• HDMI is not send the signal on external monitor once the laptop awakens from his sleep

  I have my TV as a second monitor for my laptop. I connected via HDMI. Once I leave my laptop a little past in mode 'sleep' and the screen loses the connection. Once I wake up the laptop, the monitor is not turning back on my desktop. It remains off. I disconnect and reconnect the HDMI and it does nothing. During this operation, my laptop screen flickers as when he connects to it, but nothing happens. My TV does not receive the signal, but the laptop says it's connected. What can I do to fix this? Thank you

  PS. I have to restart my laptop each time to allow to work my external monitor.

• Pavilion dv6: Notebook does not receive the signal of 5 GHz

  Hi, recently I bought a new modem router with the capacity of 5 GHz. After the establishment of the net, my laptop does not have the SSID. Other devices receive the SSID and connect to. How can I check, discover and recognize the net working at 5 GHz

  Hello:

  Most likely your laptop is only a single wireless card band (2.4 GHz) (model ending in bgn suffix).

  Virtually no consumer class computer laptop HP made at the time came with a wireless card dual band (model ending in abgn or agn suffix).

  Even those made today... most of them still have cards of single band.

• Wireless LAN does not receive the signal from the router

  Yesterday, I bought a toshiba satellite pro L10 and it's got wireless, but for some reason some can't find any network even when I'm in the same room as the router. What can I do?

  Hello

  Well. First of all, check if the wireless antenna is turned on. Check the switch on the side. In addition, with the FN + F8 key combination, you can switch between the Bluetooth card and wireless.
  In the next step you should check the wireless network connection properties

• ConfigFree does not show the intensity of the signal

  ConfigFree works properly - except that the Wifi strength is displayed at the highest level for all sources, regardless of how effective. (as it is deducted from the source location and the signal strength indicated by the utility windows)
  I.e. all access points are on the inner ring.

  I am running Vista on a Portege M400 with Configfree version 7.0.0.24 and Intel 3945abg driver 11.1.0.86. I got the Intel proset utility loaded, but they would not show the signal strength at all. So I unloaded it.

  I tried rolling back the drivers for the driver Wifi and Configfree with no change in behavior.

  Any suggestions at all would be welcome.

  Rod Laird Australia

  Hello Rod

  I use Vista on my Satellite last Vista designed ConfigFree utility, but I never noticed the signal WIFI is displayed there. Can you please explain exactly where this signal must be shown?

  When connected to WIFI, you can see the small symbol in the task bar but this symbol belongs to Vista and the symbol of the strength of the signal is also visible in Vista network and sharing Center.

  Sorry but I do not see this symbol in Configfree directly. When my laptop is connected to WIFI all I see in ConfigFree is connected (blue) status and the connection between PC icon and black (marked as G) WLAN. It is also interesting that the small blue animation moves along that black line.

  All that s!

• When I connect my computer to the Netgear router, they do not seem to recognize the signal from the modem. I have to run each device directly to the modem (one at a time) for internet access.

  I have both a laptop and a desktop computer and use a modem wired high-speed internet.  I bought a router "Netgear" 5 port so that I could have both online at the same time, but when I connect my computer to the router, they do not seem to recognize the signal from the modem. I have to run each device directly to the modem (one at a time) for internet access. It gets very tedious, please help...

  Original title: router does not work...

  Hello

  Welcome to the Microsoft community.

  I see that when you connect multiple computers using the Netgear router, it does not recognize the signal from the modem.

  You must contact the ISP to verify if they can help you with this question.

• Data not appearing is not in the worksheet

  Hello

  I'm looking to acquire three signals in a single spreadsheet file. Two signals are acquired with the NI USB DAQ6001 and the other signal is a multimeter across a GPIB acquried.

  Whenever I record the PDM file, a set of signals will save. I'll have to either all resistance measurements and only the final measures of the DAQ OR all the signals DAQ hardware signals and the last measure of resistance. I've included a photo of the Panel front and block diagram.

  Thanks in advance!

  When you pass the wrong dynamic data out of the while loop, you only pass the last result. I would suggest you convert data into something concrete that automatic indexing will work in the same way you do the meter.

• DAQ Assistant does not export the values on the scale

  Hello all-

  Potentially stupid question but here goes: I'm using the DAQ Assistant to read in 4 analog input voltages, continuous sampling acquires data at 10 Hz 1 point, using LabView 12 on a machine with an acquisition of data USB-6341 simulated device (because my office is more comfortable than the lab!). I want to change the first two signals of voltage to temperature and humidity, respectively. I used the «create a new...» "in the 'Custom Scaling' drop-down in the"Voltage configuration"tab for each of these channels, named gave the slope and the intercept at the origin for the respective linear scales and click OK."

