Fluctuation of the potentiometer signal

• Fluctuations of the Wi - Fi connection!

  I bought a Toshiba Tecra M3 1.73Ghz with 802.11bg wireless in July of this year and it was working fine until about a month. At the start, my wireless connection saves 58MBps (and the "excellent" signal strength) but within 5 minutes, which drops drastically to 24 Mbps and even a skinny 1MBps sometimes. I also note that it disconnects and reconnects by itself, by new windows pop up notifying me of new connection frequently.

  I checked my wireless hub and there is no problem with him. Indeed, my roommate have no problem with connection on his Apple G5 speeds. I also tried the obvious solution to move my right cell phone next to the hub, but that did not affect the connectivity.

  Download speed fluctuates constantly and I cannot play games online such as counter-strike: Source, because I constantly disconnect and hang with my ping from 30 to 9999.

  Is it a hardware problem or is there a software problem that I'm missing? If so, where I can take my laptop to get the sorted material?

  Thank you
  Ben

  Hello

  In my view, it is certainly caused by hardware. In my opinion, you can swap the wireless card and then you should be able to use the WiFi without problem. If any of your friends have PCMCIA WLAN card, you can test it.

• Why my MB Air decreases the wifi signal

  My 2012 13 "core i5 MacBook Air running different operating systems will remove the wifi signal and it is getting worse. someone at - it a reason why?

  How your MacBook Air running different OS version? However, the Wi - Fi signal fell to each version?

  This always was a problem or just started to happen? Up to now, what did you do to try to solve?

• After updating my iPhone 6 (9.3.4) the WiFi signal becomes very low! I did everything, but the problem does not stop! I don't a not update my other devices & their very good WiFi signals. Please help me solve this terrible problem...

  After updating my iPhone 6 (9.3.4) the WiFi signal becomes very low! I did everything, but the problem does not stop! I don't a not update my other devices & their very good WiFi signals. Please help me solve this terrible problem...

  Here's a tip for the user on the problems of Wi - Fi. Suggest from the top and bottom. Maybe one of them will help you.

  (1) restart you device.

  (2) resetting the network settings: settings > general > reset > reset network settings. Join the network again.

  (3) reboot router/Modem: unplug power for 2 minutes and reconnect. Update the Firmware on the router (support Web site of the manufacturer for a new FW check). Also try different bands (2.4 GHz and 5 GHz) and different bandwidths (recommended for 2.4 to 20 MHz bandwidth). Channels 1, 6 or 11 are recommended for 2.4 band.

  (4) change of Google DNS: settings > Wi - Fi > click the network, delete all the numbers under DNS and enter 8.8.8.8 or otherwise 8.8.4.4

  (5) disable the prioritization of device on the router if this feature is available. Also turn off all apps to VPN and retest the Wi - Fi.

  (6) determine if other wireless network devices work well (other iOS devices, Mac, PC).

  (7) try the device on another network, i.e., neighbors, the public coffee house, etc.

  (8) backup and restore the device using iTunes. Try to restore as New first and test it. If ok try to restore the backup (the backup may be corrupted).

• Satellite C850D-11 q keep loses the WIFI signal

  Toshiba Satellite C850D-11 q BT Hub 4 Realtek drivers

  I lose the wifi signal at least twice a day. Same message to loose / broken cable and reset the wireless card. Realtek has informed me that I have the latest drivers. The present is Realtek RTL 8188CE Wireless Lan 802.11n PCI-E NIC hub is new. With the help of BT, I now use the 5 GHz as the hub is on a shelf just below the laptop.

  I don't know what to do else and thought someone here can get an idea of what to do next apart from the change of servers!

  Thank you

  I wait too long? Has decided to search for updated drivers. Goes up to 8.1 not 10.

  Then decided to download the manual. Informed, there was one, but there is no way to access it. Message received this laptop modified 10/15/15. Well thank you very much for this. Message also States that "with this tool, you will get urgent information about updates for your computer. I clicked... Web page could not be found.
  Large. Because buying a new laptop, but it will not Toshiba, that's for sure.

• Costume measurement OR for Mobile/Fixed WiMAX 1.0, is there any optiion to activate PUSC or AMC for the generated signal?

  Hello.

  I use a VST OR to generate the WiMAX signal. I installed NO measure costume for Mobile/Fixed WiMAX 1.0 on the calculation. But I can't find any option on the front panel of the combination of the generation to enable AMC or PUSC for generated signal. This feature exist at all?

  Thank you.

  Hello sam2013ni,

  That's all I see for AMC and PUSC. Look in "box Type".

• Acquisition with USRP 2953R of the GPS signal

  Hi all

  How can I configure a 2953R USRP receive GPS signals? I have an antenna VERT900 connected to the GPS ANT of the USRP port, but in the example VI 'niUSRP EX Rx with GPS', I can't reference this port in the field 'Active antenna'. I put only things like TX/RX or RX1 etc. Should what values I put in other areas as well? I know that the L1 band is 1575,42 MHz.

  

  Hello

  The example you posted shows you how to acquire an RF signal on the ports of the USRP with internal clock RF and sources of reference defined in the GPS.

  To make it work properly, you must have a GPS antenna connected to the Terminal on the GPS device and installed in a place that receives a good level of GPS signal.

  The other control of antenna on the schema defines the port on which to receive the RF signal.

  If you want to capture and analyze the signal GPS (RF) itself, you can tune into the front-end RF (carrier frequency) at the right frequency of GPS band and connect your GPS antenna to the RF port.

