How can I reduce channel time reconfiguration between AI acquisitions? thanks

Hi everyone,
I need to acquire 40 sin signals (2000 kHz) at a sampling rate of 250kS/s per channel using a 6225 daq card with its AIs. In order to reach this sample rate I have to acquire all of the samples of the first channel (something like 2000 samples), then the same thing with channel 2,... up to channel 40.  My problem is that I am loosing a lot of time (roughly 170 ms) each time I move up one channel because Labview reconfigures the channels.
When I move up one channel to acquire the 2000 samples the only parameter that changes is the channel that's all.
I have tried a few things with the assistant DAQ and Daqmx examples but without any success. 
Is there a way to reduce this paramating time between 2 acquisitions ...?
Any help would be great.

Hi Denis and LV,
Thanks for answering.
My purpose is to capture the 40 signals and get the RMS value of each of the channels (using one of the RMS.vis). 
I had already tried capturing the 40 channels at once (infact I only tried capturing one channel at 6.250 Ks/s) but the RMS value isn't correct enough (the value isn't stable). I have attached my VI and saved 10 of the RMS values in the array to show you.
Thanks,
User

  • How can I put a time delay between specific events in a while loop?

    How can I put a time delay between specific events within the same while loop? I'm already using the "wait" command to control the overall loop iteration speed. But I want to time the individual events as well.

    Hi Jesse,
    You can use a flat sequence. In each box you can put your individual events and attached wait.
    Don't forget to reduce your total loop time of the time you added in the individual sequences.

  • How can I reduce the time between songs to zero for seemless mixing

    Hi, Ive only just got my 5th generation Ipod and was wondering if its possible to reduce the time gap between songs to zero. I.E a lot of Cd's and albums I have are mixed so it doesnt seem there is a pause between each song but when I put the cd's onto my ipod there is still a pause.
    For example I have a 2 many djs album which is heavily mixed with a new song every 30 seconds so it is a bit of a nuisance if there is a pause every 30 seconds.

    Your question gets asked on a daily basis, and has been answered many times. If you search for 'gapless playback' you'll see how just how many people inquire about this.
    In short... the iPod does not support gapless playback.
    If you want to eliminate the gaps, one workaround is to join the individual tracks together, and play them as one single track. You can do this by reimporting the CD into iTunes using the 'Join CD Tracks' feature.
    See Step 3 in this article:
    http://docs.info.apple.com/article.html?artnum=93079
    If you'd like to send feedback to Apple to ask that they include gapless playback as a feature in future revisions of the iPod firmware, you can do so on this feedback page.

  • How can I measure the time difference between spikes (interspik​e intervals)

    I have used NI USB-6008 (DAQ) to sample a continous signal, after sampling I compared the amplitude of the resulted signal with a value. If the amplitude is greater than a specific value (threshold) then it can pass. Now I want to measure the time difference between the resulted samples. The samples look like spikes. (May be if I trigger a timer, then I can measuer the time difference, but I have not seen such a timer). 
    Thanks in advance,
    Saraydin

    Oops just occured to me that you are using a 6009 which is not very fast, 48ks/sec, this will not get you very much time resolution and you could have issues seeing much of a 50 us sample.  Another approach is to use the counter but you would have to preprocess the spikes to generate a trigger for the counter.

  • How can I reduce the time it takes to save and close my TIF files?

    It takes me six clicks to save my manipulated files to tif and close them.  Isn't there a way of setting the tif settings so that it doesn't prompt you for them each time?

    OK, let me back up a bit and make sure I'm thinking correctly about what I've done. I'll answer Shane's questions here, too.
    The video clips were shot on a Panasonic PV-GS500. They are DV Movies - DV/DVCPRO - NTSC. I brought them into iMovie, then I stored them on my desktop and transferred one of them into my FCP project, which is on the external drive I mentioned above. The wav file from the H4n is also stored on my desktop, though I imported it into the project.
    Is my project still referencing the original video and audio clips from my desktop? I can see how that would slow things down.

  • How can I reduce total time after deleting a transition

    Hello there !
    I recently made a quite long 1:51 minute animation with rather complex timeline.
    Now, It happened that I want to delete some middle animations (at 0:18 or something)  and reduce the overall video time. I am finding myself at totally loss when readjusting each transition.
    When I delete the middle transition and try to pull back other transition, I can't since there are already so many of them and they wont move when they collide with each other.

    Itunes remembers what u have downloaded (free and paid apps) so if u have to 'authorize' the computer again as a new computer, (u r allowed 5) itunes will just reinstall apps and app info eg saved games scores etc will be still there after restore or update.

  • How can I reduce my time required for rendering?

    Hello,
    I guess I'm used to an editing environment where I never had to really render in order to review my most recent edit. I do miss that.
    Right now it seems that even for the most minor of insert edits and the like I am asked to render my media in order to view the sequence in video, as opposed to just still frames.
    Am I missing something here?
    What settings can I change?
    I don't need high rez playback just some way to avoid having such a very high percentage of my time in the edit process spent rendering.
    Thanks,
    matt

    Thank you. I was forced to change platforms, to FCP at the very last minute. I appreciate your help.
    I wish this forum had the capability for screen shots. That is so much more efficient.
    These clips were created by my color grader yesterday, apparently in QuickTime, and the compressor is listed as H.264. The rate is listed at 5.5 megs/second, 1920 x 1080 aspect ratio, shot in 24p.
    My sequence setting is at 1920 x 1080, but is set at HDTV 1080i.
    I wonder if the interlaced/progressive difference between the two is important.
    Thanks for your help.

  • How can I reduce the time it takes to render my clips?

