start the acquisition via a digital triggering that receives a WEAK signal?

Trigger on falling edge, but not low.

  • Airport Time Capsule: Suspected of weak signal

    Hello

    I have 3 Apple wireless devices all. The main router is the ATV, followed of an Airport Extreme, extending the network and a former Airport Express, also the extension of the network. Briefly, it is a three-storey house, on the first floor of which is a daylight basement (windows and doors on three sides), then the second and third floor (all wood of the frame).

    I'm almost completely Mac/Apple-centric (my son except for the PC game), there are 6 Mac (PPC and Intel) and 4 iPhones on the printers network every day, matching, smart TVs and casual with a device visitors or 2. Generally, there is no connection problem apart from the complaints unfounded. There are a variety of El Capitan, Yosemite, Leopard, OS 9.2.1 and iOS operating systems. Computers are my MBP to 2008, two MacBooks circa 2010, 1 iMac (circa 2010), 1 lime iMac 400 has PPC G4 MDD and iPhones - 5s and 6s (2 of each).

    I studied this weak signal suspected by the search for possible answers on the internet, try to use various applications to diagnosis Wi - Fi and browse the various parameters of the airport. I was not able to "find" a smoking gun or even a reason suspected for the signal is so poor. "So poor" refers to my dissatisfaction with our signal coverage - my expectation!  It is perhaps as good as it gets and I have too wait.

    The layout has my ATC in my office, ground floor, the west wall of the House and approximately 4 ft above the ground. The AExt (from ATC) is through an open door and a flight of stairs and on the ramp (half wall). If you stretched a string directly between ATC and AExt would be 16' - 20'. The AExp bounced around, but currently it is in our gym, which is part of the structure of individual garage. The AExp is approximately 45 ' - 50' of the AExt and 65' or from the base (ATC). My goal is to explain the variety of signals.

    I'm not the most scientific. To drive off the coast, I don't understand why there are 4 WiFi signals reported. 2-5 Ghz and 2 to 2.4 Ghz. "The only basis ' creating a wireless network" is the ATC, the other two are "the extension of the network. There are 2 reported BSSIDs and I forgot how to determine who is what hdwr.

    Walk with a MB and it is Wireless Diagnostics app, it seems, most of the signal issues are explainable. One unexplained is when I get out the MB to the gym, the signal "through the roof" - it probably doubles in strength, and that's where the Express is maybe 60' of ATC. Sounds good, but why, when I go back to ATC, the fact the signal drop in half. I want to Express signal overall. I guess the Express to be the weak link, but of course does not appear like this. My main computer, the MBP, sits 15' and at glance of ATC and gets that weak signals - I guess that it could be the Airport card in the MBP, but I'd like to think not, that I have no way to test it. I'm sure that all this has to do with the 4 signals being broadcast and the differences between networks 2.4 Ghz and 5 Ghz.

    So, why is my best farthest signal from the router (ATC) and why is it the MBP of low signal (MB too), the nearest router. Oh, I have no neighbors to 500' or more. Sorry for writing a book.

    When you extend a wireless AirPort network using intermediate connections wireless base stations, it is important to understand how fundamentally. So please forgive me if I go to the places you already know.

    Extended wireless airport works wheel - as with the base station extend over the hub of the wheel. Each of them extending base stations would be on a spoke of the wheel. With the new 802.11ac 802.11n base stations, you can not extend linearly. For example, in your game both the extreme and the Express would be on another spoke in the wheel, step along the same spoke. Make sense?

    That said, the station of further base your Express, would have a harder time getting a signal strong enough to expand it, while extreme may not have this problem. Basically, this would explain the gap between the quality of the signal between these two base stations.

    I wrote an an airport users points to try to help to how to best place a base station that extend. It may be useful.

    To drive off the coast, I don't understand why there are 4 WiFi signals reported. 2-5 Ghz and 2 to 2.4 Ghz. "The only basis ' creating a wireless network" is the ATC, the other two are "the extension of the network. There are 2 reported BSSIDs and I forgot how to determine who is what hdwr.

