Handheld 3-in-1 Test Instrument

The WUQ DSO-TC3 combines a digital oscilloscope, a DDS signal generator and a transistor tester in a single handheld unit. A 2.4 inch TFT display shows captured waveforms and measurement results. The oscilloscope section provides 500 kHz bandwidth with a 10 MS/s sampling rate for periodic analog and aperiodic digital signals. One-key AUTO sets up the display without manual adjustments.

Integrated Accessories Expand Measurement Modes

Supplied test leads and probes enable six waveform outputs including sine, square, pulse, triangle, ramp and DC for circuit stimulation. The transistor tester identifies NPN and PNP bipolar types plus N-channel and P-channel MOSFETs with automatic pin detection. Additional modes cover continuity testing, 0-40 V voltage measurement, PWM output, 0-32 V regulated diode checks, DS18B20 temperature and DHT11 humidity sensing. A rechargeable lithium battery powers all functions for portable use.

Verify Signal Requirements Before Ordering

The 500 kHz bandwidth and 10 MS/s sampling rate suit low-frequency analogue and digital signals but will not capture higher-speed buses or fast transients. Maximum input voltage is 40 V so circuits exceeding this level need external attenuation. Signal generator amplitude and offset ranges are fixed by the hardware and cannot be extended. Ensure the measurement tasks you plan fall within these limits.

Questions about this item

Will the 2.4 inch TFT display or rechargeable lithium battery need replacing first?

The rechargeable lithium battery will likely need replacement before the 2.4 inch TFT display as batteries degrade with charge cycles while the display has no moving parts.

What measurement limit will I reach first during continuous testing with the 10 MS/s sampling rate?

The 500 kHz bandwidth limit will be reached first as signals above this frequency cannot be accurately captured regardless of the 10 MS/s sampling rate.

How much heat does the unit generate when running the DDS signal generator at 32 V regulated output all day?

The 32 V regulated diode measurement mode and signal generator functions are low-power operations that produce minimal heat during extended use.
