Time between CH1 and CH2's waveforms

Hi Everyone,
As per attached picture, I need to measure the time between the STARTING time of CH1 (rising) and END of CH2 waveform (rising).  Could anyone provide some sugestions as to how to accomplish this?  Thanks very much,
Frank

Dennis,
As I mentioned before it looks like there is a problem or bug with the Basic_Level_Trigger_Detect function.  Everytime that I open this vi it appears as a "clone" copy and I can not change any of the invisible controls.
After I replaced these vis with new vi's from the palette, I can change this control from invisible to visible.  Then after running my program the Basic_Level_Trigger_Detect function will revert back to "clone" again.  I changed the number of trigger setting to 10 and also reverted back to 1, even though a new copy from the palette will have 10 times on this setting.  Please see attached code for more info.  The text file contains the failure data.  Again it seems that the Basic_Level_Trigger_Detect function is not very dependable or releable.  Thanks,
Frank

  • "logon time" between USR41 and security audit log

    Dear colleagues,
    I got a following question from customer for security audit reason.
    > 'Logon date' and 'Logon time' values stored in table  USR41 are exactly same as
    > logon history of Security Audit Log(Tr-cd:SM20)?
    Table:USR41 saves 'logon date' and 'logon time' when user logs on to SAP System from SAP GUI.
    And the Security Audit Log(Tr-cd:SM20) can save user's logon history;
    at the time when user logged on, the security audit log is recorded .
    I tried to check SAP GUI logon program:SAPMSYST several ways, however,
    I could not check it because the program is protected even for read access.
    I want to know about specification of "logon time" between USR41 and security audit log,
    or about how to look into the program:SAPMSYST and debug it.
    Thank you.
    Best Regards.

    Hi,
    If you configure Security Audit you can achieve your goals...
    1-Audit the employees how access the screens, tables, data...etc
    Answer : Option 1 & 3
    2-Audit all changes by all users to the data
    Answer : Option 1 & 3
    3-Keep the data up to one month
    Answer: No such settings, but you can define maximum log size.
    4-Log retention period can be defined.
    Answer: No !.. but you can define maximum log size.
    SM19/SM20 Options:
    1-Dialog logon
    You can check how many users logged in and at what time
    2-RFC login/call
    Same as above you can check RFC logins
    3-Transaction/report start
    You can see which report or transaction are executed and at what time
    (It will help you to analyise unauthorized data change. Transactions/report can give you an idea, what data has been changed. So you can see who changed the data)
    4-User master change
    (You can see user master changes log with this option)
    5-System/Other events
    (System error can be logged using this option)
    Hope, it clear the things...
    Regards.

  • Best way to capture data every 5 ms (milli-seconds) in the .vi diagram when using "Time between Points, and Small Loop Delay tools" ?

    - Using LabView version 6.1, is there anyway to change the "Time Between Points" indicator of (HH.MM.SS) to only (mm.ss), or to perhaps only (.ss) ?
    - Need to set the data sampling rate to capture every 5 milliseconds, but the defaults is always to 20 or greater; even when the "Small Loop Delay" variable is adjusted down. 
    Thank you in advance.

    I have no idea what "Time between Points, and Small Loop Delay tools" is. If this is some code you downloaded, you should provide a linke to it. And, if you want to acquire analog data every 5 milliseconds from a DAQ board, that is possible with just about every DAQ board and is not related to the version of LabVIEW. You simply have to set the sample rate of the DAQ board to 200 samples/sec. If it's digital data, then there will be a problem getting consistent 5 msec data.

  • Switch between log and linear in waveform graph

    I have a waveform graph that plots linearly. however it creates an error when plotting a logarithmic line. Is there anyway to create a switch that allows me to change the plot between log and linear without creating extra graph?
    Thanks
    Chris
    Solved!
    Go to Solution.

    Use a property node: Y Scale.Mapping Mode.  Writing 1 to the node switches to logrithmic mode and 0 is for linear.

