15454 Low Output Signal Power

Having a problem with the Bits timing output on pins A3, B3 and A1,B1 on the back of the Sonnet Shelf. Appears the output signal power of our 15454 is reading 1.30 which is very low.
Tried changing the LBO setting and it did not make a difference.
Need to now if there is a way to boost the signal power level up.
The bits timing ouputs are used to time our Motorola BSR (CMTS) for telephony. The problem the Motorola BSR's are experiencing is when you failover the SRM (CPU) to the Secondary SRM, you loose both timing inputs.
Any advice?

    If the Reset didn't work, you'll need to do a Restore.
    From iTunes, select the iPad and then select the Summary tab.  Follow directions for Restore.  You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finished, you will be asked if you wish the contents of iTunes to be copied to the iPad.

  • Slow WiFi transmission and low signal power (Airport Extreme extended by Airport Express)

    I am experiencing slow wifi transmission between my notebooks and my base stations and I am hoping someone can help me fix it.
    My wifi configuration is the following:
    1 Airport Extreme base station (acting as router, wifi "creator" and DHCP server)
    1 Airport Express base station (connected to Airport Extreme with a LAN cable, set up to extend wireless network)
    1 Lenovo T410 notebook with Intel Centrino Ultimate N-6300 AGN WiFi antenna (I will call this one "Lenovo"), connected to wireless network, running Windows 7
    1 MacBook Pro purchased in 2009 (I will call this one "Mac"), connected to wireless network, running Mac OS X Lion
    1 QNAP T209-II NAS, connected to Airport Extreme via UTP cable
    Airport Extreme (AXTRM) is creating a 802.11n wireless network with WPA2+PSK security with MAC address filtering. The other base station, Airport Express (AXPRS) is connected to AXTRM via a UTP cable. AXPRS is set to extend my wireless network.
    My first problem is low signal power. My appartment is 90m2 in size and is in one floor. It is a new flat with high ceiling and modern layout, meaning little walls, big rooms and wide corridors. Still my notebooks, iPhones and iPad can barely reach AXTRM when I am on the other side of the flat. This was the reason why I purchased AXPRS and placed it in the middle of the appartment. My notebooks are placed just on the other side of the AXPRS's wall (less than 1 meter of distance and a simple 10cm brick wall in between), yet signal strength is only at about 80% (measured on my Lenovo using Lenovo Access Connections tool).
    My first question is: Is it normal that in a 90m2 flat with not unusual obstacles, I need 2 base stations and even then have a rather poor reception?
    My second problem is even more disturbing. I think I have catastrophic transfer speeds via wLAN. It takes over 1 hour to transfer cca. 1GB of files (average size 8MB) from my Lenovo or Mac to my QNAP. My Lenovo is showing about 250kb/s transfer rate when copying files. At the same time, Windows 7 show connection speed 144Mbps. This mean about 18MB/s. I know these numbers are theoretical and that actual transfer speeds are lower. But hey, 72 times lower? Furthermore, if I copy files from my Mac and my Lenovo at the same time, transfer speed is slightly lower. On the other hand, if I connect my notebooks to AXTRM via LAN cable and copy files to QNAP, transfer speeds are a few megabytes per second.
    To make things even more confusing for me: if I transfer files from the internet, I get download speed at about 700kb/s, which is quite in line with my internet download speed. I don't understand why transfer speeds within my local network are so much lower.
    Therefore, my second question is: How to set up my base stations and my routers to get a decent wifi connection?
    I hope someone could help me. If you need any more information, just ask. Thanks!

