Diagnose circuits with the Fnirsi 2D15P dual-channel oscilloscope, true RMS multimeter, and signal generator. Solve faults faster.
You receive a compact lab bench that replaces three separate tools. The 4.3-inch capacitive panel renders signals in vivid detail. Physical knobs sit within thumb reach so you adjust gain and timing without hunting menus. Live math overlays calculate differences or averages instantly while built-in parameters track peak-to-peak value and frequency.
This instrument merges a high-bandwidth oscilloscope, a true RMS multimeter, and a standalone function generator. It serves hardware testers, repair technicians, and design engineers who need rapid diagnostics anywhere.
Catch fleeting anomalies because adjustable persistence freezes weak traces for careful study.
Measure power rails accurately across wide ranges without swapping leads or recalibrating.
Outputs nine clean waveform shapes up to 10 MHz for loop testing.
Switch between dot, vector, and color temperature rendering for better glare control.
Lock onto repetitive patterns using auto or normal trigger modes.
Analog bandwidth delivers 100 MHz on one channel and 50 MHz per channel when both run together.
Display area measures 4.3 inches with 128-level grayscale contrast.
Internals house a 5000 mAh lithium cell for untethered use.
2D15P main unit.
Two P6100 passive probes.
One multimeter test lead.
One alligator clip ground lead.
USB-A to Type-C charging cord.
Attach probes to your test nodes and press the power button.
Turn the vertical and horizontal dials until the trace centers cleanly.
Spares setup guesswork by letting the scope auto-adjust threshold levels.
Build confidence since voltage, current, resistance, and capacitance checks sit alongside the visual display.
Validating microcontroller clock lines and reset pulses.
Checking ripple on switching power supplies.
Testing amplifier feedback stability before soldering.
Field engineers carrying lightweight diagnostic gear.
Makers expanding beyond basic DMM limitations.
Students analyzing analog and digital waveforms hands-on.
Does this store fading signals? Yes. Adjustable persistence runs from milliseconds to infinity, freezing erratic spikes so you can analyze them calmly.
Can I send test patterns directly? Absolutely. The internal function generator outputs nine clean waveforms up to 10 MHz with adjustable amplitude and duty cycle.
Is the interface touch driven? You navigate menus via a fluid panel paired with tactile rotary dials.
How many input channels exist? Two independent analog inputs share a combined bandwidth ceiling.
What covers standard repair work? Voltage reads up to 1000 V DC, resistance spans nearly 20 MΩ, and capacitance tracks values up to 99.99 mF.
