SR400 Triggered Gate

Hello

I used a LabView program to collect data from SR400 via GPIB.

Now basically what I need is that we send the signal TTL SR400 and leave only the signals of photons in the synchronization time we want to get through.

That is why we want to use high (low) pressure to open the door and use the low tension to close, which means that we use the external signal to control the width of the door.

However, the width of the door is determined internally.

Could you please tell me how can I leave the signals of photons in the duration of synchronization we want to pass through?

Thank you!

Hi PbZhang,

It seems that the SR400 has a minimum of 5 ns door width and a maximum of 1s so door width as long as your desired door width is within this range, you should be fine.

The forum post below contains an example that VI attached which is a good start. I recommend to use it as a model

  • simulateneous of analog and digital triggering

    Hello

    I have an experience that is very similar to this announcement:

    http://forums.NI.com/T5/LabVIEW/how-do-I-reset-the-arm-trigger-with-DAQmx/m-p/2006639/highlight/FALs...

    As in the display, I need trigger out of logic AND low frequency (3 Hz) and a signal of high frequency (100 Hz).  However, my experience is different because my low-frequency signal is an analog of entry (AI0) and I need experience to trigger off each edge of the signal change high frequency, while the analog input is high.  To do this, I created a trigger to HAVE that starts a counter whose state high and low are similar to that of my analog input signal.  I then export the output event from the meter to a port (PFI8) and pass this signal and the other signal high frequency through a door AND as in the posting linked above.

    So far, everything works.  I've included a VI that is just this part.

    However, I then connect the output of this gate AND a PFI0 port and use it as a digital triggering to read an AI0, 1 channel.  When I perform this final step, my whole system stops working, but gives no error.  To troubleshoot, I measured the output of the meter to the port of PFI8 has stopped working and the port of PFI8 remains in the low state.  For some reason any when I add the channel HAVE additional (AI0 or AI1, whatever) with digital trigger (PFI0), everything grinds to stop.  I have also included the VI for this case.

    Any ideas?

    Thank you very much!

    Hi Jared,

    I use indeed a door AND external as described in the thread.   Further research actually led me to discover that "you can't have two analog input tasks at the same time" of this thread:

    http://forums.NI.com/T5/Multifunction-DAQ/multiple-analog-inputs-by-multiple-digital-triggers/TD-p/1...

    So I had to build a circuit to convert my analog signal into TTL signals (for the release).  I then AND'ed the two signals in the same was as described in the thread mentioned above.

  • Golden Gate

    Hello

    I want using Golden Gate for level schema oracle to oracle replication replication (any object in the indexes, tables, triggers, procedures of plan...)

    I have a scheme called dds1, this scheme a lot of objects. Please guide me how to implement the initial load of this objects and then start the replication?

    Please guide me step-by-step:

    1. install the door gold on both sides.

    2 ......

    3......

    4.....

    Help, please.

    Hello

    Schema level replication means, all objects in the schema which is

    configured for replication OGG, will be replicated from the source to the target.

    including the procedures, functions, packages, etc. To do this, you must activate

    DDL replication. DML replication will not satisfy this.

    Once again for the DDL replication, you must use DDL ARE MAPPEES parameter in

    extract and Replicat parameter files. This setting will capture and

    replicate all the DDL operations located on the side of the Source for the

    particular mapped schema.

    For more details, please see the links below.,.

    1 installation and Configuration of DML-

    http://www.Oracle-SCN.com/installation-and-DML-replication-configuration-of-Oracle-GoldenGate-11g/

    2. the DDL Configuration-

    http://www.Oracle-SCN.com/DDL-replication-configuration-of-Oracle-GoldenGate-11g/

    3. What is the initial load-

    http://www.Oracle-SCN.com/GoldenGate-initial-load-techniques/

    There are several types of Oracle GoldenGate initial charge and you can also use

    EXPDP / IMPDP for synchronization at the start of the source and the target. But as objects

    procedures, packages, functions, etc. must be initially created in the

    side of the target.

  • that triggered him find my iphone application?

    recently, many of our devices have been hacked, my ipad is not damaged or stolen data. No access to my account. My ipad has never left my house. I was not raised him find my iphone app. I have even use icloud as had long since forgotten my id for it. How ever, I have all the details of the user appropriate all the correct passwords and have managed on the basis of work on my icloud identifiers. But still not get my unlocked ipad because apple has placed a lock of activation. Whenever I tried to cancel it with my security questions, he asks my birth date, but the web browser lets you enter the jj/mm but not YYYY so how can I possibly unlock with questions, and the e-mail address associated to the recovery no longer exists.