    From my experience of setting up the Airport WiFi for family members and friends, I have learnt the following :-
    1. Airport Express is not as good as Airport Extreme, for being as extender, the difference can be quite a lot.
    2. There is always a dead cornor (bad reception) in a house
    3. Even moving the Airport Extreme / AE a few inches, the performance can be improved quite significant
    4. If possible, always choose 5G 802.11n than 2.4G, unless there are many thick walls.
    My suggestion will be as follows :
    1. Moving out the AEBS out of a closet, is a good idea
    2. Always try to locate the AEBS in the centre of a area, instead of the two sides
    3. Try to test the AEBS without an extender, and find the best location area (don't place on the floor, neither above 6 feet height)
    4. After finding a best location, set the extender closer to the AEBS, and then moving apart from it (check the performance after every move), it is better that both devices can face each other.
    5. I can't tell you the reason, and some people may not agree with me, the new 2013 Airport Exteme performance is better and may be is a good idea to replace your Airport Express, and use it to connect with your router, and old AEBS as an extender
    6. Some Powerlinks (in case you can't use a wired ethernet connection between the two devices) work and some don't work with Apple Airport products, therefore, if possible, have an option to return them to the shop if they do not match
    Good luck

  • How to create 2 output signal locked in phase from a one input signal

    Hi all,
    I have a case in which I want read in a signal analog input (voltage) from a photodiode, I want to create a 2 sinewave signal locked in with same phase as the input signal and output them as analog output to my 2 laser diode. the frequency of the input signal is low aroud 15 Hz , the 2 output signal i want to be  around 120 hz and 150 hz . 
    I am using USB - 6003 daq card.
    I have created a vi to see the input signal but I dnt know how to create 2 signal from the waveform generator locked in the phase as the input signal. I have seen a PLL vi , but dont know how to use that with my program.
    can any one tell me how to proceed.
    thanks

    Hi AnkitG,
    Here are a couple of links that might help you understand a little more how the PLL work and a way to synchronize the task to perform a PLL.

    Also, you should be able to find a lot of examples on how to accomplish the synchronization of tasks on the community, if you consider that the only consideration is that both must start at the same moment. 
    I hope, these examples might show you some useful concepts:

  • Output signal high at DIO lines of 7330

    Hi
    I am using Labview 7.1 with Ni motion controller. I am trying to detect the output signals at the auxiliary DIOports of the card using the attached programme in the NI example finder. My board ID is 1 (thats what was allowed by the programme) and I put port 1 , to check the DIO lines of it. I checked pin 10 (port 1-bit 0) and pin 44 (port1-bit 1) using an oscilloscope. The output is high at 5volts.
    I changed the DIO pin polarity switches to active low status but the output remains the same.I fiddled with the set and reset buttons of the programme, initialize the card but nothing changes.  Any idea on how to figure whats wrong? 
    Thanks

    Auxilliary Digital Output.vi ‏57 KB

    Hi
    Thanks for the reply. Sorry for the delay in response as I was on vacation. I tried your programme but the result remains the same. The output is always high.
    Max shows the card is working properly. It also shows the board type as 63. But the programme only takes in board ID as 1. How can set the direction using MAX and save the settings?
    I tried the write 1 point example programme on axis 1 ,line 1 and tested the signal on pin 44 and 42 (oscilloscope ground), and toggled the line but the output is high. But when I stopped the programme with the STOP button it gave an error message 70102 with a possible cause the setting doesn't match the line direction?
    The oscilloscope ground was firmly connected to pin 43 or 42 of the board for all tests.
    I appreciate your help.
    Thanks

  • Output signal distorted

    I have a pretty large VI which outputs high frequency signals to control some hardware and then takes an input from that hardware for image rendering.  My problem is that whenever I activate the imaging portion of my VI, the output signals become slightly distorted.  For example, a 1Hz sawtooth output doesn't ramp up smoothly but becomes slightly staggered.  This also messes up the frequency of the signal.  Does LabVIEW have problems outputting signals properly when another portion of the VI has a lot of cpu intensive processing?
    I am using the "Simulate Signal" block to create a 1 Hz sawtooth wave, 128 Hz triangle wave, and a 65,536 Hz square wave and outputting these signals through DAQAssist.

