Quick Summary
The BSIDE O9 is a handheld automotive oscilloscope and multimeter with 2 channels, 50MHz bandwidth, a 250MSa/s real time sampling rate, and a 3.98in full view display. It is designed for checking signals, measuring electrical values, and supporting higher current testing with a Rogowski coil terminal for up to 2000A AC current.
Who It Is Best For
This is a practical choice for users who want one portable tool for oscilloscope work and multimeter measurements in the same unit. It suits people who need to inspect waveforms, use a signal generator, or take electrical readings on a handheld device with a readable screen.
What To Know Before You Buy
The O9 combines oscilloscope, multimeter, and signal generator functions, so it is aimed at users who want a multi function tester rather than a single purpose meter. The display is described as a colour TFT screen and waveforms can be saved for viewing on the unit or on a PC.
Pros: Combines multiple test functions in one handheld unit and includes a large display for easier viewing.
Cons: Check the selected measurement range and accessory setup before ordering to make sure it matches your intended use.