    By default, each of your simultaneous dual band base stations provide actually two wireless networks; one on the 2.4 and the other on the 5 GHz bands. Base stations extending each of these repeat if they are in the range. Note that the higher frequency band (5 GHz) would have a harder time penetrating objects, such as walls, ceilings, etc. and it is basically only usable in the same room. I'm guessing what to do in distance between base stations, the extreme is able to expand both networks, but the Express (especially, if it is a model of generation 802.11n 1) extend one or the other.

    For routers to Apple, the BSSID is the MAC address wireless base station itself.

    To each base station that spread, the level of the signal from the base station can be high, but real bandwidth of the signal will be the same as what he receives in this place. Yes, you can see a high (full bar) signal level, its ability to transfer data will be reduced because of this limited bandwidth. The key is to place the base station that extend to a resort beach it is the extension to get the specific width of possible higher bandwidth SNR. It is covered in the tip that I quoted above.

  • Weak signals of TV on my Qosmio F25

    Hello
    I just bought the Qosmio F25 and I put on the antena, but all channels are coming in a very weak signal and the picture is very distorted, and is therefore the audio. Why do you think it is happeing. What should I do to get better signals and a good image in a way?

    Hello

    It's not easy to say why it happens.
    What software did you use? Media Center or Qosmio player?

  • Weak signal of blackBerry Z10 after the latest version of the OS

    I just updated my OS (10.1.0.4181) a few days ago. Then I noticed abnormalities. First of all, my phone has become weak signal. I can't access the internet as fast as I had before the upgrade. Then, my bbm notification alert keeps lighting even if there is no incoming message. I tried to turn off bbm as part of management of the hub, but it's still lighting.

    Please do something about it. I enjoyed my quick navigation and cats so much before the upgrade. But now I have to wait my message to be delivered for several minutes. (

    Hi Lulu,.

    When you reinsert the battery are displayed notifications still lodged in the hub and it only happens with BBM messages in the hub?

    Thank you.

  • Satellite L755 - 1 DR: WiFi weak signal even on top of router

    I recently bought a satellite L755-1 DR and everything is ok, but the WiFi is really weak. All my laptops to get you the best wireless signal and my new computer laptop even unable to connect to the router, and if it connects with success it only lasts a few minutes. When im even in coffee with my friends, they have good signal with their cell phones, and I can't even reach a Web page.

    I ve already installed the latest drivers for the Atheros AR9002WB-1NG wireless network card and it's always the same. I tried to reinstall the drivers, Turn off all applications and services and keep only those of microsoft windows, and it is impossible to get a good signal. I ve changed the settings to the Maximum in each Power Saving Option to save energy, and still nothing has changed.

    I've seen some people claiming that the problem is not well connected wireless card, but I can't open my laptop and losing my warranty, and I don't want to send it to the warranty since I need the laptop for work.

    Y at - it someone with the same problem? or a solution?

  • Timestamp of the external Signal triggered using the PCIe-6351

    Hello

    I use a PCIe-6351 to acquire externally triggered data.  My block diagram looks almost exactly at this link in the section A. Posttriggered Acquisition with a digital start triggering:

    http://www.NI.com/white-paper/4329/en

    As you can see he is a straightforward acquisition.  My trigger signal is on PFI0 and it is supposed to occur at regular intervals.  However, I started to suspect that it varies in time.  For example, if this is supposed to happen every 2 milliseconds it can range from 1.9 to 2.1 milliseconds.  Is it possible for DAQmx record the time at which each trigger occurs?  I realize that it will not be synchronized with the time on the PC, but as long as I can have a time stamp of each trigger I can subtract each time individual time of the first condition for the time between triggers.

    Thank you!

    Steve

    MR. O,.

    Thanks for the reply. My system is set up to acquire many points of data at a relatively fast pace, so I their stamp on the data acquisition card and only download on the PC once the acquisition is completed. My understanding is that writing to file measure vi set a timestamp whenever he writes to the file - not for each individual data point. Is this correct?

  • Power of the weak signal with my wrt54g

    My wireless router has been uneven, since my cable company installed a new internet cable modem.  I powercycled several times, downloaded the new firmware, rebooted and still have problems.  Lately when I finally get on the internet with a wireless device, the signal is very weak.  It is low on my iphone on my Mac laptop and also on my Samsung Bluray player.  Lately a window never ceases to appear when I'm watching netflix who says my bandwidth is too low, even if he works very well for 2 months.  Is my router obsolete?

