  How can I measure the output of a sensor pwm ultrasound using the module or 9403

  Khalil,

  When you say 'measure' the PWM signal, exactly what to tell you?

  You're looking to measure the frequency or cycle of the signal function? You count the edges of the PWM output increase? Looking to control the waveform?

  With reconfigurable FPGA hardware, it is up to the user to define the function of the physical i/o on the FPGA chip. By connecting the signals as Adam suggests your digital pulse will be brought to the cRIO. In your FPGA program, you define the function. You can set a base counter or transfer digital data from single point to welcome you cRIO for floating-point more complex treatment. Example FPGA programs are located in the http://www.ni.com/IPnet.

  Hope this helps, please post any additional questions.

• Toshiba 32TL838: flicker after fw upgraded in the menus, using HDMI input

  Hello

  yesterday I updated firmware of my 32TL838 to version 6.4.0Y.1 / 94.6.27.8 using the upgrade feature network.

  After the upgrade, I reset the TV to start again with the factory settings.

  During the quick installation after the reset, I noticed a very bad video quality. The entire image flickered, had a ghost effect and looked at interlaced. The menus were almost illegible.

  Once the installation is complete, the TV switched TV (cable DTV) normal mode and at least the TV picture looked quite normal. While the input CABLE is selected, I can also open menus as before, they are displayed correctly.

  But as soon as I switch to the HDMI input, the image becomes nuts once again, just like during the initial installation, including recoveries of TV menu. Sometimes it becomes stable for maybe 30 seconds, but then he is paralyzed again.

  A few words about my setup: TV uses only input HDMI 1 and the cable entry, nothing else is connected.
  Links to HDMI input to a receiver Onkyo TX - SR508 AV which is powered by a Fantec 3DS4600 media player and the Blu - Ray BDP - S373 player.

  Because I expect the question of what-to-your-HDMI-wiring, I traded the HDMI cables but as expected which has not helped at all.

  At least, I seem to be successful by bypassing the problem when you use the Fantec drive.

  Before I updated the firmware, I was able to use the drive with 1080 p/60 Hz and the player has been installed as a result.

  Now I switched to 1080 p / 50 Hz, and the video image seems OK again. (However, I made a short test and as I said, sometimes_
  the image is OK for a short period).

  Unfortunately my BluRay player has no menu to change the frequency, so I watch BluRay or online services, the player offers, is impossible.

  So, what can I do now? A downgrade of firmware (if possible) would be a quick temporary workaround I could accept. But medium-term I'm expecting Toshiba to restore functionality that they promoted and for which I paid.
  (Youtube stopped working with the old firmware and it seems that 1080 p/60 Hz no longer works with the latest firmware).

  Anyone know how to downgrade the firmware using a USB? I already downloaded the previuos version tl838_853886.bin but I do not have a nail how (and if) it can be installed.

  Thanks for your advice

  Hello

  As far as I know the isn t possible downgrade firmware.

  But you said that you noticed this problem by using an external device connected to the HDMI 1 port.
  As far as I know the Toshiba 32TL838 supports 4 HDMI ports.
  I recommend you to check all of the 4 HDMI ports as well as to check all device configuration options.

  Check for example the rate of active movement + option available.
  This option allows to improve the rate of cooling of a TV

• 6009 outputs digital and analog input synchronization

  Hello

  I work in a program NI 6009. I want to leds by car with outputs digital NI 6009. For example, leads first will be on until what 200 micro seconds then second led will be on up to 200 micro seconds, and then first of all led will be on up to 200 micro seconds. I'll take led with photodedector signals and connect analog output photodedector input NI 6009. I want to synchronize the outputs digital and analog input and separate the first and second led signals the analog input for NI 6009 channel. How can you do with NI 6009? Please ADV

  You can not do with the USB-6009 case. Its outputs digital are software with a maximum speed of slightly more than 100 samples per second. The outputs can produce 200 microsecond pulses and cannot be synchronized with the analog input.

  You need a device with outputs digital hardware timed or counters that can produce a pulse outputs.

  You can synchronize a bit digital output and analog input recording signal on an additional channel to HAVE. Will allow you to see the photodetector and LED the drive with the same schedule and such resolution as described by the sampling rate I. The maximum sampling frequency of AI on the USB-6009 case is 48 kHz that is shared by all channels. If you have two lights to led and photodetector two signals maximum sampling rate would be 48 kHz/4 = 6 kHz which is barely fast enough for your 200 US signals. For more than 4 channels, it won't be fast enough.

  I suggest a simple oscillator circuit building and use it to clock a flip flop. This will give you alternating signals to drive the LEDs. You can use a line to reset the flip flop to give you control without the need for high speed.

• 9174 triggered output pulses and analog input synchronization

  Hello

  I have a cDAQ 9174 with a 9215 analog and a 9401 module. I wonder if this configuration is suitable for my use: a trigger digital extern is sent to the system to trigger a task of analog input, trigger a generation of pulses, with another counter, count of trigger events. Using two counters on 9401, it seems I have no left Terminal at the entrance of my trigger signal. The trigger DAQmx vi does not show counters entries in the list of signals; and if I select a PFI line, an error that says that the line is already in use..., I missed a few obvious solution? I have change my 9401 to a 9402 did?

