Time of exposure with MC1362 externally triggered and PCIe-1433

Hello

I'm capturing images with the help of a Microtron EoSens CL MC1362 camera and NI PCIe-1433 acquisition card. I have a question about exposure times - I don't know if it is related to the acquisition, the camera or the combination card, but I hope someone here can help you.

I'm running an external signal to the SMB connector on the card acquisition and the camera set to run in "Mode Pulse width", that allows to the capture card to take control.

My question is:

How can I determine the exposure time in the settings of the external signal? It is a square wave, and the cycle seems to control the exposure time.

I guess the exposure time, E = (D/f), where f is the frequency of the signal and D is the duty cycle? for example, for f = 1 kHz, and D = 80%, exposure would be E = 0.8ms. Is this correct?

The manual of the device can be found here:

http://G4.com.tw/Web/file/product/UserManual/995-EoSens%203CL-MC1361-manual.PDF

and I've included a screenshot of the revelant portions that seem to describe how the pulse width. In particular, he said "exposure time is defined by the width of the external signal. Which is equivalent to my idea of E = D/f?

Thanks in advance for any help.

This looks good to me.  The exhibition remains on while the pulse is high.  When you calculate E, you're just calculating the duration of the pulse is on.

  • Problems with the Ethernet controller and PCI Satellite L30-10 X device driver

    HelloW!

    Sorry for my bad English, I'm from the Russia.
    A few days ago, I bought Satellite L30 - 10 X with W Vista on board. In my opinion, that this OS does ' t very good on this computer, so I install W XP.

    I have some problems with drivers. At first, I don't know which model I have: PSL30 or PSL33? I have download all the drivers for the two models. But after installation, computer doen't find the drivers for the Ethernet controller and PCI device...

    Hello

    Satellite L30-10 X belongs to the series of PSL33E. This number located on the label on the bottom of the device!

    You must choose this number in the form of driver download for XP compatible drivers.
    I put t know why you are not able to install the LAN driver. I have the same laptop with Vista and I've install the XP and all the drivers will work perfectly.

    I assume that you have installed the drivers in the wrong order. Please take look in the Toshiba installation instructions txt file. In this order, install the driver! This is important.

    I think that you should install XP again to ensure that the registry clean, then download and install the XP drivers compatible as mentioned in the installation instructions file.

    Good luck

  • RelativeInitialX is valid for the externally triggered measures? NEITHER SMU 5122 64 MB per channel

    For example when you use the following commands

    niScope_ConfigureDigitial (with a positive delay)

    NiScope_SetAttributeViInt32 (NISCOPE_ATTR_FETCH_RELATIVE_TO to NISCOPE_VAL_READ_POINTER)

    followed by

    niScope_FetchBinary16 (loop to retrieve the data most wfmInfo)

    What will be the value of the wfmInfo.relativeInitialX before the external trigger?  It matches?  It is set to a number to indicate the outbreak did not appear until the trigger has been received and it then becomes accurate after receiving the trigger?

    I would use it to make a set FecthForever to date, but synchronized to an external trigger waveforms up to about a minute.

    It seems that the delay of release for the 5122 should be able to hande a minimum delay time of about 170 seconds (at the max rate of sampling more at lower rates), so the data I would need could all be borrowed buffers read-ahead externally triggered and properly after off-delay measurement.

    Thanks in advance for any advice.

    Greg

    In the case that you are extracting data from before trigger (extraction of data before a relaxation was produced., relativeInitialX will have the same value as absoluteInitialX.)

    Kind regards

  • I use Envy 17 with a job posting and I need to be able to turn it on even if the lid is closed? Thnx

    Hey! Regarding my HP Envy 17 1085 eo. I use my Envy 17 with an external display, and I have to be able to turn on my pc, while the cover is closed (clamshell). It is possible while the pc is in "standby", while activating the mouse keyboard og - but Windows break mode standby after a certain time, leaving me frustrated as I then need to open the lid of my desire and press the button 'walk', to use the Windows. Is it possible somehow? Thank you very much!

    Hey dhalb_,

    Have you ever watched the Power Options window (start > type 'power' > click Power Options) where you can change when the computer sleeps (left)? As long as you stop the computer periodically (2 - 3 times a week, if you use it every day) it would be nice to never go in "standby mode" while it is plugged.

    For a while, I used a laptop as a desktop replacement with an external monitor and ran into the same frustration as yourself. I shut down my computer after each use if so I came up with a scheme where I could leave the screen all half open, just enough to be able to press the power button.

    If you prefer to go in standby mode, you can go to the advanced power settings (Power Options > change Plan settings next to the selected power management > change advanced power settings), extend your sleep and set "Hibernate after" connected to never by typing 'Never' in the field minutes. Click on apply and OK.

    I should mention that it does not extend the life of your computer to run constantly. Hard drive failure and the motherboard issues sees much more often on machines that are constantly running. Computers bogged down and run slowly when the memory is full. Memory erase them and will reset when the computer is turned off. Here's a link explaining more on the accumulation of memory and aging of the material.

    I hope these suggestions help. Please let me know if you have any questions.

  • External mouse and keyboard do not function correctly on the Satellite Pro C650

    I have problem with my external mouse and an external keyboard. All started about 3 weeks ago. They freeze, jump or a stop, the most annoying is the mouse, I need to plug it back usually. This will work well about 1-5 minutes and once again. Touch Pad works well.

  • Synchronization of analog and digital output with the external sample clock

    Hello

    First of all sorry for my English, I will try to explain what I want to do.

