5. Setup

5.1 Simba Connection

  1. Connect the supplied power lead to the power input on the rear panel of the oscilloscope.
  2. Plug the other end of the power lead into a grounded AC power outlet.
  3. Press the power button on the front panel to turn on the oscilloscope.

5.2 Probe Connection

  1. Connect the BNC connector of the passive probe to either Channel 1 (CH1) or Channel 2 (CH2) input on the front panel.
  2. Attach the ground clip of the probe to the circuit's ground point.
  3. Connect the probe tip to the test point in your circuit.
  4. Ensure the probe's attenuation setting (e.g., 1X or 10X) matches the setting on the oscilloscope for accurate readings.

6. Operating Instructions

6.1 Basic Operation

  • Auto Scale: Press the 'AUTO SET' button to automatically adjust vertical, horizontal, and trigger settings for a stable waveform display. This function detects sine and square waves automatically.
  • Vertical Controls (VOLTS/DIV, POSITION): Use the VOLTS/DIV knobs to adjust the vertical scale (voltage per division) for each channel. The POSITION knobs shift the waveform vertically.
  • Horizontal Controls (SEC/DIV, POSITION): Use the SEC/DIV knob to adjust the horizontal scale (time per division). The horizontal POSITION knob shifts the waveform horizontally.
  • Trigger Level: Adjust the 'TRIGGER LEVEL' knob to set the voltage level at which the oscilloscope captures a waveform.

6.2 Yepamusoro Mabasa

  • Waveform jenareta: Access the waveform generator menu to select and configure output waveforms such as Sine, Square, Ramp, Exponential, Noise, and DC. Connect the 'WAVE GEN' output to your circuit.
  • Trigger Modes: Utilize the 14 available trigger modes (Edge, Pulse, Video, Slope, Overtime, Window, Pattern, Interval, Under Amp, UART, LIN, CAN, SPI, IIC) to capture specific events. Select modes via the 'TRIGGER' menu.
  • Serial Protocol Decoding: The oscilloscope supports decoding for RS232/UART, I2C, SPI, CAN, and LIN protocols. Configure these settings in the 'DECODE' menu to view decoded data.
  • Zviyero: The device offers 32 types of automatic measurements with real-time statistics (maximum, minimum, standard deviation, etc.). Access these via the 'MEASURE' menu.
  • USB Kubatana: Connect a USB thumb drive to the USB Host port to save oscilloscope setups, waveforms, reference waveforms, CSV files, and images. The USB Device port allows for remote control from a computer using SCPI commands.

7. Kuchengeta

7.1 Kuchenesa

To clean the instrument, use a soft cloth dampened with a mild detergent solution. Do not use abrasive cleaners or solvents that could damage the casing or screen. Ensure the device is powered off and unplugged before cleaning.

7.2 Kuchengeta

When not in use, store the oscilloscope in a dry, dust-free environment away from direct sunlight and extreme temperatures. Use the original packaging or a suitable case for protection during transport.
