5. Setup

5.1 Unpacking and Inspection

Carefully remove the oscilloscope and all accessories from the packaging. Inspect the instrument for any signs of damage during transit. If any damage is found, contact your dealer or SIGLENT customer service immediately.

5.2 Connecting Power

1. Ensure the power switch on the front panel is in the OFF (O) position.
2. Connect the provided power cable to the AC power input on the rear panel of the oscilloscope.
3. Plug the other end of the power cable into a grounded AC power outlet.

5.3 Probe Connection and Compensation

1. Connect the probe to one of the analog input channels (CH1 or CH2) on the front panel.
2. Attach the probe's ground clip to the ground terminal.
3. Connect the probe tip to the probe compensation output terminal (usually a square wave test point).
4. Power on the oscilloscope.
5. Adjust the probe compensation trimmer until a flat-top square wave is displayed on the screen.

6.2 Acquiring Waveforms

1. Connect Signal: Connect your signal source to the desired input channel (e.g., CH1).
2. Auto Setup: Press the Auto Setup button for automatic scaling and triggering.
3. Manual Adjustment: Use the vertical (VOLTS/DIV) and horizontal (SEC/DIV) knobs to adjust the waveform's amplitude and time base. Use the position knobs to move the waveform vertically or horizontally.

6.3 Triggering

The trigger system stabilizes repetitive waveforms and captures single-shot events.

• Trigger Mode: Press the Trigger button to access trigger settings. Common modes include Edge, Pulse, and Video.
• Trigger Level: Adjust the trigger level knob to set the voltage threshold at which the trigger occurs.
• Trigger Source: Select the channel or external source that will trigger the acquisition.

6.4 Measurements and Analysis

The oscilloscope provides various automatic measurements and analysis functions.

• Measure: Press the Measure button to display automatic measurements like Vpp, Vmax, Frequency, Period, etc.
• Math Functions: Access functions like Add, Subtract, Multiply, Divide, FFT (Fast Fourier Transform) for advanced waveform analysis.
• History Mode: Record and review past waveforms.
• Serial Decoding (Optional): Decode various serial bus protocols like I2C, SPI, UART, CAN, LIN.
• Power Analysis (Optional): Perform detailed power measurements.
