Before You Begin

• Inspect the scope:

  • Ensure probes are in good condition

  • Verify probe attenuation (1× / 10×) matches the scope setting

  • Check that the BNC connectors are clean

• Set up your workspace:

  • Keep wires tidy

  • Avoid running high‑voltage circuits near the scope

• Select the correct input impedance:

  • 1 MΩ
    for general electronics

  • 50 Ω
    for RF or fast digital signals

Operating Guidelines

Basic Setup

• Connect probe to Channel 1 or Channel 2

• Set Volts/Div to frame the signal

• Set Time/Div to capture the desired window

• Use Auto‑Scale if you’re unsure where the signal is

Triggering

• Choose trigger source (CH1, CH2, external)

• Set trigger type:

  • Edge
    for most signals

  • Pulse width
    for glitch detection

  • TV
    for composite video signals

• Adjust trigger level until waveform stabilizes

Peak Detect Mode

• Use peak detect to capture:

  • Fast spikes

  • Narrow glitches

  • Transients that normal sampling might miss

• Peak detect is ideal for digital logic anomalies

Storage & Measurement

• Use storage mode to:

  • Freeze waveforms

  • Compare signals

  • Capture one‑shot events

• Built‑in measurement tools include:

  • Frequency

  • Period

  • Peak‑to‑peak

  • RMS

  • Rise/fall time

  • Duty cycle

Supported Use Cases

Approved:

• Microcontroller debugging

• Logic signal analysis

• RF up to 500 MHz

• High‑speed digital edges

• Analog circuit troubleshooting

• Power electronics (low‑voltage)

• Audio and waveform analysis

Not approved:

• Mains AC probing

• High‑voltage circuits

Care & Etiquette

• Always use proper oscilloscope probes

• Do not yank BNC connectors

• Avoid touching the CRT screen with tools

• Return probes to holders after use

• Report:

  • Dim CRT

  • Trigger instability

  • Noisy fan

  • Input channel issues

Common Issues & Troubleshooting

• Waveform drifting

  • Adjust trigger level or mode

• Signal clipped

  • Reduce Volts/Div or check probe attenuation

• No signal

  • Wrong input impedance or coupling

• Glitches not visible

  • Enable peak detect

• Aliasing

  • Increase sample rate or reduce Time/Div
