4. Setup

4.1 Unpacking and Inspection

Figure 4.1: Package contents.

Carefully unpack the oscilloscope and all accessories. Verify that all items listed in the packing list are present and undamaged. The standard package includes the SDS5052E oscilloscope unit, two passive probes, a power cord, a USB cable, and a quick guide/CD.

4.2 Power Connection

1. Ensure the oscilloscope's power switch is in the OFF position.
2. Connect the provided power cord to the AC power input on the rear panel of the oscilloscope.
3. Plug the other end of the power cord into a grounded AC power outlet.

4.3 Probe Connection and Compensation

1. Connect the BNC connector of a passive probe to either the CH1 or CH2 input on the front panel.
2. Attach the probe tip to the probe compensation test point (usually a small metal loop or pin labeled "PROBE COMP" or similar) on the front panel.
3. Connect the probe's ground clip to the ground terminal next to the probe compensation test point.
4. Power on the oscilloscope.
5. Press the Autoset button. A square wave should appear on the screen.
6. Adjust the compensation screw on the probe body using a non-metallic tool until the square wave corners are flat (neither overshot nor undershot).

5. Operating Instructions

5.1 Basic Measurements

• Vertical Controls: Use the VOLTS/DIV knob for the selected channel (CH1 or CH2) to adjust the vertical scale (voltage per division). Use the VERTICAL POSITION knob to move the waveform up or down.
• Horizontal Controls: Use the SEC/DIV knob to adjust the horizontal scale (time per division). Use the HORIZONTAL POSITION knob to move the waveform left or right.
• Autoset: Press the Autoset button to automatically adjust the vertical, horizontal, and trigger settings to display a stable waveform.

5.2 Triggering

Triggering stabilizes repetitive waveforms. The SDS5052E supports Edge, Pulse, Video, and Slope trigger types.

1. Press the MENU button in the Trigger section to access trigger settings.
2. Select the desired trigger type (e.g., Edge).
3. Adjust the TRIG LEVEL knob to set the voltage level at which the trigger occurs. The trigger level indicator on the screen will move accordingly.
4. Use the 50% button for quick adjustment to the 50% level of the waveform.

5.3 Measurement Functions

The oscilloscope provides automatic measurement functions.

• Press the Measure button to display the measurement menu.
• Use the function buttons (F1-F5) to select and add/remove desired measurements (e.g., Vpp, Vmax, Frequency, Period).
• The results will be displayed on the screen.

5.4 Saving Data

Waveforms and settings can be saved to internal memory or a USB flash drive.

1. Insert a USB flash drive into the USB host port on the side panel (if saving externally).
2. Press the Save button.
3. Select the save type (e.g., Waveform, Setup, Image) and destination using the menu options.
4. Confirm the save operation.

6. Maintenance

6.1 Cleaning

To clean the instrument, disconnect it from all power sources and wipe the exterior surfaces with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these may damage the casing or display. Ensure no moisture enters the ventilation openings.

6.2 Storage

When not in use for extended periods, store the oscilloscope in a clean, dry environment, protected from extreme temperatures and humidity. It is recommended to keep the original packaging for safe storage and transport.

6.3 Calibration

The oscilloscope is factory calibrated. For continued accuracy, periodic calibration by qualified service personnel is recommended, especially after significant temperature changes or prolonged use.
