Good measurement data postprocessing tool also for large measurement sets **Rating:** 4.5/5.0 stars **Reviewed by:** Pavol V. | Lead engineer, Enterprise (> 1000 emp.) **Reviewed Date:** September 06, 2024 **What do you like best about DIAdem?** It is good data/signal processing tool also sutable for large sizes of measurement sets. The automatization through VBA or Python can helps a lot with repeated work. There are plenty of post processing functions available. Visualisation of large data sets in graphs is also relatively fast. It has possibility of load data not only from NI LabView standards but also other industrial standards, Excel and text .csv like. **What do you dislike about DIAdem?** Scripting require higher license and is not available in Basic. **What problems is DIAdem solving and how is that benefiting you?** Measurement data analysis, automatization of analysis with significant time saving ### 2. Fantastic Tool for Data Reduction and Presentation **Rating:** 4.5/5.0 stars **Reviewed by:** Keith M. | Mechanical Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** January 18, 2022 **What do you like best about DIAdem?** As a mechanical engineer with limited programming background, I find that Diadem strikes the right balance between tools and functions available through menus and advanced tools for scripting. With little overhead, it is pretty easy to open a data file, view, process and plot. Compared to the alternatives (Excel, Matlab, Python), I find that Diadem handles large datasets as well as Matlab/Python well and has a clean and easy to use GUI like excel. I aslo find that the macro recording tools minimize the ammount of scripting needed to automate most batch processing. Overall, I find it a very usefull tool that isn't hard to pick up and mininimizes the overhead for novice programmers. **What do you dislike about DIAdem?** I would prefer more examples and help with scripting. Using VBA scripting commands that are not able to be accessed by recording macros is sometimes cumbersome and requires a fair bit of research to use correctly. Additionally, automated processing of of multiple data sets using the same script involves a bit of a learning curve and could be simplified **What problems is DIAdem solving and how is that benefiting you?** I've used Diadem for processing mechanism tests, static load tests, and shock/vibe test data. Diadem works very well for large datasets that would normally cause Excel to not respond. The integrated waterflow plot capability and rainflow analysis make quick work of otherwise challenging problems ### 3. Big batch evaluations. **Rating:** 2.5/5.0 stars **Reviewed by:** Elisabet B. | Board Member, Small-Business (50 or fewer emp.) **Reviewed Date:** January 21, 2022 **What do you like best about DIAdem?** I like the possibilities there are a lot of signal analysis and other things **What do you dislike about DIAdem?** The lack of easy ways to do batch evaluations and do the same for many channels and different files. If you should do filtering, weighting , integration and spectrum för one channel you normally want to do this for all channels in all files and the plot some of it out. This is complicated with diadem and involves a lot of programming . There are functions that can choose to process all channels and other that is not. My advice is to look at Sound and Vibration Assistant how it is solved there. **Recommendations to others considering DIAdem:** It's not a program for effective evaluation of large data files **What problems is DIAdem solving and how is that benefiting you?** I do searching for occasions where machine components av pipe systems is damaged and see if we can find the road cause ### 4. Simple and limitless but sometimes crude - DIAdem from programmers point of view **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Automotive | Enterprise (> 1000 emp.) **Reviewed Date:** January 20, 2022 **What do you like best about DIAdem?** Importing data into DIAdem by GUI is very straightforward. Inbuilt plugins and the ability to create new plugins on the run proved to be very helpfull, especially in the early stage of solving a problem. VIEWS section is exceptionally effective when analazining data. Works amazingly fast (comparing to excel) and doesnt require any coding nor commitment (comparing to MatLab). VBS is very simple to learn and introduce other people to it. It also provides pretty much limitless functionalities. In-built analytic functions have good documentation with examples of usage. Writing your own code has a comfortable level of abstraction. Many goals can be achieved by diffrent approaches. You can choose whether to trust analytic functions or write your own implementation. **What do you dislike about DIAdem?** No backward compatibility. Graphic designer for reports lacks any beautifying capabilities like aligning text boxes. Using values from channels in reports is messy. Reports are vulnerable to simple name changes. Generally, maintaining a report is more annoying than it should be. VBS in DIAdem inherits all problems of the old programming language. No reliable way of debugging the code. Very crude and low-level way of handling exceptions. The nature of global channels makes it impossible to write self-contained functions. Objets seem to be just a coding sweetener - it is usually not actually beneficial to create SOLID units of code becouse it is neither faster nor more maintainable. Maybe some of these problems are fixed when you use new python code but it only works in the newest version and I can't accept this limitation right now. **Recommendations to others considering DIAdem:** DIAdem excels when you need to analyze a lot of data or do complex evaluations. Regardless, it is effective and easy to use. I won't recommend DIAdem for simple evaluations only. I also would be hesitant if you know that the type of your data will often change unpredictably **What problems is DIAdem solving and how is that benefiting you?** I use DIAdem to analyze medium size data from measurements: looking for characteristic values, finding peeks, visualizing data, etc. By comparing results from different samples I can make claims about the product and improve the production process. ### 5. Load spectrum simulation **Rating:** 4.5/5.0 stars **Reviewed by:** Christoph B. | Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** January 19, 2022 **What do you like best about DIAdem?** The evaluation and visualization of large amounts of data works perfect **What do you dislike about DIAdem?** Analysis via view function. Unfortunately, only the size of one signal can be displayed in the graph at a time **Recommendations to others considering DIAdem:** Many good tutorials available **What problems is DIAdem solving and how is that benefiting you?