    Hi Laura,
    I went ahead and changed the 65,536 Hz square wave signal as the first input, but the three signals still do not output simultaneously.  Although the signals slightly change as I vary the Samples per Buffer and Cycles per Buffer, I can't seem to get a combination that is capable of outputting these two low frequency signals with my high frequency signal.  I would either get an error message about "DAC conversion attempted before data to be converted was available," or there would be no error message but the signal output didn't match the given specifications.  Attached is the vi with the modifications.  Presently, there is no error message with the given sampling information, however there is no square wave output at all, and the sawtooth waveform only shows a partial amount of the signal.  I had to make some slight modifications to the Waveform Buffer Generation vi in order to allow me to change phase, duty cycle, and offset of my square wave.  I don't think this would have any effect on the Cont Gen Voltage Wfm vi though.  Any ideas what's going on?
    Thanks a bunch,
    Anthony

  • MuVo2 low output po

    Hi!
    I have a MuVo2 ,5 GB player, and I have a problem. I read an review on the Internet about my player, and they wrote that the MuVo2 player has one of the greatest output power. The guy who tetsed it, wrote that when you have the full volume (with the same headphones that I have) it's very hight, and I mean very high volume. On my player, the full volume is not high at all, so with some headphones the volume is high enought.
    On Creatives homepage, you could read that the output power is 2 x 5 mW, and this is the same as it is on my brothers player (it's not a Creative), but his player can play much louder than my could, and the diffrence it's big.
    A friend of mine, has I Creative Zen Micro, and this player should have the same output power as the MuVo2 ,5 GB. But also here, it's a big diffrence.
    So, it had to be somthing wrong with my mp3-player. Anybody who has this problem?
    /Johnny R.

    The MuVo? series has an OK output as far as volume goes, but it is far from being the highest output of any mp3 player. If your volume though is decidedly low, then you could have European firmware which has a volume limitation. Under Settings | Information you can see your firmware revision. If it has an E on the end then it is the lower output firmware.
    Visit www.nomadworld.com | downloads section and download and install the latest Non European firmware for your MuVo?.5.
    If that is not the case, your headphones could be a high impedance which will lower the volume, or you could have a problem. Try the firmware check first though!

  • I-trigue 3400 soundwoofer not working / right speaker low output compare with left speaker

    Hi, basically i have 3 sets of creative i-trigue 3400 purchase as second hand. All these 3 sets have some minor problem. I trust my ability i able to repair it as iam a professional electronic engineer. Just need some advance information or guidance from creative big brother and sister.
    i do check with the controller everything, because i have 3 sets so i able to verified the problem.
    1)subwoofer not output----Is it problem with amplifier or any transistor damage? How do i start checking and verified it?
    2)right speaker low output compare with left speaker----I already analysis it and would like to know is it the transistor prolem? Please let me know so i can start with my repairing.
    From what i know, this model seem like going to discord soon, so is it possible send me a partial schematic on the 3400 so i can repair. Please let me know and reply me, i am waiting your answer. Thank you

    seem like nobody reply my email, can creative technical provide some guide. I already mention i will repair myself.:angry:

  • Unsupported output signal for Sony Bravia KLV-32T550A

    I have a mac mini 2007 running 10.6.3. I am trying to connect to a sony bravia KLV-32T550A either through VGA or DVI. Both keep coming up with error message (unsupported output signal, adjust your pc signal)
    I have updated setting on the TV as per some forums I have read so am sure its not the TV.
    Now the TV says the native resolution is 1366 x 768 but there is no exact match in display settings. Could this be the problems.
    I have read that i can download switchresx and this should fix the problem.
    Can anyone shed any light on this it would be much appreciated>
    Thanks

    Definitely the second computer can be a big help. If you set up Screen Sharing between the two so that the mini's screen is shared over to the MacBook, you will be able to see the mini's screen on the MacBook even though the display connected to the mini is dark. And from the MacBook you will even be able to control the mini, so you can go into Displays Preferences on the mini and make alternate selections for resolution and, if necessary, refresh rate. Hopefully you will hit on a combination that will light up the mini's attached display.