  • Wait time between DTP and InfpoPackage

    Dear All,
    Is it possible to set a constant / dynamic delay / wait time between a DTP and infopackage. I've following scenario in my PC:
    DSO --> DTP --> Open Hub Destination (AppServer-Folder) --> InfoPackage --> Flat File DS
    Regards,
    Ender

    Hi Ender,
    There is a easy way to do this .
    Go to PC ->edit mode ->right click on process ->Debug loop ->it will ask for waiting time in seconds  .
    For some of the processes it shows option wait in place of debug loop.both are same .
    Hope this will be helpful .

  • Lived in germany for 1 year and changed dvd player setting 6 times between 1 and 2

    Hi i lived in germany for one year and had american dvds with me and chnaged between german and english more than 6 times now i am in america and only can watch german videos.
    Does somebody now how to change a 7th time?

    Wikipedia has some more information in this article, DVD region code:
    In most computer drives, users are allowed to change the region code up to five times.[10] If the number of allowances reaches zero, the region last used will be permanent even if the drive is transferred to another computer. This limit is built into the drive's controller software, called firmware. Resetting the firmware count can be done with first- or third-party software tools, or by reflashing (see above) to RPC-1 firmware.

  • Outlook - Difference time between inbox and sent

    we used Outlook 2010, and our e-mail server is hosted outside the company. Nowadays, in some computers, there is a difference between time in inbox and time in sent . for example, we sent e-mail at 10:40, the delivery report shows 10:40 but it
    bearing in sent at 11:40. on the other hand, when we open mailbox from internet explorer through OWA, the inbox and sent time are correct which is 10:40. We release Microsoft fix it 51015 but still no change happened. could you please help us. we used Windows
    7or xp

    Hi,
    According to my knowledge, the issue may be cause by the incorrect time or time zone settings on one of the computers. To confirm it, we can firstly verify all computers involved are set to the correct time, time zone and daylight savings time settings in
    Windows Control Panel’s Date and Time applet.
    If you have any question, please feel free to let me know.

  • What's the best way to sync the time between FP and host?

    I have tried with Set Date and Time (Client).VI and Write Time to FP RT Module (Server).VI in order to synchronize the time, but I have got different behaviours running this VIs. Is there any recommended way to do it?

    The easiest way would be set the host to be the time server of the FP module. The host would have to be a static IP address and running the Logos Time Server. Otherwise if you have LabVIEW RT 7.0 there is a VI in the RT>>Utilities palette which allows you to programmatically set the time of the FP module.

  • My iPhone would just randomly give me a blue screen and then restart--did that a bunch of times between Tuesday and last night. As of last night, it WILL NOT come back on. iTunes says it's in recovery mode....what does all of this mean???

    Tuesday night I was texting a friend and when I went to open her message, my screen went blue and restarted. I just wrote it off as weird and went on about my business. Later that night, I tried to turn on my phone and it would not turn on. I plugged it up, held down the power button, and pressed the home button all numerous times. I looked online and it said to do a "hard reset" by holding down the power and home button at the same time--my phone then came on. Throughout Wednesday, it would give me a blue screen and restart--nothing major just really annoying. I took it to the local Verizon store where I bought the phone from and he said that it was some type of hardware defect and I was still under my year warranty so I could get a new one for free--the free phone won't be here until tomorrow, Saturday. I took it home and it didn't give me any trouble for a couple of hours. The next day it was cooperating and then I left town for a little while and it acted up (blue screen and then restarting) a few times. When I got home, it acted up again and so I restarted the phone and it was working fine. A few minutes later, I tried to check my messages and the phone was off again. No matter what I do, my phone will not come back to life. It had at least 45% battery last time I looked at it. I decided to plug the phone up to my computer and see what it did--my computer recognizes that there is a phone hooked to it and it says that it's in "recovery mode". It also said that if I'm having issues with my phone, that I need to reset the phone via iTunes. I guess the questions that arise are
    1. Why is my phone doing this?
    2. If I reset my phone, will it go back to working again? I ask that because I don't want Verizon to charge me $300 when they send me the replacement phone and I won't need it (assuming that the phone decides to work once it's been reset).
    3. What type of hardware defect is this that is causing this issue, not only with my iPhone 5S but others as well?
    4. Shouldn't people be notifying Apple and letting them know that they need to fix this issue?
    5. Should I report this issue to Apple even though I didn't buy the phone directly from them, but through Verizon?
    Any help that anyone could give me would be greatly appreciated! This whole situation has me stressed out and seriously confused.

