The FNIRSI DSO153 mini oscilloscope combines the functions of a pocket measuring instrument and signal generator in a lightweight, easily portable design. It can analyze various waveforms, including mains voltage, pulse signals, and signals from switching power supplies. The waveform stop, zoom, and pan functions make it easier to inspect signals in detail and locate interference.
The device supports automatic, normal, and single trigger modes and offers automatic parameter adjustment. The generator provides 14 waveform types with a frequency of 0 to 10 kHz, an adjustable duty cycle of 0 to 100%, and an amplitude of 0.1 to 3 V. A 1 kHz calibration square wave signal is also available.
The built-in 1,000 mAh battery enables convenient use without constant access to a power supply. The sophisticated controls are complemented by a fold-out stand with a 90° angle, responsive buttons, a USB-C port for charging and software updates, and an automatic shutdown function to save energy.