    No, it is recommended to have security enabled. Does affect your signal strength when you activated? If this is not the case, go ahead and re - activate.

  • Help with Aironet 1252AG-E-K9 and weak signals

    Hello

    I have an AIR-AP1252AG-A-K9 and a LOOK - ANT2506 2.4 GHz omnidirectional antenna. First of all, I am new to wireless space...

    I have to connect to a local network with a PC which is 280 meters, only a single PC. We have the Aironet connected to the switch with this antenna, but the signal is very weak, I am doing wrong? or what I need to do?

    I activated the SSID and Radio0 - 802.11n2.4 GHz, give the IP address and I can connect my laptop... but the signal is so weak and we need to get the signal to 280 meters!  ;-(

    Thanks in advance...

    195 m is too much for any client.

    It must come with an access on each side point and powerful antennas. That's all.

  • EM330 weak signal

    Hello

    I bought a t-mobile em330 in Glasgow a few weeks ago. I took in Uruguay (South America) and unlock via imei in order to use the phone with my contract of movistar (telefonica). The phone works but the signal is very weak. Actually, I loose signal all the time and the battery discharges quickly trying to keep the phone connected to the network. The problem of any ideas of what can be?

    Thank you

    David

    David-

    • Unlock the phone the phone does usually not cause a problem. It's the physical limits of the phone which generally present questions or if there is an incompatibility of network about a feature.
    • The phone will have only network when 1900 is available. If you have 850 and 1900, then the phone could go on whichever is stronger.

  • Weak signal with airport Extreme

    Hello, we have an Airport Extreme tour in our condo. The signal is that two of our rooms is low. Is there a way to increase the signal? Not Apple or any other extenders of sale of business or boosters?

    Thank you

    Another extreme airport would be the perfect match to extend the signal of your "main" AirPort Extreme, but an AirPort Express pourrait point be good enough for your application, if the budget is limited.

    Ideally, the second airport would be located in the middle of the area where you need more wireless signal strength and then connect to the 'main' airport using wired Ethernet wired, permanent.

    It is possible to have the second airport to extend the first using a Wi - Fi connection... IF... the second airport is where he can receive a strong signal from the first airport.  A good location is at halfway between 'primary' airport and the area that needs more wireless coverage.

    Remember that when you extend wireless like this, there is always a loss of about half of the potential wireless speed on the network, then the result will be a network with the best range, but reduces the maximum speeds.

    The more you have line of sight between the airports, the network will be operated. Or, another way of saying the same thing, is the 'extension' airport to expand the speed of the signal it receives. It can make the stronger... wireless signal but can't go faster.

  • Equium A300D - power of the weak signal on built in wireless

    I've had my Toshiba Equium A300D - 13 X for a few years now. I also have sky ADSL broadband for a few years. My signal from the router (netgear) until a couple of months has been very well. The router is located in my hall, and I use my laptop mostly in the lounge which is through a wall, 3 or 4 meters. Strength showing on the wireless icon in the tool bar used at least 4 or 5 bars but now the best I have is 3 bars force and my connection is variable with Web pages take longer to load.

    If anyone has experienced this? Could there be something wrong with the internal wireless antenna?

    Any advice would be great.

    Hello

    Have you changed anything on your phone (settings, updates), router (update firmware, settings), or perhaps in the region (placed a device which can interfere with the signal)?

    Hello

    Usually, you can try to change some settings in Device Manager-> card WLan-> properties-> Advanced tab

    In my case (I m using Intel WiFi card) I could find a few different options. signal strength, channel, standard Wlan.
    Try to use a single standard like 802.11 B or G, try an other channels etc.

    I filter a signal of amplitude of the 0.2 Volt connection. It consists of pickup and noise of the line. How to do? Is the software filters are enough or I have to design a filter material?

    Hi sukhiray,

    If you have less than the full version of LabVIEW, there are several software filtering options available in the category of Signal Processing. You can configure your thresholds and the order of the filters and choose between the different types of filter. The choice between hardware and software depends on your needs and signal.
