Portable 3-in-1 instrument combining a 2-channel digital oscilloscope, TRMS multimeter and DDS function generator, intended for diagnostics, maintenance, laboratory work, training and electronic development.
The oscilloscope provides 50 MHz analogue bandwidth and 250 MSa/s real-time sampling, with two input channels, 8-bit vertical resolution, capture depth up to 64 kByte, a 10 ns/div to 10 s/div timebase and 10 mV/div to 10 V/div vertical sensitivity. Inputs support AC/DC coupling, 1×/10× probes and a 20 MHz bandwidth limit.
For signal analysis it provides Auto, Normal and Single triggering on rising or falling edges, Y-T, X-Y and roll display modes, cursors, persistence and mathematical operations between channels. FFT and automatic measurements include period, frequency, peak-to-peak, maximum, minimum, average, RMS, amplitude, duty cycle and pulse width.
Oscilloscope screenshots can be saved in BMP format for later review. USB sharing allows the instrument to appear as a storage drive on a computer for accessing screenshots and performing firmware updates.
The multimeter provides 4½ digits and 19,999 counts with TRMS measurement. It measures AC/DC voltage and current, resistance, capacitance and temperature, with diode and continuity tests. Auto mode recognises voltage and resistance and automatically distinguishes AC from DC voltage.
The built-in DDS generator provides 12 waveforms. Sine output reaches 10 MHz and the other waveform types up to 5 MHz, with 1 Hz frequency steps. Amplitude is adjustable from 0.1 to 3.0 V and square-wave duty cycle from 0 to 100%.
A 4.3-inch 480 × 272 colour IPS touchscreen provides adjustable brightness. The instrument measures approximately 145 × 98 × 35 mm, weighs about 360 g and offers an eight-language interface.
A built-in 4,000 mAh lithium battery is charged through USB-C at 5 V / 2 A. The manufacturer states up to approximately 4 h of operation. Charging should use an independent supply rather than power or USB from the equipment being tested.
The two oscilloscope channels share a common ground. When both channels are used, the two probe ground clips must be at the same potential and must not be connected to different potentials. The manual states a maximum of ±400 V at the oscilloscope input but does not declare a CAT measurement category, so this figure must not be interpreted as a mains-installation safety rating.