    An employee of apple care told that I must have my p.o.p. for them to do anything, and it's a joke because I bought it in cash and the retailer doesn't keep records of cash transactions which, to save.

    Why should I lose my ipad although I did absolutely nothing wrong.

    Please, someone tell me there is a way to solve this problem.

    I tried to address this issue for months.

    How will I know when and where to find my ipad app has been triggered?

    Unfortunately there isn't an easy way to solve what you describe.  As the mentioned Apple employee, you will need to provide proof of purchase to remove the lock of Activation (this is a security measure to ensure that the right person calls for its removal).

  • Automation not triggering Homekit

    I'm really loving the new application Homekit in iOS 10. I think it is much better than the app of hue of Philips I used to control my lights at home. However there seems to be something wrong with the function of automation. Or if Miss me just something, in this case, I'd appreciate any help I can get.

    My configuration is:

    • 4th gen Apple TV acting as a hup homekit
    • 1 Philips Hue bridge
    • 4 white tinted Philips bulbs
    • 1 Philips Lightstrip of Hue
    • 1 iPhone and 1 iPad Mini using Homekit app to set scenes

    I have several scenes set up and using automation functionality, I use the following schedule

    • Good morning - All 4 white bulbs and lightstrip on at 05:30
    • Lights - all the lights from 08:45
    • Afternoon - all 4 white bulbs and lightstrip on at 14:30
    • Evening - 3 white and lightstrip bulbs on at 19:00
    • Good morning - all lights except lightstrip off at 22:30

    The problem is that the timers don't always trigger. As far as I know, the afternoon lights, evening and good night controls work fine. But the automation of the morning never seems to trigger automatically. When I try to debug the morning and playing with time and wait and see, it will sometimes trigger, sometimes not. And then I wait again the next morning and it does not fire. I even put a light in 05:00, half an hour before good morning, to see if it helped, but it didn't.

    Does anyone have any suggestions as to why automation in the morning won't turn on?

    Hi Arthur,.

    I have the same problem as you. The triggers appear to respond inconsistently. The worst is the one from the Sun which is added when it is already dark. Apple should add the ability to take some time before the sun goes down. My Apple tv is always on and I also used an ipad as a hub. Have you found a solution since you post your question?

  • HTML5 triggers ALSA incredibly high volume video

    On the latest nightly of Firefox when viewing YouTube videos, or any other site that offers html5 video, my sound is automatically triggered, about 50%, or 100%. This happens with both h.264 and VP8. I tried in safe mode and with a new profile, does not. I have alsa and pulseaudio, but if I open a YouTube tab and watch alsamixer, he will jump from there where I got 100% as soon as the video starts to play.

    I tell myself that I will probably need to post a bug report, but I thought I'd try here everything first.

    I put "dish-volumes = no" in my etc/pulse/daemon.conf. He's not big, but it solves the problem for now.

  • Volume is out of control (gets his "own life") - triggers ATV volume goes to the maximum or minimum in a matter of a minute.

    Hello

    I come from Apple TV.

    When turning on our ATV volume it triggers that our volume of receiver Denon drifting slowly to maximum or minimum-, it takes about 1 min to do this.

    Tried to connect directly to our Denon receiver and our Sony TV ATV. Problem happens in two configurations. I tried different options to turn off the smart controls which offers the latest HDMI - ATV standard both our TV (for example, disable the automatic volume control).

    By turning the ATV and the new (menu system) will stop the problem for awhile - but same problem returns after 1 to 5 mins.

    I spent 8 hours in the last days trying to make it work. Looks like a bug in the SW of the ATV? (i.e. Disabling smart control of ATV does not take effect).

    Desipite being impossible to use, I don't want to damage my 20K speaker system. I am close to my unit back and get a Chromecast instead.

    Any help to fix this would be appreciated!

    System: Apple TV Gen 4 + Denon AVR 2313 + Sony KDL 60w605 all the connected HDMI (and 3 other units that work very well).

    Sounds like a defective remote control.  With HDMI control off the coast, it seems possible, that the remote control is to turn off the IR signals directly to the receiver.  Try to cover the distance before or the façade.  In any case, I would return the unit.  During the test leave in the main menu and just look at the level of the volume on the receiver.  Do not play anything to avoid overload problems.

    Post your receiver model number.

  • Portege M200 - stylus triggering random buttons

    I recently bought a Tablet Multi Dock for my m200, but having the problem the buttons on the stylus on the right side of the screen to get randomly triggered during normal use when it is docked. I tried the new drivers for my USB mouse, I tried different USB ports, but it still happens.
    Any ideas?

    Hello

    It is not easy to say what may be the problem. I don t think that it is a usual problem and I don't think it is the problem of USB.
    It will be interesting to know if this happened always or just at the time when the device is connected.
    Furthermore, I have recommended the Utility and Mobile Extension accelerometer update.