    I want my PCIe-6321 to send two custom signals (modification sawtooths) on a mirror controller. I would also like to generate output with my card at the beginning of each tooth of saw. Everything must be synchronized with an external k-clock signal of 100 kHz. The idea is that whenever the PCI receives a trigger to external clock, it sends two analog output voltages and when he received 1024 clock ticks it will also send a pic of triggering TTL. What I do is first prepare the map and after that in a loop sending and modifing the output values of the two signals and at the same time send a digital signal Boolean in each arch, so when's done it 1024 iterations of the loop I send an event to the digital port. Attached you can see.

    The problem is that I don't know how to synchronize both. Can I use the sample clock just to the analog output? I can use sample for the two outputs clock, or do I need to use the output of the meter? If don't know how to use it here.

    If I do nothing else bad/wrong, I would be grateful for feedback.

    Thanks in advance,
    Pablo

    I don't know how but I find the solution. I'm generating more than a positive value (as I was triggered maybe very fast the oscilloscope has been absent there). If I put the sample clock of digital output to use the sampling/ao/Dev1 clock that it doesn't, but if I put to use the same source as the OD (terminal where my external clock is connected), but the trigger to start the DO to be Dev1/ao/StartTrigger this works. I don't really know why, but it does.

    Thank you for your patience and your help. I put here the final code.

  • Several laptops, external wireless and Time Machine

    I have three MacBooks, I want to connect it to Time Machine, but getting three external wired systems is not going to work. In my family, no one sits in a single place that would connect to a device.

    I've been watching based cloud like Backblaze subscription services, but a subscription for three machines is more expensive, then buy an external wireless that we can share. (Plus, I like and want, the time Machine interface, and Backblaze doesn't only.)

    He who stands by me and was recommended by a friend is 'My cloud.' Western Digital

    However, I'm trying to find out if I have three machines use a single external for three different instances of Time Machine. My first thought was that I could divide a disk into three partitions of 1 to 3 TB, but I called their customer service and they said that partitioning would not work. However, I can create three separate 'folders' that work with the separate MacBook. I didn't think it was possible. When I used TM in the past, and I use it connected to a G5 tower, he formatted the drive especially for the backup. And I have not found any instructions on the use of sections of a player.

    Before that I have to spend money, I wanted to make sure that it is possible to what they describe.

    You can bind Time Machine in specific folders on an external?

    If someone has a different suggestion, which would be also welcome.

    Thank you.

    You can bind Time Machine in specific folders on an external?

    Yes. I save 2 computers in a time Capsule that is not partitioned.

    Apple officially supports the time Capsules for network backups. If you look in the section updated the Apple store, you can get one for a reduced price with the same warranty as a new one. After trying a few other brands for the backup of network backups, I went to all the time Capsules and in my experience, they work.

  • Error ' ' system timer was triggered "and hibernation / sleep problem.

    Original title: Hibernation and sleep problem?

    I bought a new laptop of Toshiba C55 series probably a little a month ago and for a while, it was fine, I had no problem. I had some mistakes with what is called a bad pool header, I've not experienced this once again. My main problem is with the sleep and hibernation. I went and disabled any parameter that would be extended automatically to my computer after a short period of time. It is set at only hibernate after like five hours, I'm never away from him that long. I don't want it to hibernate unless I put it specifically put into hibernation. I heard talking about hibernation is hard on your computer. I am usually only away from him for a couple of hours, so it's easier to have it in sleep so I can come back and get the right to return to work or what I was doing. I put it in mode 'sleep' whenever I need to go away for a few hours, for some time, I had no problem, he would go to the mode standby and stay there until I woke it. My problem is that most of the time when I put it in fashion watches, it goes to the hibernate after only a few minutes. WHY would he do that? And how can I stop it? There are times that I put him to sleep and he done as it should. Most of the time, but it goes to the hibernate after a few minutes. I don't want to make this period. Is there a setting I'm missing, I have conflicting settings on something? What is a small problem with Windows 8, or with my computer itself? The last thing I want to do is to restore it to factory settings and lost all the things that I have saved and have to reinstall my programs again.

    There is also something else showing in my event viewer I've ever seen before. That means when he says "system timer was triggered." And can someone tell me what means the bad pool header error and how to fix it?

    I found a solution, I noticed when I Hibernate the computer at night to go to bed is when it remains not in mode 'sleep'. I stopped it in hibernation at all now and it says in the mode "sleep" very well.

  • Hi, I put all my files raw on an external drive and add directories to lr. Is this way of working with slower rawfiles?

    I know that, of course, that's a (usb2.0) connection slower than my c drive which is ssd, but what happens when I in develop mode? is the file copied into memory or lr works with the external drive permanently? I only have a small ssd disk so I can't have y rawfiles on my c drive: () I got the idea of having a working directory on drive c, but is it really necessary? -What is much slower to work from my external hard drive?

    As long as the catalogue LR, file Previews and the camera Raw Cache not located on your C: drive faster shouldn't you see a loss of performance module develop. The library module, you can build Standard previews when importing and updating when editing images. After modifying a group of images in the develop module, select all the and go to the menu library > previews > Build Standard - Sized Previews. If you need to return to a group of images to 1:1, select them and choose Build previews of 1:1. Keep in mind that the library module should be used to review and rating of groups of images because it uses the already rendered previews. The develop module makes the images in real time. What is significantly slower. Following these procedures of workflow you shouldn't have performance problems with the images on an external drive.

    By default, Time Machine will exclude your second drive unless you have included it. Did you?