    I'm working on a MacBook Pro, 2.4 GHz Intel Core 2Duo machinewith 4 GB 667 MHz DDR2 SDRAM, usinf Final Cut Pro 6. In my current project I have one clip that's about 40 minutes long. I recorded separate audio on a Zoom H4n and the audio clip is even longer. I am going to try to sync up certain sections of these clips and replace the audio from the camera. But right now, my computer seems to be choking on these files. I know there is a way to edit at less-than-full resolution, and then output later at full resolution, but I don't remember how to do this. Any suggestions?
    What I really want to do is ask the boss for a more powerful computer, but, budgets being what they are, I need to make sure I've tried every trick in the book first to get the most out of my current setup!
    Thanks!

  • How can i compute the time elapsed between two pulses or the period of an encoder signal if I dont have a constant rpm?

    I need to compute the rpm of an engine using information from an optical encoder attached to it. the engine is running in transient mode so the encoder pulse doesnt have a constant frequency. I need to get the period betwwen two rising or falling edges using DAQmx.
    Any ideas?

    Using an M Series or TIO device you can measure the period between two edges (on two different signals) using the two edge separation measurement.  I'm assuming that you don't want to use position measurement because the frequency is varying so much?  If not, you may be able to set the sample clock period short enough that you get a decent average RPM measurement.

  • How can i reduce applet loading time?

    I have recently begun converting a gui application to an applet. The problem i have is the loading time of the applet which can be several minutes.
    The gui has a progress bar which tracks the loading of the classes, images and sounds etc, once this is up and running the loading time is fairly short, however it takes forever for the gui to actually begin to display.
    The code for the classes is only about 150K altogether, there seems to a period of long modem inactivity once the applet is initialized before the gui is displayed.
    How can i reduce the time it takes for the applet to initialize before the gui is displayed, otherwise users will thing nothing is happening and not bother loading it.
    the applet is currently at http://www.winnieinternet.com/games/startrade2095/applet/startrade2095.htm
    if you need a demo of the problem, although the applet is still work in progress.
    Many thanks in advance for any help

    Some suggestions could be:
    1. Bundle all classes and resource files in a jar file.
    2. Try to preload the heavier files (e.g. sound files) in a background thread, instead of init() method. See an example for this in Sun's Java tutorial, under the trail 'Sound'.

  • How can I reduce the size of the jvm?

    I would like to decrease the size of a jvm; I've found a program that makes it, but you don't know how does it works (and you have to pay for it), I'm talking about VM Optimizer 2.0, from Invirtus.
    Can anyone tell me how can I reduce the size of the jvm?
    Thanks a lot.

    I assume you mean the size of a JVM instance in memory and not the size of the JRE which is on the disk.
    I don't believe that there is any way at present for your Java code to change the amount of memory available to the JVM. This shouldn't matter too much, though. Firstly, you can control the size of the JVM from the command prompt with the -Xms and -Xmx options. Secondly, any remotely reasonable operating system is going to wait until the JVM has requested memory before allocating all of it. If you start a JVM with a 2Gb heap, it does not occupy 2Gb of physical memory straight away.
    Finally, I did a Google on InVirtus VM Optimizer and must request some information. What does that software have to do with Java? It's designed to reduce the size of a virtual computer as created by a prorgam such as VMWare. It has nothing to do with the Java virtual machine.

    Keep in mind that Logic also has a limit of 8550 quarter notes. So changing the time signature to 4/8 can get longer recording times. So make sure you change this setting along with the song end. See page 93 in the reference manual.

  • How can we reduce Row Chaining?

    In a 10gR2 db, how can i reduce row chaining in tables?

    Hi,
    First, the prevention techniques for chained rows vs. migrated rows is a bit different. Note that both chained rows and migrated (relocated) rows manifest as "table fetch continued row" in v$sysstat and stats$sysstat for STATSPACK and dba_hist_sysstat for AWR.
    Preventing chained rows - Chained rows can occur when a row is to large for a data block. In these cases, moving large objects into a tablespace with a larger blocksize can often relieve chained rows.
    Preventing migrated rows - Migrated rows occur when a row expands (usually w2ith a varchar2 data type), and there is not enough reserve defined by PCTFREE for the row to expand. In this case, you adjust the PCTFREE to ensure that future rows will have room to expand and reorganize the table to remove the fragments.
    On some tables which are stored tiny and grow huge, you may need to set PCTFREE to a "large" value, so that only one row is stored per block. For example, if I have a row with a varchar2 that is stored at 2k and grows to 30k, I would need to use a 32k blocksize and set PCTFREE=95 so that only one rows is stored on each data block. That way, at update time, there will be room for the row to expand without fragmenting.
    Operationally, Oracle consultant Steve Adams offers this tip for finding the difference between chained and migrated rows:
    http://www.freelists.org/archives/oracle-l/10-2008/msg00750.html
    +"You can tell the difference between row migration and chaining by listing the chained rows with ANALYZE table LIST CHAINED ROWS and then fetching the first column from each "chained row" in a single query.+
    +The count of continued row fetches will be incremented for every migrated row, but not for most chained rows (unless the first cut point happens to fall with the first column, which should be rare)."+
    Hope this helps . . .

  • How can I reduce the bit rate of songs in my Music Library to enable me to

    At the moment i can only fit about 1300 songs on my iphone and also have used up half the space on my 120gb Classic with 7000 songs which is a lot less than what i was told would fit on. so............
    How can I reduce the bit rate of songs in my Music Library to enable me to fit more songs onto my iPhone or iPod Classic.. and what is the minimum rate that i should stick to in order to retain good sound quality.

    For existing tracks, see:
    http://support.apple.com/kb/HT1550
    For CDs you import in the future, change the Import settings in the iTunes -> General preferences.
    As to what will be a good bit rate, that's going to be up to you and what quality you find acceptable, but many people find that 128 kbps AAC is the optimum balance between small file size and quality.
