier Transform) for frequency domain analysis, cursors for precise point measurements, and waveform math functions.
4. Vedligeholdelse
4.1 Rengøring af instrumentet
To maintain the performance and appearance of your oscilloscope:
- Ydre: Brug en blød, damp en klud med et mildt rengøringsmiddel til at rengøre de udvendige overflader. Undgå slibende rengøringsmidler eller opløsningsmidler.
- Vise: Use a soft, lint-free cloth specifically designed for cleaning electronic displays. Do not spray cleaning solutions directly onto the screen.
- Forbindelser: Keep input connectors clean and free of dust. Use compressed air if necessary, but avoid inserting objects into the connectors.
4.2 Kalibrering
The MSO44 is factory calibrated. For optimal performance, periodic calibration by a qualified service center is recommended. Refer to the Tektronix webwebsted eller kontakt support for kalibreringstjenester.
4.3 Opbevaring
When not in use for extended periods, store the oscilloscope in a clean, dry environment, away from direct sunlight and extreme temperatures. Use the original packaging or a suitable protective case.
