2. Installation et configuration initiale

2.1 Déballage et inspection

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 Connexion d'alimentation

1. Ensure the oscilloscope's power switch is in the OFF position.
2. Connect the provided power cord to the AC input on the rear panel of the oscilloscope.
3. Branchez l'autre extrémité du cordon d'alimentation dans une prise de courant alternatif mise à la terre.

2.3 Mise sous tension initiale

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. Mode d'emploi

3.1 Interface utilisateur terminéeview

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 Mesures de base

1. Configuration des chaînes : 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).
2. Base de temps: Use the horizontal scale knob to adjust the time base (Seconds/Div) to view the desired number of cycles.
3. Déclenchement : 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.
4. Mesures: Access the 'Measure' menu to add automatic measurements such as frequency, peak-to-peak voltage, RMS, etc.

3.3 fonctionnalités avancées

• 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.
• Mode haute résolution : 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.
• Durée d'enregistrement : 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.
• Outils d'analyse : 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. Entretien

4.1 Nettoyage de l'appareil

To maintain the performance and appearance of your oscilloscope:

• Extérieur: Utilisez un chiffon doux et sec.amp cloth with a mild detergent to clean the exterior surfaces. Avoid abrasive cleaners or solvents.
