Average on board the NI5922

Hello

Is it possible to sample 15 MECH. / s and calculate the average of the 15 samples on NI5922? That would be 1 MECH rusult. / s on average datapoints.

I use NIScope 3.8.1 and software LabView 10.0.1 (64-bit).

Thank you!

Tobi

If I remember correctly (and it has been a while), the 5922 has a 6-bit ADC and he gets the resolution by averaging.  So if you take a sampling frequency of 1 MHz, you should get the average time of the signal that you would get if you averaged 10 points taken at 10 MHz.  This is not true for other scanners high speed National Instruments (non-flex-resolution).

If you prefer to use an explicit sprawl, I rewrote your code and got an increase in speed of order of magnitude.  You can get more by turning off debugging in the properties of VI.  You can also upgrade priority Subvi, but don't do that if you can guarantee you will not be calling at the same time, or it will slow down you a lot.

Let us know if you have any other questions.

    It seems that your screen displays some graphical anomalies when you connect to your user name. I would use these troubleshooting steps in the following article on the resolution of screens:

    Restart your Mac in safe mode to reset the default display resolution.

    If booting safe mode doesn't resolve the problem, reset your Mac NVRAM and SMC to reset the video ports on your Mac to their default values.

    From: get help with graphics issues on external displays connected to your Mac.

  • calculation of the average value of the sorted data and polar route drawing

    Hello

    I did a VI that calculates the average value of the wind rotor/speed-ratio in the sections of 30 degrees (wind direction). He also called the polar plot of calculated data. Everything works, but I would like to make more detailed calculations and drawings, by increasing the resolution to 1 degree, or...

    Problem is VI, I did, is not easy on a large scale. At the moment, I have 12 parallel structures of switch-box to calculate the average value and build the array function to collect data calculated for Polar plot to draw the image in real time. I know it's probably the worst way to do it, but since I have done a few things with LV, it was the only way I managed to do what I wanted.

    Now, if I continue in same way to reach my goal, I have to create 360 Parallels switch-case structures... that are crazy.

    Something like the calculation of the average of the table or matrix (zero/empty values should not be calculated on average) inside the loop or similar way would probably be the best solution.

    So, polar plot drawing is not a problem, but creating a reasonalbe average metering system is. Any ideas?

    I would also like to rotare northward to the top (0 deg), and degrees of increase in a clockwise direction on polar ground dial plate (as on the compass).

    VI on the attachment. (simplified version of the complete system)

    I have signals:

    -Wind speed

    -wind direction

    -Rotor speed

    I want to:

    -calculate the average value of the speed of the wind / rotor - ratio in sections (5 degrees, 1 degree)

    -Draw a polar path of the wind rotor/speed-ratio of averages in propotion of wind direction

    I'm using LabView 2009

    Thank you very much.

  • VI data on average compared to the data from the Excel file on average .lvm

    I am trying to build a .VI to measure voltages on a channel of a transducer of pressure for a period of 3 minutes.  I would like the .VI to write all the samples of blood to a file .lvm with another .lvm file that comes from the average voltage over the period of 3 minutes.  I built a .VI making everything above so I think that... The problem I'm running into is when I opened the file .lvm of all samples of blood in MS Excel and take the average of them using the built-in Excel function (= AVERAGE(B23:B5022) for example) averaged and compare it to the .lvm file, which has just 3 minute average .VI voltage, they do not correspond to the top.

    This makes me wonder if I use VI with an average of function correctly or if maybe VI averages data different voltage than what is written in the .lvm file.

    Does anyone know why the two averages are different and how I can match.

    I have attached a picture of my functional schema with the file .VI for clarity.

    The Type of dynamic data of LabVIEW you use is a special data type that can take many forms.  It therefore requires the use "Of DDT" and "DDT" for the conbert to and from other data types.  These special conversion functions can be configured by double-clicking them and specifying the format you are converting from.  You can find the functions on the pallet handling Express-Signal.

    I've attached a screenshot of the modification of the code using the "DDT" and the average is very good.

    Please mark this as accepted such solution and/or give Kudos if it works for you.  We appreciate the sides for our answers.

  • How to get the average time of the day

    Hello

    Oracle 11g R2. Looking for a way to determine an average duration of the day. The data in the table are the following and are stored as VARCHAR2. These data represent the time of day a work finished and is stored each day in the table.

    (HH)

    00:21:45

    00:25:03

    00:23:09

    00:30:10

    Hello

    You want to use the AVG function, but that doesn't work on the number, it must convert the strings to numbers (for example, the NUMBER of days, 0-1), so get the average and then convert them to a string.

    SELECT TO_CHAR (TRUNC (SYSDATE) + AVG (TO_DATE (str, "HH24:MI:SS")

    -TRUNC (SYSDATE, 'MONTH')

    )

    , "HH24:MI:SS".

    ) AS avg_time

    FROM table_x;

    ATTENTION: the average of 23:50 to 00:50:00 will be 12:20, 00:20:00 not.  23:50 is 23 hours later at 00:50, not 1 hour earlier.

    Of course, you will get an error if even 1 of the strings is not valid.