  You can use the simple niUSRP EX Rx continuous Async.vi in this case (but may not work due to the very low consumption of GPS RF signal)

• Cross spectral power and consistency of the 2 signals

  Hello

  I try to get the cross-spectral power and consistency of the two signals. I should be able to get this:

  "The cross-spectral power and consistency of these 2 signals have been calculated on a window (8.5 minutes) 1024-sample using the fast Fourier transform applied to the 3 overlapping of the panes of 512-sample in the window of 1024 consistency." In each pane, the data were the first linear straightened and with windows by using the Hanning (cosine) function before the calculation of the Fourier transform. The 1024 coherence window was so advanced by 256 samples (2.1 minutes), and the calculation repeated until all BDUS/interval of N - N series have been analyzed.

  We used the product of consistency and the cross-spectral energy to weight these 2 effects in order to quantify the degree of the hitch.

  I should get this chart type

  

  The RR signal I straightened before that trying to get the power crossed with sampling freq = 2. And I put 2 ways to get it.

  consistency too and later the product of the two. Im trying to get the spectrogram and watch later 3d like picture.

  I have attached the vi.

  Consistency is perhaps badly fixed.

  Thanks for the help, guys.

  Kind regards.

  you made a few mistakes, example en by overhauling it you can't do the segments overlap, that's why you should go with a loop and the creation of a subset (and this is why I suggested para window ASD)

  You must also set the indexing of the product release and do not concatenate, penny you released 2d end that you can use for 3d graphics

  FS in the mathscipt should also be in hz, not in seconds, I told you the last time (he is shown in the help)

• Desgning a VI that time / interrupts a film according to the input signal

  Basically, what I'm trying to do is to design a VI who plays or pauses a movie according to the signal it receives. This VI will be used with an EEG device, and what I want to do is play the movie if the signal exceeds a certain threshold, and it stops if this isn't, in other words a VI that responds to neurofeedback.

  As I don't have access to the equipment of the GET yet, I use a sine wave at the moment than the EEG signal in VI of the attachment in this post (which of course will be later replaced by waves of EEG recording), and what I want to do is to read the film if the signal is greater than 0 and put the film on hold if the signal is less than 0. Any help would be appreciated

  Kind regards

• NEITHER USB 4432 readable voltage i.e. the ASPM signal conditioning

  Hello

  For what I understood that the USB-4432 entries must read IEPE accelerometers report. Read a voltage signal conditioner of my sensor ASPM IE using the option 'IEPE-off with AC coupling.

  Thank you

  1. What if I use the 5th cahannel of
  4432 read the square wave pulse width, i.e. the digital signal
  tachometer using any function of sounds or labview software and
  Vibration Measurement Suite. If so, how precis specific will be read
  frequency (speed) compared to meter modules.

  Channel 5 is the same as the other channels of the 4432 except it lacks excitement IEPE and TEDS.  I can't really say how "accurate", it will be at a faster rate because of the delta-sigma ADC. Someone else wants to chime in on this one?

  2.
  Is available to trigger analog acquisition of digital triggering. If so, is
  It possibel to read all 5 channels togather in a single task.

  You're talking about!

  3.
  If there is only one PFI then is possible to trigger two
  different tasks, i.e. a task of 02 strings with front amount and
  a further task of 02 channels with the falling edge of the PFI even.

  There are 8 PFI lines, but can only be used on the device at the same time (it might as well be one PFI).  You must have all the channels you want to raise in a task and use one as the trigger for starting digital PFI lines. (i.e. 'no' ... have a stain on the front and the other on the falling edge won't work, a task only by digital triggering)

• can someone tell me why I don't get the graphic signals in seprate

  Hello

  I'm stuck with a fundamental problem, in fact I use NI USB DAQ 6212 with my labview8.6, what I do is to get two different analog signals to ai0 ai1 simultaneously and showing them on two distinct waveform graphs, I use the split signal table index and both to solve the problem, but it is always showing me what a signal on the two graphs instead of show me two different signals on the two graphs. can any body tell me what I'm going to do now, is there a problem with my DAQ hardware I brought just a few days ago, or should I include something in the software? criterion vi is attached.

• Count the edges of the 2 signals TTL (Heidenhain linear scale)

  Hi all

  This is my first post here. :-)

  Currently, I'm doing a VI to be used with a linear scale. The linear scale gives 2 TTL signals that have an offset of 90 °. The change in distance of the linear scale is given by counting the fronts and edges of the two signals. See the following image: Ua1 is signal 1 and signal 2 Ua2. You can ignore the other signals.

  

  Now, I want to count the 4 edges in order to translate the 2 signals in the distance. This means that I need advanced two counters for Rising-rising, Rising-Falling Falling Falling, falling on the rise for 2 signals. I tried to do 4 points two counters in LabVIEW but that of course does not work, because an acquisition of data can access the card TTL or I did it wrong.

  Once I have to handle this, I also want to understand the meaning.

  My card TTL: NI 9402

  My electronic Heidenhain interface: 100 IBV (http://www.heidenhain.com/fileadmin/pdb/media/img/598_160-23.pdf - also at the origin of the image)

  Hardware configuration: linear scale-> IBV (Elektronic Interface)-> NI 9402-> LabVIEW

  Signals: Analog 3-> 3 TTL-> OR 9402

  I hope I do not double post. Any help would be greatly appreciated.

  I used Heidenhain linear scales in many applications.

  As stated in the previous post, the output of your balance is as a quadrature encoder. Therefore, you must use an entry of the DAQ card counter to measure the position of the scale.

  The desired X 4 mode is done by the meter itself (not possible with some old maps of OR).

  As starting point, see measure angular Position.vi that comes with examples of LabVIEW. On your linear scale, change the type of the polymorphic DAQmx create channel VI CI linear encoder and etiquette of pulses per revolution at a Distance by pulse.

  Feel free to post back if you need further assistance.
