I would like to have a possibility to read data from Network Variables by using Windows 8 Metro applications running in Tablets and Windows phones. It would be very good, if I can implement the applications by using the next Measurement Studio release. Thanks in advance.
Plotting a big array of sample uses quite some time in the current version. I think this comes from Measurement Studio drawing a line explicitly between each two samples. However, in case of millions of samples, many of those lines will cover only one single pixel.
Instead of drawing all lines, it would be possible to sample the data at a rate where each sample matches just one pixel in the input axis. In order to not loose peaks, the sampling needs to do a min/max calculation and draw two lines for the minima and maxima. A shade could be used between the two curves. When zooming, the sampling needs to be repeated.
This feature would not only save much performance for big data (I think), it can also help to improve clarity of the graph, p.e. in case of noisy signals.
While it's great that Measurement Studio offers all capabilities for us to implement this functionality ourselves, such a feature could be of interest for many users.
Of course, this idea is not my intellectual property. It's a feature already implemented in other products.
I'd like to see some of the functionality contained in NI-VISA without having to install VISA on my system, but just set a reference to the library in my project. I'd just like to access devices/instrumentation through the serial port or usb without needing admin rights on every machine the runs the application.
Microsofts serial class has limited functionality. I like the reliability that comes with Visa.
I'd like to take advantage of Windows Presentation Foundation as the user interface for our data acquisition software. I'd like to see WPF graphs, switches, gauges, etc. with the ability to add the controls to XAML, databind, etc.
(Also wondering what happened to the beta version of Visual Studio 2012??)
I have been looking for an easy way to resample data with either Measurement Studio or LabWindows/CVI and came across the Rational Resample VI for LabVIEW users. It would be great to have this functionality in Measurement Studio.
At the very least it would be good to have an Upsample method to insert zeros into a waveform/signal. Then an FIR interpolation filter can be used on the upsampled signal to interpolate the signal.
Currently, it seems that the only versions of Measurement Studio are 32-bit. Since applications developed with 32-bit have certain limitations (particularly with memory usage), it would be great to be able to use NI analysis and filtering on larger files. Currently, this is a limitation that causes problems with processing some data files, and will only become a larger problem as the trend to store (and analyze) more and more information continues. Perhaps I'm missing something and there's already a 64 bit version somewhere, but I did contact support and they were unaware of anything.
It appears that the installer that Installer Builder produces does not check that the system has the required components. For example, my app uses .NET 4.6.1, but the app installed with no warning on a machine that had an earlier version of .NET and the app failed with mysterious errors that gave no indication that this was the issue. Microsoft's installers could check for prerequisites, and Installer Builder has to, too.
The MS grid control and all of the 3rd party vendors grid (WPF) controls data bind to an object that has a property for each column of data for example firstname, last name, age, phone number etc.
Well in Data acq say I had 250 channels I would need to create an object that has 250 properties on it. Doable I guess but what if the customer then decides to just show 200 channels I would need a different object for that.
I would want the Measurment Studio grid to be easy to add arrays of data (V, I, R etc). Then if the customer enables Power I could easily add a 4th column or if they stopped the acquisition have the option to append the new arrays of dat to the end of the existing data.
Show me a WPF grid that can do this with performace of course?
It would be great to incorporate the STM protocol into Measurement Studio, this would all an STM connection by just dropping the tool into Visual Studio, adding the IP and the Port, then collect data. The idea would be to incorporate Flattening and Unflattening of the data after connection to the STM server in the Labview Realtime. This can make everyones life much easier.
The IntensityGraph is a great control - but unfortunately its usefulness is hampered in the extreme due to performance issues. Basically the IntensityGraph.OnPaint() takes way too many CPU cycles. For a 500x150 intensity plot updating at ~10 Hz, this takes upwards of 30-40% of my PC's total CPU. Anything higher than that and my application becomes unusable due to latency problems. I really need to be able to show 2 or 3 times that much data.
Another user has separately reported an inability to display two 500x256 intensity graphs updating at 5 Hz.
We really need NI to address the severe performance limitations of this important control.
This may or may not be possible, but I'd like to be able to run my .NET program using real time. If this isn't something that NI can do because it involves hardware that isn't supplied or supported by NI, it would be nice to have some information on how it can be done. I recently saw some presentations by people that are able to use some real time kernel to get faster loop rates than I can get in Windows (9 Hz). This is the one major deficiency for Measurement Studio. LabVIEW supports FPGA and real time, and I can completely understand why FPGA may not be possible for .NET projects.