  • Average throughput of the network to a virtual machine with PowerCLI

    I would get average network throughput for a virtual machine with PowerCLI including all e-cards, the virtual machine has for the last week (not including NFS or storage of traffic-related).

    How best should add this report:

    Get - vm myvm | Select name, numcpu

    Thank you!

    Try like this

    Get-VM | Select Name, @{N="Avg Network Throughput MBPs";E={    [math]::Round((Get-Stat -Entity $_ -Start (Get-Date).AddDays(-7) -Stat "net.throughput.usage.average" |    where {$_.Instance -eq ""} |    Measure-Object -Property Value -Average | Select -ExpandProperty Average)/1KB,2)}}
    

    The script takes the aggregate value for all NICs for (the one where the Instance is an empty string).

    Then we take the average and converts the Kbps, Mbps.

  • Average usage of the CPU with get-stat

    With get-stat, I can get average use of the processor in MHz using the metric usagemhz.

    However, by default the maximum and minimum values in MHz is not in data points from 2 months ago.  That's fine if I want to just average, but I also need average peak values.  The average maximum CPU usage is possible with powerCLI?

    The thing is that when you have found these averages and you do that a day or a week of a data value is not enough to really give you a true picture - you need 2 - 3 months.  Can Haw I achieve this with PowerCLI?

    1. you can easily adapt the cmdlet Get - VM to produce the result for 1 or a limited set of the virtual machine

    For example:

    Get-VM-name MyVM | Select...

    Returns the result for 1 computer virtual called MyVM

    If you do

    Get-VM-name my * | Select...

    It returns results for all virtual machines whose name begins with "My".

    2. that's because Select-Object generates a hash table, and by default PowerShell displays like that hash tables.

    To get only the value real exchange the last select like this

    ...

    } | Select AvgCPUMhz - ExpandProperty

    Is it possible to disable on board to intervene when the output line is used.

    Currently, if I plug in a cable to the socket of hadphone and choose alignment on the realtek Control Panel, sound is output line out as expected, but also through the internal speakers.

    Is it possible to stop this and don't have sound out through the output line?

    Thank you

    If you want to hear his helmet only you should choose option helmet.
    Disconnect the cable and reconnect it. When you see the small window on the screen where you can choose between the headphones and output line options choose headphones and you'll hear on external display only.

    In case you have disabled this pop-up dialog box you can activate it manually. Open the Realtek Manager connect the external device and when you see active point black on the right side make double click here and change the settings.

    RAM on most laptops is removable, as in desktop systems. There is a compartment memory inside of your laptop that you can open yourself, discovering the memory modules.

    You can test your existing RAM modules to find errors with MemTest (http://www.memtest86.com/). You just run the program, it copies itself on a floppy and with this diskette to start the tests.

    Your User Guide will be an article on how to install or replace a memory bar. Order number for a Toshiba memory of 128 MB RAM expansion is PAPA2062U. For more information about the Options for your laptop, you can visit this page: http://www.toshiba-europe.com/bv/computers/products/notebooks/satellite4090/index.shtm

    You can take a look at Kingston or Crucial to find the appropriate module for your laptop instead of buy a Toshiba that comes at a very heavy price because of the logo.

  • Cooling fan still works with an average speed on the Satellite A100-405

    Hello guys,.

    If anyone can give me a reason why my satellite cooling fan is always running at speed average. I shot all the "Toshiba Power Saver Properties" settings, to "Battery Optimized" condition and so I took the battery, and the pleasure of cooling is still running and operating at average speed. I'm in a place of model (18 Aºc) without any direct exposure to the Sun or heat.

    If you can help me about whether or not it is a normal condition. I think that it is not normal to have fun all the time for work. Runs normally for 2 minutes and stops during a similar period (used to be the case in other phones that I had in the past).

    Maybe, I need to set or check adjustments internally or in the Bios. I really don't know and I'm really worried about it.

    Thanks guys... Please respond.

    Laptop cooling depends on the use of laptops and the applications that run on the laptop.
    Strong performance of the software is running on the laptop each part as CPU and GPU produce a lot of heat.
    Have you tried to use a material like Speedfan monitoring tool.
    SpeedFan is a freeware program that monitors voltages, fan speeds and temperatures in computers with hardware monitor chips

    But back to the energy saver. In the eve of power configuration, you should try to the CPU for auto control method and try to change the processor, the speed of processing and cooling method.

    Don't forget that there is enough free space around the laptop. It is important for the circulation of fresh air.

    • Use WaveformPlot.MapDataPoint (...) to convert x and y values of the Point data (i.e. pixel)
    • Use WaveformPlot.InverseMapDataPoint (...) to Point to the x and y values of data.
    • Use the WaveformPlot.GetYData () to get the data that you traced.
    • Use the WaveformPlot.GetXData () to get the coordinates of each point you data plotted on the graph. By default the value in the table XData [If you used the method of foot (s)] are essentially calculated from the WaveformPlot.DefaultIncrement and WaveformPlot.DefaultStart. So using these you can calculate the double [] index.

    Use above methods to do all the stuff you want.

    For example, to get x and are given where the mouse click, you just use the WaveformPlot.InverseMapDataPoint () to the location of the mouse click.
