Reliable DAQ System

DEWE-43A weighs under two pounds and is small enough to fit in your hand. And yet inside this small box beats the heart of a giant. 

When you need an instrument with stellar specifications, and yet with a budget friendly price tag, DEWE-43A will not let you down. 

But don’t get confused by a great price. The build quality is not compromised. We carefully design our instruments and CNC every unit out of a solid block of aluminum. This way, the instrument is not only tough, but also light for maximum portability.

DEWE-43A is an ideal solution for various dynamic data acquisition applications. It will help you solve most demanding test and measurement challenges. It is used around the world and really proven to be a Swiss Army Knife for every test and measurement engineer.

Easy to Use DAQ

Using DEWE-43A does not require any complex configuration setups or programming.

With plug and play functionality, smart sensors, and advanced TEDS support making measurements with DEWE-43A is easier than riding a bike. You will get it right the first time and you will be ready to measure in no time.

Getting precise and graphically rich results is as easy as ever. Just drag and drop one of the many flexible visual displays and connect them to your channels. Voila! It works like magic.

Precise Counter and Encoder Measurement

DEWE-43A utilizes our patented technology called SUPERCOUNTERS® in every of its eight counter/encoder inputs. 

Counter inputs can measure RPM and angle of rotating machines. In comparison to standard counters, which only output integer numbers one sample later (e.g. 1, 1, 2, 2, 3, 4), SUPERCOUNTERs® are able to extract the accurate values like 1.37, 1.87, 2.37, etc. fully synchronized for time and amplitude. This is done by measuring the exact time of the rising edge of the signal with an additional counter. Our SUPERCOUNTERs® work on a 102.4 MHz time base, independent from the current sampling rate.

Counter inputs are fully synchronized with analog and CAN bus data and enable easy applications like balancing, order tracking and torsional vibrations.


DEWE-43A data acquisition hardware is capable to acquire different signals like analog, CAN, counter, encoder, and digital. With the power of included Dewesoft X3 software, you can easily acquire and combine data from additional interfaces like GPS, Flexray, Ethernet, Serial, PCM telemetry, and many more. 

Even though each data source can have different sampling rates, all your data will be perfectly synchronized down to microsecond accuracy. All this thanks to our timing and GPS syncronization technologies. 

Synchronized video can be added for free. Dewesoft includes powerful video engine and has support for simple DirectX web cameras, high speed video cameras that are fully synced to analog data, and also 3rd party thermal cameras.


If the channel count on one DEWE-43A DAQ instrument is not enough our flexible design allows you to easily extend channels at any time. 

You can either synchronize multiple DEWE-43A instruments together or extend input channel count with any of our other DAQ systems such as SIRIUS or KRYPTON, or even navigational instruments or CAN interfaces. 

The configuration for working with multiple instruments is as easy as working with single unit and thanks to synchronization technologies (internal or external IRIG, GPS) data will always be perfectly synchronized.

Award Winner

DEWE-43A received a Product of the Year award from NASA's Tech Briefs magazine.

DEWE-43A stood out from the competition of brands such as National Instruments, Autodesk, Honeywell, and others. DEWE-43A got more votes that all other contenders combined, which makes this win even more significant.