  Thanks for any help,

  Vincent

  Hi Vincent,.

  So, looks like you need a single line to use as input to trigger events and another line to use for a generation of pulse output.  This should indeed be possible, since the 9401 has 8 lines that are configurable nibble (i.e. lines 0:3 could be configured as inputs, while the 4:7 lines could be taken out, or vice versa).

  However, a big caveat with the 9401 is that the lines must be reserved before each task is started.  This is a limitation of the direction of the line is implemented in hardware and is common as customers when something they using the 9401.  Explicitly reserving your tasks before starting must correct the behavior if that is indeed what you see.

• using an input file

  For most of the scripts I created, I did:

  $vmlist = "blah", "blah1", "blah2" <-hold the file located in c:\tmp\inputfile

  
  foreach ($vm to $vmlist)
  {
  Get - VM $vm | Select-Object - Property Name, NumCpu | FT - AutoSize

  I really want to use an input file instead of list that I am above. I've tinkered with it but im just don't get it.

  Thank you!!!

  Hello, drivera01-

  You can use something like Get-Content or Import-Csv to take input from a file.  Since you are just a list of names, you could make an input file that has a name of virtual machine per line, use Get-Content and then iterate over the list of names of virtual machine, such as:

  ## get the list of VM names from a text file$vmList = Get-Content C:\temp\inputFile.txtforeach ($vmName in $vmList) {Get-VM $vmName | Select-Object -Property Name,NumCpu | FT -AutoSize}
  

  Or, in this case, since Get - VM accepts an array of one or more names of virtual machine, you can just pass the list "imported" to hold the names of virtual machine once you did call Get-Content, like:

  ...## no need to use a foreach loop in this instanceGet-VM $vmList | ft -AutoSize Name,NumCPU
  

  (also cleaned the part select/ft a little).  Other ways to use an input file will result in Import-Csv if you have a bit more involved data or Import-Clixml if your input data is in XML format.

  How do I?

  ESXi 4.1 is almost complete used hard drive... but... in fact, it is not true.

  Can someone show me dirrection to solve this problem.

  Hello

  Regardless of the type of disc you use once in VMware ESX allocates space on the disk it will never resume. It will happen as two snacks of thin disc as thick disk. Only difference is that the thin disk allocation is on request and for thick it is pre configured.

  Now, when we see inside the guest, he will see some quantity using comments he will never see beyond that, because of virtualization. But the esx host is aware of what his size allocated to this disc.

  Please see KB http://kb.vmware.com/kb/1022242 for more information on the types of disk in VMware.

• Help to find the flaw in a removal script of snapshot using an input file

  I would like to create a script that will make use of an input file which bears the names of virtual machine containing the shots with a common name. I used some of the logic in the script to create snapshots and I'm boning remove them now. I have attached the script to delete the input file and the creation script. The creation script works fine using the input file, but I know that my logic of the delete is wrong. Please let me know if you can see are the corrections is necessary

  You need to replace this line by the that I've shown in the code snippet.

• Measure the time difference between a digital output and an analog input that responded to the questionnaire

  Hallo,

  I use the following system:

  • OR PXI-1044 with controller NI PXI-8109
  
  
  • OR PXI-2564 switch module to turn on the monitor of my test device
  
  
  • Data acquisition multifunction NI PXI-6259 to measure the signal that responded to the questionnaire jump

  The two cards are the same - PXI trigger bus. For both, PXI-2564 and PXI-6259 I use DAQmx to set the reading and writing of the channels.

  Now, I want to measure the time between the digital output, my unit turns and the analog input, which measures the response of my system.

  I can't do work by myself, please help me!

  I thank Ludwig.

  Hi Ludwig,.

• Is it save to use the digital output as a digital input for another channel signal

  Hi all

  I know it's a stupid question, but I don't have another generator of signals by hand. What I want to know is, can I use the signal digital output of my USB-6001 as an input for the same signal device, but on other digital port? I wasn't directly because I don't want to burn the device...

  Thank you

  Done all the time. No problems.

• I have two sound cards. Can I use the input to the output to another?

  Basiclly the problem I have is that I use one of my as a configuration of 5.1 sound cards speakers (I put the MIC and line as output) and I found another sound card in another PC. The question that I have, that now I'm not a line or a microphone available for the first sound card, is possible to distribute the Line In input of the other card, to the first?

  Hi KiralyAlex,

  Unfortunately, it is not possible to perform this task, because at some point that a single sound card can be defined as a default device.

  However, you can use your favorite search engine & download any third-party software that could serve the purpose.

  Note: Using third-party software, including hardware drivers can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the use of third-party software can be solved. Software using third party is at your own risk.

  Hope the helps of information.

• Using text input/output of Captivate Exhange

  I have used Captivate for the basics, but I'm looking to do more. I downloaded the Text Input/Output of Captivate Exchange files, but I can't find any instructions on how to apply.

  My question is how to bring these to a piece of Captivate and use?
