Maximum frequency for digital counter input

• Sampling frequency for digital sampling (cDAQ-9172 & NI 9401)

  Hello!

  I have a cDAQ-9172 with NI 9401 C-series (digital) module. I would like to taste the digital inputs with a sampling frequency of e.g. 400 or 200 kHz. My problem is that I can only choose a clock 100kHzTimebase and therefore only get a sampling rate of 100 kHz. The 20MHzTimebase clock is too fast, as it gives me a sampling rate of 20 MHz). Is it possible to get a defined user e.g. 200 kHz sampling frequency, dividing for example down the clock of 20MHzTimebase?

  Thank you! Last post and this article using the internal one or cDAQ chassis counters has solved my problem.

• Function DAQmxRegisterEveryNSamplesEvent can be used for the counter input channels

  Hi all

  I have a request to count the number of digital pulses. I want to know the time of impulses coming which start from 1 and an increase in later, 4 as 1, 5, 9, 13... The time interval between each pulse is not a fixed value. So I tried to use DAQmxRegisterEveryNSamplesEvent and DAQmxCreateCICountEdgesChan functions. But afterI calls the DAQmxStartTask function, it has always failed.  The advice that I used is the NOR-PCIe-6320. Here's the part of my code.

  DAQmxErrChk (DAQmxCreateTask("",&m_taskhandle));
  DAQmxErrChk (DAQmxCreateCICountEdgesChan (m_taskhandle, "Dev1/ctr0", "", DAQmx_Val_Rising, 0, DAQmx_Val_CountUp "));
  DAQmxErrChk (DAQmxRegisterEveryNSamplesEvent (m_taskhandle, DAQmx_Val_Acquired_Into_Buffer, 4, 0, EveryNSamplesCallback, this));
  DAQmxErrChk (DAQmxStartTask (m_taskhandle));

  I don't know the reason. Can someone give me help. Thank you.

  DAQmxRegisterEveryNSamplesEvent only works with the buffered in memory tasks.  That's what you should do anyway (if you want to use the callback or not):

  1. make your external signal the sample clock (DAQmxCfgSampClkTiming).

  2. use one of the basics of internal time as the source (DAQmxSetCICountEdgesTerm).

  Each sample you read will give the count in ticks of the time base.  Multiply the number by the base of your time period and you now have a timestamp.  Keep in mind the counter roll to 2 ^ 32 therefore account for this in your program.

  The recall is not necessary, but it is useful that you can make sure that you block your main thread until the samples are available.

• Maximum speed of digital output of the DAQ 6009

  Hi all

  I'm trying to generate a clock the digital output on my USB DAQ 6009 puse. The maximum frequency, that I was able to produce was 0.5 kHz, but I would like to generate at least 1 kHz. I HT wired port0/$line0 of the OID of data acquisition to the data acquisition ai0 and attempted to read the output via the input of an analog of the same device. I have attached the programs here. Don't know if it's right. You can help. Thanks in advance.

  150 s/s is the maximum rate of the analog output.  The 48kS/s is the maximum rate of the analog input.  Read a little more closely.

  This unit will not do what you want.  I recommend putting the hand of your representative local of NOR and discuss your needs with them.  They should be able to set you up.

• Maximum frequency of RAM to Satellite C650-1CC

  Hello

  I want to buy RAMs again, but I know Don t, how is the maximum frequency, which can use my cell phone. If he isn´t no need to buy a RAM with frequency with 1600 MHz for example.
  Now there's the Rams with 1066 MHz frequency.

  Thanks for the reply

  Satellite C650-1CC (PSC08E-03H006CZ)

  According to specification for laptop, your laptop can be upgraded up to 4 GB. For the moment, there must be 3 GB inside and one of the modules is 2 GB. Only thing you can do is to get the same second RAM and use 2 x 2 GB. It must be DDR3 1066 MHz (PC3-8500).

  You must use the identical two Rams and you will have only a few compatibility problems.

• Serious problem with CPU 'maximum frequency.

  Hello

  I have a problem with my W510.

  I think that this problem has been around since I bought it, or at least for a month or two after I bought it.

  When I plug the power in, or out, it almost always affects maximum frequency of the processor, as seen in the Windows 7 resource monitor, as well as a program called CPU - Z which shows in fact the current speed of the base.

  When things work correctly, the basic speed is slightly more than 3,000 Mhz.

  However, this speed changes whenever I plug the power inside or outside.

  Usually, it changes for the worse when I plug IN power!

  Often, to plug in, the speed drops to about 1 000 Mhz. Then I Plug - and the speed goes back to 3 000 Mhz. Rebranchez_ the - 2 500 Mhz. out Plug - rest on 2 500 Mhz. Plug in French - 1 500 Mhz. out Plug - 2 500 Mhz. Plug in French - 3 000 Mhz. get out - 3,000 Mhz, etc.. Every once in a while, it even drops to 300 Mhz.

  It seems to be arbitrary and random. Sometimes, it takes me 10, 15 and even 20 times connect the power out and back in to run to 3,000 Mhz.

