Pen-shaped Compact Wireless Oscilloscopes


Oscilloscopes have been the vital instruments for testing and measurement from a very long time.  However, the innovations regarding them have been comparatively at a slower pace. The reasons could be attributed to their basic use and feasibility to lab environment. But with everything getting compact and wireless, the oscilloscope market is also seeing some new technology products stepping in.The pen-shaped oscilloscope from Ikalogic is the new addition.

Hardware description

The company has named the device IkaScope. It is shaped like a broad pen or more like a highlighter and weighs around 60 gram. When we remove the protective cap it reveals the probe tip. The probe communicates via Wi-Fi with a PC, tablet or smartphone. There is no on/off button on the rear and there are just two LED indicators and a micro USB connector for charging the built-in battery.

The carbide tip of the IkaScope also acts as a power switch for the entire device. Ikalogic has patented this under the name ‘ProbeClick’. In fact, it is simply a push button switch mounted at the other end of the probe pin.

How to use this pen oscilloscope?


We can use the IkaScope by grasping it firmly and pressing the probe tip against a point in the circuit where you want to make a measurement, causing the tip to be pushed in slightly. This switches on the IkaScope electronics, and then the pen looks for a Wi-Fi link to a PC, tablet or smartphone to deliver its measurement data. When we lift the probe tip, the scope image is frozen and saved.

Display and software

The associated measurement software is available for virtually all current types of computer –  PCs with Windows, Linux or Mac OS and tablets or smartphones with Android iOS. The user interface is virtually the same on all systems. The measured signal occupies most of the screen (window), just like other oscilloscope programs.

The usual control knobs for functions such as triggering, signal attenuation and time base are located at the side and bottom edges.

The top left corner of the screen displays connectivity with the device. The type of network to be used could also be selected from this button.The default Wi-Fi network (soft AP) is already setup which could be changed to the required home or office network. This will allow any device connected over Ethernet to access data sent from pen.
