5. Setup

Follow these steps for initial setup of your oscilloscope.

1. Connect Power: Connect the provided power cord to the AC input on the rear panel of the oscilloscope and then to a grounded power outlet.
2. Power On: Press the power button located on the front panel to turn on the instrument. The Rigol logo will appear on the screen during startup.
3. Connect Probes:
   • Attach the BNC connector of a passive probe to one of the input channels (CH1 or CH2) on the front panel.
   • Connect the probe ground clip to the ground terminal on the oscilloscope or to the ground of the circuit under test.
   • Set the attenuation switch on the probe (e.g., 1x or 10x) to match the setting on the oscilloscope channel menu. For most measurements, 10x is recommended.
4. Probe Compensation: For accurate measurements, compensate the probes. Connect the probe tip to the probe compensation signal output (usually a square wave) on the front panel and adjust the probe's compensation trimmer until a flat-top square wave is displayed.

6. Operating the Oscilloscope

This section covers basic operation for common measurement tasks.

6.1 Basic Measurements

• Vertical Scale (Volts/Div): Use the vertical scale knob for the selected channel (CH1 or CH2) to adjust the voltage per division.
• Vertical Position: Use the vertical position knob to move the waveform up or down on the screen.
• Horizontal Scale (Time/Div): Use the horizontal scale knob to adjust the time per division, controlling the time window displayed.
• Horizontal Position: Use the horizontal position knob to shift the waveform left or right.

6.2 Triggering

Triggering stabilizes repetitive waveforms and captures single-shot events.

• Trigger Level: Adjust the trigger level knob to set the voltage point at which the oscilloscope triggers.
• Trigger Mode: Press the MODE button in the Trigger section to select trigger modes like Auto, Normal, or Single.
• Trigger Source: Select the input channel (CH1, CH2, EXT, AC Line) that will be used as the trigger source.

6.3 Measurement Functions

The DS1202Z-E offers various automatic measurement functions.

• Press the MEASURE button to access the automatic measurement menu.
• Select desired measurements such as Vpp (Peak-to-Peak Voltage), Vrms (RMS Voltage), Frequency, Period, Rise Time, etc.

6.4 Saving Data

You can save waveforms, setups, or screen images to a USB flash drive.

• Insert a USB flash drive into the USB host port on the front panel.
• Press the STORAGE button to access the save menu.
• Select the desired save type (Waveform, Setup, Image) and follow the on-screen prompts to save the data.

7. Maintenance

Proper maintenance ensures the longevity and performance of your oscilloscope.

7.1 Cleaning

• Clean the exterior of the instrument with a soft cloth dampened with mild detergent and water. Do not use abrasive cleaners or solvents.
• Ensure the instrument is powered off and disconnected from the power source before cleaning.
• Avoid spraying liquids directly onto the instrument.

7.2 Storage

• When not in use for extended periods, store the oscilloscope in a clean, dry environment.
• Protect the screen from scratches and impacts.
