If you want to have an oscilloscope but don’t have a large budget, this unit is for you. It’s cheaper compared to other models, but it has all the features you need to tackle basic electrical tasks. It comes with a 1 MHz analog bandwidth, a 10 MHz maximum sample rate, and an 8K sample memory depth. The unit is only 11mm thick and weighs less than 10 ounces, so you can easily put it in your bag and bring it with you wherever you go.
4. Xminilab Portable Handheld Pocket Oscilloscope
- Mixed Signal Oscilloscope: Simultaneous sampling of analog and digital signals
- Arbitrary Waveform Generator with Sweep on all parameters
- Spectrum Analyzer with different windowing options and selectable vertical log
- Protocol Sniffer: UART, I2C, SPI
- USB connectivity: Windows, Linux, MAC, Android
This unit is actually a pocket oscilloscope, a waveform generator and a protocol sniffer all in one compact package. It’s a mixed signal oscilloscope, so it can sample analog and digital signals at the same time. It comes with a curve tracer function, a wide range of display options (including persistence and various grid options), vertical and horizontal cursors, and a spectrum analyzer with windowing options.
5. Fluke 190-202/AM/S 2 Channel LCD Color ScopeMeter Oscilloscope
- Handheld unit combines a two-channel digital oscilloscope for viewing electrical signals with a digital multimeter for measuring voltage and resistance
- Real-time sample rate is 625Ms/s for 60MHz models, 1.25GS/s for 100MHz models, 2.5GS/s for 200MHz models, and 5GS/s for 500MHz models, and record length is 10,000 points per channel for acquiring detailed waveforms
- Zoom function, three math functions plus FFT, and automatic and cursor measurements for analyzing waveforms
- 6" color LCD shows up to four readings or waveforms simultaneously
- Meets EN and IEC 61010-1:2001 and 61010-031:2002+A1:2008, ANSI/ISA 61010-1 (82.02.01), and CAN/CSA C22.2 61010-1-04 safety standards, and is rated CAT III installations to 1,000V and CAT IV installations to 600V
Even if it’s more expensive than other units, the 190-202/AM/S is worth every penny you spend. It’s a combination of a digital oscilloscope and a digital multimeter and comes with a zoom function, automatic and cursor measurements, and three math functions with FFT. It also has a 6-inch color LCD that lets you view up to four readings at the same time. The 190-202/AM/S is available in several bandwidth measurements (60 MHz, 100 MHz, 200 MHz, and 50 MHz), so you can choose the right model for you.