  When I test the code - and yet once again, I'm not on a machine with a 'real' DAQ system, I use a simulated device, and it seems that NEITHER MAX generates a sine wave of long period with little noise on top for this - I do not get the results on the scale of my 'signal', I get the raw tension. (If you run my code, I will join, the Relative humidity must be between 0 and 100 and temperature-40 to 60, is not 0 to 5, for example.)

  So, what happens? Is there some flag or setting that I missed? The scaling only works on voltage data 'real' of a 'real' instrument DAQ, instead of a simulation (which is why I mentioned twice!)? I have to do something in NI MAX as well as Labview?

  Thanks for any help you can give.

  Simulations devices will not respond to custom scale.  They are just supposed to allow you to configure your device without errors when you do not have the unit on-site.

  "NOR-DAQmx simulated devices create a noisy sine wave to all the entered analog." Simulated data other set-up is not available at this time. »

  http://www.NI.com/white-paper/3698/en

  They generate a sine with an amplitude equal to half of your specified input range.  If you want to work with simulated data that would be more realistic for your application, you could write a VI to generate the data and have a business structure to manage both "simulations" and "real", then you could switch back depending on whether you have access to the material.

  I just checked this with a PCI-6254 I install and simulated a PCI-6254.

• In Labview 8.5, what happens if the input signal exceeds the scope of the signal defined by the DAQ Assistant?

  Hi all

  This should be a pretty simple question, but I can't seem to find the answer online and currently do not have the functionality to test this:

  I'm using LabVIEW 8.5 and have a VI that imports data from sensor through the DAQ Assistant. In the configuration tab, there is a range of signal input. What happens if my sensor exceeds this range? I get a warning? The default value is the maximum (or minimum)? I was interested in writing a code to display an error that I approach the limits of this range, but did not know if I also need to include code to display an error if the scope is exceeded as well.

  Thanks for the help,

  Tristan

  Hello, Tristan,.

  The behavior depends on the selected range and the device you are using.

  If you are using a device with a single input range is valid, we will use this range, even if you set a smaller minimum and maximum in the DAQ Assistant.  So, if your device only supports ±10V and you set the range to ±8V, you will still continue to get valid data after your top sensor 8V until what you approach 10V.  When you reach the limit of the extent of your device, the output will be 'rail', and simply return the maximum value until the signal is less than the maximum value again.

  Note: A device that is nominally ±10V usually has a go-around (such as ±10.2V) which are usually specced in the manual.

  However, if you use a device with several ranges of entry then things become more complex.

  NOR-DAQmx player will choose the smallest range that entirely covers the interval you choose.  For example, suppose that your device supports the following input range: ±0.2V, ±1, ±5V, ±10V and you choose 0V - 3V as the range in the DAQ assistant.  The NOR-DAQmx driver will focus on the input range and the list of the entry lines that your hardware supports and choose the smallest encompassing the entire range that you set.  This would be the ±5V, because this is the only beach that contains up to 3V.  Thus, all between ±5V input signal is returned and none outside this range will be 'rail' to the maximum or minimum value.

  We do this because using small beaches make more efficient use of the resolution of the ADC.  So, we try to use the most effective range based on what you ask without picking up a range that will make you miss data.

  Let me know if I can clarify it more.

• How to select the signals from the output of a DAQ assistant

  Hello!

  I am a new user of Labview 8.5 and I work with a USB-6210. I have two different instruments connected to the same USB device, half of the channels are used for the transducers of pressure where I only need reed and record data, while the other half are associated with TCD detectors where I need to perform an analysis of the signal to get and save the data. I'm in the first stage of construction the block diagram, once I have defined each of the signals that its correspondent of channel using the DAQ assistant, I need to select and separate the signals coming from sensors of pressure from those who come by the TCD detectors, before that I can continue to draw the block diagram. I am using the function select Signal, but I don't know how to do this. Can you get it someone please let me know at least in which manual, I can find a good explanation? I have read the getting started and the LabView user manual, but they have not been very helpful so far.

  Thank you!

  I fixed it. As you say, I had some mistakes in the thread, but it's working now. Thank you very much for your help! It was very useful.

• Two synchronized USRPs receive the same sine wave emitted by an another USRP, there is a phase shift random and obvious between the signals received from the 2 receivers

  Hello world!

  First of all, I use a USRP as a transmitter to emit a sine wave (the signal is exp(j2*pi*f*t)), and then I use the external clock to synchronize the two USRPs (Ref as PPS in are connected to the clock) as receivers. Receivers are in sync, and they are at the same distance from the transmitter, I thought that the signal they receive should have a nearly the same phase. However, in practice, the phase shift is big enough, and this problem really confuses me.

  It's the received signals of 2 receivers.

  Yes. What you observe is expected.

  Near the bottof of this document read the area 'alignment Phase vs Phase coherence '.

  http://www.NI.com/white-paper/14311/en/

  And also, for the alignment phase, see the following 'Angle of arrival detection with NI USRP '.
