5. Configuració
- Connexió d'alimentació: Connect the provided power cord to the AC input on the rear panel and then to a suitable power outlet.
- Encès: Premeu el botó d'engegada del panell frontal per encendre l'oscil·loscopi.
- Connexió de la sonda: Connect the passive probes to the desired input channels (CH1, CH2, CH3, CH4) on the front panel.
- Compensació de la sonda:
Before taking measurements, it is crucial to compensate the probes to ensure accurate readings. Connect the probe tip to the probe compensation output (usually a square wave signal) on the front panel and the ground clip to the ground terminal. Adjust the compensation trimmer on the probe until a flat-top square wave is displayed on the screen.
6. Instruccions de funcionament
6.1 Mesures bàsiques
To perform basic voltage and time measurements:
- Configuració automàtica: Premeu el botó Configuració automàtica button to automatically adjust the vertical, horizontal, and trigger settings for a stable waveform display.
- Controls verticals: Use the vertical position and scale knobs for each channel to adjust the waveform's vertical position and ampla latitud.
- Controls horitzontals: Use the horizontal position and scale knobs to adjust the waveform's horizontal position and time base.
- Measure Function: Premeu el botó Mesura button to access automatic measurement parameters such as Vpp, Vmax, Vmin, Frequency, Period, etc.
6.2 Funcions avançades
- SPO Technology: The Super Phosphor Oscilloscope (SPO) technology provides a high waveform capture rate of 400,000 frames/sec (sequence mode), allowing for the capture of infrequent events.
- Funció FFT: Utilize the 128k point FFT math function for high-frequency resolution when analyzing signal spectra. Access this via the Matemàtiques menú.
