✔ Signal simulation for testing devices
Example scenario:
A technician generates a 1kHz sine wave to test an amplifier input while simultaneously measuring the circuit voltage and capturing the waveform for later review.
5️⃣ How to Use the Device (Step-by-Step)
Step 1 — Power On
Recharge the device if needed and press the power button.
Step 2 — Select Mode
Choose between oscilloscope, multimeter, or waveform generator using the mode selection button.
Step 3 — Connect Probes / Leads
Oscilloscope probes to test points; ground clip to circuit ground
Multimeter leads to appropriate terminals (COM and V/Ω/A)
Waveform output to device under test
Step 4 — Adjust Settings
Oscilloscope: volts/div, time/div, and trigger type/level
Multimeter: measurement type (V, A, Ω) and range
Waveform Generator: frequency, amplitude, and waveform type
Step 5 — Observe or Output Signals
Oscilloscope: monitor waveforms on display
Multimeter: observe voltage/current/resistance
Waveform Generator: output test waveform to circuit
Step 6 — Store Data
Press memory button to save waveform or measurement data for later analysis.
Step 7 — Recharge Battery
Use USB port to recharge when battery is low.
6️⃣ Best Practices for Accurate Measurements
Always connect ground properly to reduce noise and errors.
Use short probe leads for oscilloscope measurements.
Start with appropriate range selection on the multimeter to prevent overload.
Store important waveform or measurement data frequently.
Avoid strong electromagnetic interference during measurements.
Keep battery charged for consistent performance.
