It combines essential measurement features with compact form factor and straightforward connectivity for probes and triggers. The device delivers sufficient timebase and amplitude control for routine diagnostics and basic lab experiments while keeping operation accessible for technicians, students and hobbyists.

Suitable for

• Repair and maintenance of consumer electronics and small appliances
• Educational laboratories and electronics training courses
• Troubleshooting prototypes and printed circuit boards
• Basic signal verification and timing analysis in development workflows

Key specifications

• Channels: 2 analog input channels
• Display: built-in graphical display for waveform visualization
• Input type: standard oscilloscope probe inputs compatible with passive probes
• Timebase: adjustable time/div range suitable for general-purpose measurements
• Trigger: manual and auto trigger modes for capturing repetitive and single-shot signals
• Measurements: basic amplitude and timing measurement functions (peak, RMS, frequency, period)
• Controls: front-panel knobs and buttons for vertical, horizontal and trigger adjustments
• Form factor: benchtop design suitable for laboratory and repair-bench placement

How to use

Connect a passive probe to the desired input channel and attach the probe tip and ground clip to the test points on the circuit under investigation. Power on the oscilloscope and set appropriate vertical sensitivity and timebase values to center the waveform on the display. Use the trigger controls to obtain a stable waveform display; select edge trigger and adjust level and slope as needed. Use cursors or built-in measurement functions to read amplitude and time parameters. For two-channel comparisons, synchronize channel settings and use math or reference functions if available to analyze relationships between signals.

Usage recommendations

Ensure proper grounding of the probe and the device under test to avoid ground loops or measurement errors. Start with higher probe attenuation and lower vertical gain when probing unknown signals, then refine settings to improve resolution. If measuring fast or high-amplitude signals, confirm probe bandwidth and ratings to protect the instrument and obtain accurate results.