  • Qosmio G40 - 10F down arrow is triggered by itself

    Qosmio G40 - 10th down arrow seems to trigger by itself while booting and while I view web pages.

    The problem surface when I was accessing the web pages at the start of the screen to scroll down by himself.
    Before, I thought that the button may be pressed hard but when I looked at the issue through a senser key application to test what triggers the down arrow key press on and found that two or three other keys trigger arrow key down automatically.
    namely, in arrow, i key, key k, function keys.

    But when I press ESC or Page up/Page down, scrolling stops for a while but starts to make arrow down by itself again.

    I have re-installed and restored the entire operating system to the date of loading of the factory and the problem solved only for a few minutes and the issue is back.

    I am convinced that this is due to software problem and not a hardware problem, as the key works fine for a while and after a few minutes, begins to trigger arrow down permanently.

    Please advise,
    Thank you.

    Have you tried an external USB keyboard and then you have the same problem?

    I think that it s a hardware problem and the keyboard must be exchanged, but that before test with an external keyboard.

  • How to activate Noise Gates in GarageBand?

    I use GarageBand 10.1.0.  I want to use a Noise Gate, but the option is grayed out and is not clickable. See picture attached.  I guess I have to load a plugin to enable this feature.  Can anyone advise how to do this in the latest version of Garageband?  FYI, I found instructions for older versions of GarageBand which concern 'by clicking on a location empty', but I do not know how to translate these instructions for the new screens in the latest version of GarageBand.

    Appreciate the help...

    Noise gate will be automatically activated, if some effects have been applied to a track.

    She works for instruments that use effects such as the simulation of distortion, overdrive and amp.  See:

    Prevent noise effects in GarageBand - Apple Support

    Disturbed by the noise in quiet passages of your recordings of real instruments? No problem - meet suppressor of GarageBand.

    Overdrive amp and effects like distortion simulators involve the amplification of the input signal of the real Instrument. This amplification can also push otherwise imperceptible noise instrument and the background. The noise gate can prevent these unwanted sounds at low altitude in the effects

    To reduce noise in a silent passage:

    1. Select the desired range.
    2. Click the icon of headphones for the solo track.
    3. Open the track info window.
    4. Expand the window you will see "details".
    5. Click the box of the grid.
    6. Start playing the song.
    7. Adjust the slider of the door so that the noise disappears from silent passages, but the instrument is not still normally elsewhere.

    I can not give all tracks voice, but for most pieces of guitar and bass tracks is already active, as soon as I create the track.

  • The NI PCI-5124 scope with 2 triggers

    Hello

    I would like to ask about the trigger for starting and reference with PCI-5124.

    I found a sample VI on the following link, but it does not work as I expected.

    http://zone.NI.com/DevZone/CDA/EPD/p/ID/2998

    VI 'start_and_reference_trigger.vi' can detect the outbreak starting and reference in my system, and they begin data acquisition.

    He starts data acquisition when both start and reference triggers are entered.

    However, what I would do is:

    1. sampling at 200 MHz with a 1500 with a single channel record length.

    2. receive the signal to start (i.e. 50 Hz)

    3 receive the reference signal (i.e. 50 kHz)

    4. for each trigger reference, I would like to acquire the data, i.e. data of 1500 for each 100 trigger acquisition reference (not with the combination with the shutter release to start)

    Start trigger: _|^|_________________________________________

    Ref   trigger:______|__|__|__|__|__|__|__|__|__|__|__|__|__|__|____

    ^    ^    ^    ^   ^   ^   ^   ^    ^    ^   ^    ^    ^   ^

    hours of relaxing I want to acquire

    Trigger channels I use are:

    Start the trigger: PFI 0

    Trigger for Ref: PFI 1

    With the sample VI 'start_and... '. ", I found that it acquires when the two begin and trigger reference comes and data collection was only after the release of a single reference.

    I hope my explanation is understandable and I can have a solution soon.

    Hi Tom,

    This example configures a trigger starting and reference, but only for a single record. It is inside a loop, so it will continue to require a trigger start and each record. According to your description of the problem, you want to make an acquisition standard multi-record of 100 records, but you want to implement a trigger to start at the beginning of the acquisition. "' To do this, you can simply open the example of shipping"niScope EX Multi Record.vi"found in the example Finder LabVIEW or by browsing in your Start menu programs" National Instruments "NOR-SCOPE ' example. You need to add the property node to define your Trigger source begin to be PFI 0, but other than that, it should work fine. I have advanced and created a simplified with the trigger Start implemented, attached below. I hope this helps!