  • Lag time between Client and WebDAV Update

    If I check out a file, make modifications, and then check it back in - it is immediately visible to everybody who connects to server via VC Client software (ie, Bridge or Adobe Dialog.)
    However, it takes several minutes (up to ten) for the same change to be visible to people who are connected to the server via WebDAV.
    A ) Is this related to Version Cue not pushing the correct data (the "stat" on the file give the correct date. The file will say it was modified at the write time, but opening the file gives the wrong data.)
    B ) Or is it a Mac system thing, where it is caching the WebDAV data?
    Thanks,
    Stephen

  • Lag time between instrument and GB

    I'm trying to lay down some bass lines. I'm running a Line 6 PODxt Live via USB into a Mac Mini which is a G4 1.25GHz with 512 of RAM. There seems to be about a half-second delay between what I'm playing and what actually gets recorded. Is there a way to stop this?

    This is called "Latency" and is a product of the processing a computer does before it plays the sound (i.e. the sound goes through an A/D converter, into the computer, it's written to hard drive, perhaps processed with some digital effects, etc)
    The first thing you can try is setting GB's preferences for "Less Delay". Also, if you're using any effects (Like one of the bass Amp Sims, I'd try skipping that during the recording)
    Hmmm, and thinking a little further, I don't know anything about that interface, I'm assuming it doesn't offer a Zero Latency Monitor, but if it does, monitoring directly from the interface can eliminate latency.

  • Render time between fcp and motion

    I make my own project in motion 3, this project is something like a slideshow but I used a new camera, a light, and the images (png files) in a 3d way. the number of media in the scene is always low, one ore two without filters too. Anyway, when I export the animation directly from motion to a .mov file I obtain a render time very quick, but if I import my motion project in fcp I can't work with this; just the visualization time is prohibitive! than when I export through compressor or directly from fcp tha application crash!
    so my question is what elements fcp doesn't like? light? camera? 3d elements?
    this time I solved the problem exporting my clip from motion like file.mov but I only move the problem... I cant't archive my project, it's to big!
    thank you

    In my experience, these problems are more likely to crop up when using oversized images. Especially those greater than 2k or 4k (depending on your card). Motion gets a larger "workspace" on its own than when invoked to render from within FCP or Compressor...

  • Great difference in export time between single and multipass modes. Why?

    Hello.
    QuickTime 7.6 Pro, MacBook MB402 (Intel Core 2 Duo 2.2 GHz, 2 GB RAM...). The source movie in mov format should be converted into mp4 H.264 using QuickTime Pro export functionality.
    Choosing some settings and singlepass mode gives us the result in adequate period of time (not so fast, but curtain). The same settings but with multipass mode hands the encoding process on uncertain amount of time.
    In case of multipass encoding small window with progressbar appers, then progressbar quickly grows to approximately 10-15% and stops. After 40 minuts of encoding of 20 minutes long movie progressbar hasn't changed from initial 10-15% position. It seems to me the encoding procedure just hangs, because it's impossible to encode 20 minutes of video such amount of time.
    The question is how to resolve the problem with QuickTime (not to choose anothe encoding software)? Does anybody meet the same problem? Is there any solution?

    Multipass will always take longer than single-pass, since it will go over the encoding several times to ensure optimal quality and compression in the final file. For me, an hour-long video will take ~6 hours to encode using Multipass.
    This is a bit longer than it took in previous versions of QuickTime though.
