I was looking for a decent handheld oscilloscope/meter and eventually ended up buying the UT81B from Uni-Trend. There isn’t much information available about this model so I decided to do a small review of it.
Let’s start with some basic specifications from the manufacturer:
- 8MHz bandwidth
- 40MS/s sample rate
- adjustable trigger (level and slope) with single-shot mode
- voltage, current, resistance, capacitance and frequency measurement
- 10 screen memory
- 160×160 monochrome display with backlight
- USB connection
Specs seem quite good for a handheld device and it should accurately display signals up to 4MHz. Time to check it out!
