Thanks for taking the time to share this.... really appreciate the insight.
Phase, speed, Bentley rack vibration and subsequent shaft orbits are a major factor in me looking for a new software to use.... the existing software that I use is seemingly never able to read a tachometer or speed data from a keyphasor. It also seems to like to "erase" spectral data depending on what location you use as a phase reference.
I did see that DIAdem looked like it would be required after looking more closely into the YouTube videos.... the initial low price kind of struck me as a "trojan horse" price if you know what I mean.
Thanks again for taking the time to provide this information.... I am going to look into the suggestions you provided for sure.

Kyle,
I would encourage you to be be very careful with the Flexlogger software. Not that it's not good. Far from it. It looks very nice. However, I have been bitten before by sample videos like this that show you a canned demonstration, and it looks like it's a perfect carryover to what you're doing. However, I'm sure you noticed the DIADEM banner that flashed during the video, around timestamp 3:50. That's an add-on package that you need to buy, IF you want to perform the tasks that he did in the video. Flex Logger

DIADEM packages
You'll also notice that he's only showing amplitude and SPEED. It's not giving him a once-per-rev signal that is linked to the data. He's getting a 1x/rev to calculate the speed, but it's just a raw signal that he's trending. It's not actually connected to the vibration signal. So you can't get phase from those inputs. If you want phase, you'll need a separate algorithm (that you'll have to build), unless they have a specific phase reference module that I'm not seeing/not aware of. This is what became problematic for me when using DASYLab. I got it working, but it was not easy or straightforward.
I might not fully appreciate the kind of data that you're collecting, or why, so I can't say that this isn't a good example of a use case for you. Just be cautious.
I was told that LabView could do everything I wanted/needed. They don't usually understand all the things that you and I need to do. They often like to highlight the metadata that can be stored with the application. Yes, it's nice, but hardly the most important piece of information that I'm looking for.
If you haven't already looked into it, you could also look at the PicoScope. It has limitations, but it's great for a portable digital oscilloscope that you can data with very quickly. Just something else to consider.

Hi Kristan,
Thank you so much for taking the time to reply and for sharing your experiences. I am already looking into the DasyLab option that you have mentioned. We do a lot of ODS/Modal Analysis projects every year and I too took a peak at the Data Acquisition option in ME Scope.... it did look a bit cumbersome but I can't say I did anything more than stare at it from 35,000 feet.
While looking at the NI website I did find a bunch of videos online about their Flexlogger software.... it doesn't look terrible and is only $793 per year. I think I may get a license for this and start to play with it some.... thank you again for taking the time to reply to this post. If this Flexlogger software pans out.... I will share my experiences in this thread.
Thank you!

Kyle,
I have been around this block too many times to count. There are several options for you, depending on what your end game is. If you want quick and easy, I would suggest DASYLab, from Measurement Computing. https://www.mccdaq.com/dasylab-index. They are another NI acquisition that they tried to kill. So far, they are limping along, but the company is going through some changes. Still, it's REALLY easy to use, and works great with NI hardware. You will need to make sure that you have NI MAX installed, because you'll need to configure the tasks for the device using MAX. Then you just load the NI modules when you're creating your data acquisition in DASYLab. The input device will use the settings (samples, frequency, etc.) when you create your acquisition model. I started with LabVIEW and found DASYLab really easy to get started with, and there's not much of a limitation for what you're doing. LabView was a total cluster, because you have to program graphically, which is a challenge if you don't already know/understand it. And, every time you want to do something, you find that there's another piece of LabView that you need, which you don't have (Yes, $$$ is required). If you want to do real time with lots of channels, you might run into some issues with DASYLab reading the data as fast as it comes in. But that's where you'd really want an Alta Solutions box, anyway.
If you want to go a step up, and you don't mind spending the time learning, you can use ME'scope, from Vibrant (www.vibetech.com). I also use this, and I'm currently fighting with it now. It has a lot more tools and capabilities than I've learned how to use, but it's still great for data acquisition using the NI-9232 or 9234 (what I'm using now for impact testing with a CTC Triax - TREA330 & PCB hammer). The acquisition set up and configuration is a bit of a challenge because there's not a lot of training or information on that piece. You want to be sure you get this right, and get the data stored properly, before you implement a solution like this. It's a great tool, but there are some things to learn, and it's not fool proof. But I would still highly recommend it, depending on what kind of data you're looking for.
If you really want to go all out, do some programming, or have someone build you a custom application around your hardware, then you could also go with Mathworks, a.k.a. Matlab. I have also dabbled with this. I like this option a LOT, but I'm not interested in being an application developer. I was able to set up the connection and collect data. There's much more power in Matlab, but you also have to either spend the money on the pre-built modules (which work well), or you have to build it yourself. Mathworks always offers support, and I'm sure you can get them to build you exactly what you want, if you don't feel like doing it yourself. I was able to teach myself and get started. But I didn't want to build a monster application that I would have to keep maintaining and repackaging as an executable. The programming side of this is what will be the biggest hurdle to overcome, but Matlab is a great option if you want to build a high-end custom application for your needs.
I would start with DASYLab. They offer a 28-day trial version so you can play with it. If you decide to buy, they just send you the license number and it activates the trial version for you.
I hope that helps.

Hi Folks,
Was looking for some help..... we use real time analyzers 90% of the time for our troubelshooting projects.....National Instruments hardware... cDaq Chassis with NI9234 and NI9232 data acquisition cards. It's small and modular.... works great for what we do. Our problem is analysis software....
I am looking for various vibration analysis softwares that we could use with this hardware. For what I know... EZ Thomas/Analyst/Balance which were used with the IOTech hardware has gone away (and was not compatible with NI Hardware).... The Alta Solutions Software looks really nice but it does not work without their hardware.
I have not had good luck with customer support from National Instruments.... I know they have a software that is Labview based.... has anyone used this software? It looks a bit intense based in the YouTube videos.
Is there any other software out there that works with this NI hardware? The software we use currently is not supported by the engineering firm that wrote it and it's plagued with bugs. It works well for Modal/ODS but is not really useful for data collection (which is also where the inherent flaws show up the most).
I did hear the other day that NI was bought by Emerson, so who knows what that will mean in the future.
Would appreciate any help you guys could offer!
Thanks so much!
