Fluke 123B Reviewed

Oscilloscopes have become an integral part of all sorts of industries, from the telecommunication and automotive ones to medicine and engineering industries.

Their various functions, including the display and analysis of electronic signals, have made work much easier.

Digital oscilloscopes are widely used nowadays rather than the analog ones, for they are far more efficient. One such oscilloscope is the Fluke 123B.

This is a very reliable product used in industries all over for various purposes. So, without further ado, let us take a look at the Fluke 123B review below!



Fluke corporations is a company founded by John Fluke in 1948. Their products are very reliable, as is evidenced by their global popularity. The Fluke 123B oscilloscope is another one of their efficient and convenient to use products.

It can be used to install and maintain electronic equipment, including industrial ones. Troubleshooting and maintaining both electrical and electro-mechanical equipment can also be done quite easily.

The plus point is that there is no need for any sort of manual adjustments for measurements, which saves a lot of time.

As for technology, it is not behind! Fluke has a mobile app called “Fluke Connect” and a software called “FlukeView software”.

These can be used to improve the performance by allowing better data analysis, archiving of information, and overall improved collaboration.

And as a result of these functions, sending data to smartphones is easy. Another convenient technology happens to be “Fluke Cloud”, which can be used to store information for later use.

For Windows users, the Fluke 123B can be used with “FlukeView” and “Scopemeter” software.
All these features are even better due to the clear screen, as well as the compactness of the device.

If you are wondering about multimeters, it has 2 of them, each 5000-count True RMS digital ones. The oscilloscope itself happens to be digital and of 20 MHz bandwidth.

This device also comes with recorder Event Detect, which enables intermittent signals of up to 4 kHz to be captured.

All these options and features require some getting used to. So, some time might be required for the learning curve.

Another thing to bear in mind would be that the Fluke 123B does not come with an amp clamp, so that has to be bought separately. Overall, this is a great product, even if a bit on the expensive side.