  • NI9401 output signal

    Hi,
    I am currently uisng the CDAQ 9178 and the NI 9401 modules to generate the output signal. Currently I am testing out using the 
    Generate Finite Digital Pulse Train Retriggerable.vi from the NI example finder. The main problem i am facing is the I can generate a pulse but is unable to vary the frequency on the go. Meaning to say, whatever value i set initially will be taken as the fixed value in generating the pulse frequency. May I know what are the ways to generate an digital output pulse signal that has varying frequencies? up to around 100kHz? 
    Hope someone could help me thanks a lot

  • Change form of output signal without initializing new process of output signal

    Hello!
    How to change form of output signal produced on the output channel without initializing new process of output signal?
    Thanks 
    Message Edited by _Pavel_ on 10-28-2009 05:21 PM
    Solved!
    Go to Solution.

    I'm working with LabView 8.5.1.
    I have periodic TTL impulse with constant frequency – signal to start , which I'm used to start data acquisition (PCI-6251)and generation signal (PCI-6221).
    When TTL signal a detection, necessary generation some analog signal (PCI-6221) and acquisition other analog signal (PCI-6251).  Then wait following TTL signal.
    At this moment I write the part of the program which is responsible for data acquisition. Function retriggering (In examples C:\ProgramFiles\National Instruments\LabVIEW8.5\examples\DAQmx\Synchronization\Multi-Function.llb\Multi-Function-CtrRetrigg Pulse Train Generation for AI Sample Clock.vi) is used. This function necessary,because we start data acquisition each time on arrival TTL impulse, andrepeated creation of the virtual channel of data acquisition with the newtrigger spend a lot of time.
    The problem consists in the following. Generation of the data from other card should occur on the same impulse TTL as for the data acquisition card and then generation zero value.
    How I can realize it? I planned to change the form of an impulse of generation when detected TTL an impulse, without reinitialize process.

  • Min Receive signal power level at the atur from atuc

    Hi can someone help me with the min receive signal power level at the atur from atuc on a adsl router

    Hi Srikanth, 
    Just to get some background info, what type of signals are being generated? What device are you using to measure these signals?  Are all of your impedances appropriately matched?  And finally would it be possible to attach the file used for waveform generation?  What I am mainly curious about is if you are trying to generate a single signal at 70MHz or if you are trying to generate at 70, 72, 68,and 66MHz at different power levels.

  • Gateway In problem (Wroung output signals)

    Hi,
    I build a FPGA circuit to test.
    The source come from a normal simulink block “Pulse Generator”.
    After the signal go through the block "Gateway In", the output signal of the ""Gateway In" is wrong.
    Is there some one can give me some advice ? Thank you.
     

    The problem is your sample period on the gateway in block. It's only taking in one sample every second but your pulse is going much faster. And your simulation only runs for 0.001 seconds. So you're basically seeing the output of 1 sample.

    Hi,
    Remember that when we are deploying a wireless setup we should always do a site survey to determine the amount of APs you need, power levels to use on each AP, where to locate each AP so that you can get the required mbps per client on each AP since as you know wireless is half duplex and also a shared medium.
    Also depending on how god the signal quality is too each client they will get a required data rate.
    There would not be a specific number since this will all depend on the amount of clients you need to support on the site and bandwidth per client.
    Here is the link for the FAQ of a site survey.

  • What is the effect of output signal with the same sampling frequency but different number of samples?

    Hi,
    I'm using PXI4461 for audio measurement and there is a question about analog output. I'm using the Basic Multitone vi for generating multitone signal. The sampling rate is 200k and my question is how to determine the number of samples. I used an audio analyzer to measure the distortion of the output signal with 200k and 1k points and there are no different except the update rate. What number of samples is suitable for 200k sampling rate?
    Thanks,
    Bill

    The Sampling Rate determines the maximum frequency that you can see (the rate/2 according to Nyquist).
    The number of samples divided by the rate determines how long you will sample. This sample time can only be determined by you. Do you need .1 seconds worth of data, or 1 second? But note that the MINIMUM frequency that you can detect is 1/(Sample Time) or the Sampling Rate/Number of Samples. So if your system has a minimum and maximum frequency specification use that as your guild.