** Component design through knowledge about load time cycles ### 6. DIAdem is a great, flexible data analysis tool! **Rating:** 5.0/5.0 stars **Reviewed by:** Ali R. | Engine Calibration & Development Engineer, Enterprise (> 1000 emp.) **Reviewed Date:** June 10, 2021 **What do you like best about DIAdem?** Overall, DIAdem is very flexible and user-friendly. Specifically, the View and Report tabs, as well as the Math Tools and scripting environment, are great. **What do you dislike about DIAdem?** The default color schemes of the plots! In the new DIAdem 2019, the default plot line color schemes are not good at all! It isn't easy to understand when you plot many channels with those color schemes. Also, when one loads multiple sets of data, it can get pretty overwhelming. So, maybe find better ways to streamline the user interface when one loads let's say, 20 sets of data. **What problems is DIAdem solving and how is that benefiting you?** I look at engine performance and vehicle performance data using DIAdem. I love the overall user interface and flexibility of plotting the data, applying different filters or do a simple mathematical calculation on the channels. ### 7. Great tool for analysing and presenting data! **Rating:** 4.5/5.0 stars **Reviewed by:** Vincent v. | Senior test engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** September 29, 2021 **What do you like best about DIAdem?** Efficient and quick tool for acquisition **What do you dislike about DIAdem?** Not capable of loading all data extensions **Recommendations to others considering DIAdem:** I recommend using Diadem, as it is a quick and efficient way to analyze data, present data, and report data. Also, modify data (such as units, offsets, FFT's, etc.) is an easy job now. **What problems is DIAdem solving and how is that benefiting you?** I am creating 3d graphs and colormaps to present in reports and presentations. ### 8. Feedback on DIAdem **Rating:** 4.0/5.0 stars **Reviewed by:** Nishanth T. | Technical Service in the field of Research & Development, Small-Business (50 or fewer emp.) **Reviewed Date:** June 13, 2021 **What do you like best about DIAdem?** Easily understandable giving more rooms for the research industry. I have found DIAdem can be used even without any prior knowledge. All the features and the tools can be easily understandable. There is also description for each tools, which gives the customer a confident environment. By reading the description, it is very easy to understand the usage of each and every tools. Those who wants to learn the software, can learn very quickly by watching the tutorials provided by the developer of DIAdem. I would highly recommend this to any +one who is willing to try an amazing software. **What do you dislike about DIAdem?** I really don't have any points as to say dislike. But definetely i believe that the future updates of DIAdem will bring more features and more varieties to the customers. One suggestion for the developer from my side would be to conduct more seminars or webinars on easy usage of this software. In my point of view, users could learn easily by watching a video tutorials or recorded webinars/seminars. **What problems is DIAdem solving and how is that benefiting you?** I was using DIAdem to thermomapping the sealing device and it gave the chance to map the real values. Without DIAdem it would have not possible to track the real temperature on the device. More than half of my colleague in the research institute found DIAdem as a user friendly and easy to work with. I am happy to say that DIAdem was a great part for me during my master thesis. ### 9. good analysis **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Machinery | Small-Business (50 or fewer emp.) **Reviewed Date:** February 19, 2022 **What do you like best about DIAdem?** Automation with sensory operations and scripts **What do you dislike about DIAdem?** 3d map is slow..... There is nothing else！ **What problems is DIAdem solving and how is that benefiting you?** It is used to analyze experimental data automatically. ### 10. A handy software for data analysis **Rating:** 5.0/5.0 stars **Reviewed by:** GOPINATHH R. | Associate Founder, Small-Business (50 or fewer emp.) **Reviewed Date:** January 04, 2021 **What do you like best about DIAdem?** Fourier Transform analysis and Time channel editing. The raw data is converted automatically into physical values. This is done using conversion rules from the database. This is the best thing I liked while using the software. The Graphical interface is flexible and easy to use without any programming skills & provides a universal platform for numerous applications in diverse fields **What do you dislike about DIAdem?** Little slow while handling more number of channels. I already tried using queues to transfer data, but control over memory-allocation / deallocation can't easily be done... perhaps a switch in the connector pane of subVIs saying "transfer data by pointers" could be helpful. - Data structures: I am using some C++-DLLs for data analysis. As there are sometimes some structs in the function-arguments-list, I had to write a wrapper-DLL. Perhaps there's a possibility to get this compatible... it would be nice if an array of a cluster could be converted to an array of a struct. - Speed: In some applications, I already realized that the speed of LabView can be improved by rewriting LabView-Sub-Vis into C++code. I think this is due to the LV-runtime-engine which has to "convert" the binary code of labview into native code??? Would be great if it would be possible to generate native code directly. - Expandability: It's hard to implement new functions into a already written LV-Program. By using design patterns like producer-consumer, the expandability is improved in comparison to a "normal" LV-program, but in comparison to a text-based language, LV still stands back. **Recommendations to others considering DIAdem:** Its a very nice software, handy and less memory space needed while operating this software. So, it will be helpful for new users to learn and implement faster. Very easy to learn and work. Faster to export the data from the analyzed software. So, I recommend for new users. DIAdem can be used in all phases of the development and production of vehicles, where measurement data must be analyzed, compared and presented together with the results in meaningful reports. **What problems is DIAdem solving and how is that benefiting you?** Order tracking and multi axis chart preparation is easier ## DIAdem Discussions - [Can diadem used for data mining in real time?