  The machine is new, there is no fan noise, and anyway, the changes are directly correlated to plug and power in and out and that they never occur themselves - is certainly not overheating or something like that.

  Also, I don't think it's a problem with the power itself, as happens to me in different countries and different places, and in any place if I try to re - plug power enough times - it will eventually be resolved (so of course that there is enough power).

  Is there someone who knows this problem? Any suggestions?

  Thank you

  I found that Throttlestop help me with my own problem speedstep. Speed moves much to light use because of speedstep, but when I use a cpu benchmark to load four hearts they set to max speed and do not move. You can give it a try.

• Sampling frequency for two different routes for acquisition of data USB-6009

  Hello

  I use a box USB-6009 and incorporating the "daq assistant" to change the sampling frequency.  I'm trying to find a way to set the sampling frequency to two unique values for the two separate channels.  I tried implementing two assistants daq and different for each channel sampling frequency setting, although it does not work.  Is it possible to set the sampling frequency for all channels, and then reduce the rate for another channel - or an alternative?  I would be recognizing any input on this matter, thank you!

  -Anthony

  All tasks on a DAQ card using the sample clock should use the same clock.  Therefore, you cannot have two tasks on the same sample of DAQ card at different rates.

  Alternatives would be:

  1. to combine all channels in a single task and to accept additional data

  2 get an additional DAQ card to use at the same time

• CPU Maximum frequency never exceeds 31%, even under load.

  Windows 7 x 64 runing. Brand new X 220, less than 24 hours old. All windows updates have been applied, etc.

  Power settings Windows resource monitor reports that the maximum frequency of the processor is 31%, regardless. I plugged on current alternative and have set the profile for maximum performance. I am running Prime95 on all four cores. No effect.

  CPU - ID confirms it, the speed of the CPU to ~ 790 Mhz whatever the load on the CPU of the declaration.

  I searched google and the forums and found a thread on the R/L series forum where people have had the cpu, the opposite problem was always running at max frequency: here it seems that their cause was raised by staff. It worries me...

  Looks like speedstep does not work in win7x64

  Is it just a display issue or is the CPU without limitation correctly?

  Thanks for any help.

  SOLVED

  The adapter using my old thinkpad 90W CA solves the problem. The simultaneous use of the dough and the 60W also solves.

  Apparently, my initial forum search wasn't very good, I found a close a few pages on the forums theme that connects to a long debate which essentially suggested these two things.

  Thanks, sorry for the pointless post.

• Paragraph styles are an alphabetical/digital count of a separate paragraph style.

  I need help to figure out how I can configure several paragraph styles, so you can start a digital count - have an alphabetical numbering inside the digital count - and then continue with the first, digital original County.

  I know that I based the alphabetical style off the digital-, but I advanced and based on any model b/c I thought that it was playing with her...

  Please help me if you can, I appreaciate it!

  When you set up the numbering of the paragraph style properties dialog box, there is a parameter 'list '. Used to create a new list for each p.style that must have its own numbering system, so that they different styles do not interfere.

• Hi, my places.sqlite file size is 30 720 KB I reached the maximum size, is there a maximum size for this. Visited links are is more changing color.

  Hello
  My places.sqlite file size is 30 720 KB I reached the maximum size, is there a maximum size for this.
  Suddenly the visited links don't change is no longer the font color, that I prepare for an exam, I need visited issues to change color, to follow up on issues that I ended. But if I delete a few days of history, then again once, most visited links change color and then it stops, it seems that something is getting full and not able to accommodate more? Why my visited links don't change color after a number of visits? I would like to make a back up of the file places.sqlite. So I tried everything to remove the profile, uninstalling reinstalling, creating a new profile, and then copy paste places.sqlite etc, but as mentioned after a few visits, visited links is no longer change color, if I delete a few days in history and then a few visits is again change color and then stop again, so what should I increase so that my quota of visited links is increased , I also tried tweaking about: config and there has been no result. Although I was not really convinced that _pages growing brower.history_max (don't remember the name, but I'm sure you get the idea) will help.
  Seems that while my visited links change color, quota is met and only if I delete the history of a few days will I get some links most visited to change color. Can someone enlighten us? As mentioned that my places.sqlite file size is 30 720 KB so I think maybe this has something to do with it? Would be very grateful if someone could help me. Thank you.

  Sorry it is not looking good.

  1. Unlike bookmarks history is not saved in Firefox.
  2. There is a possibility using Windows.
  3. Sync is not expected to back up things until the synchronization server
  4. If places.sqlite does not sort itself you may have to re-create remove it. You will lose your history, but can still access indirectly IF you have saved a copy of the appropriate
  5. Different databases to try to create new profiles
  1. History
     is rather less robust than bookmarks, you should deliberately somehow return it upward, but it's too late now
  2. Earlier versions of Windows
     This is really the last chance. Make sure you have some places.sqlite you saved. Always before and after any attempt to restore the backup. Windows must be able to provide a previous version. One of these versions may be usable as is; or can be used after a repair with housekeeping. Of course, this is not the latest version but it should help.
  3. Sync is not a server backup service.
     Sync is intended to save on another device, no backup is the fact that the second device then contains synchronized information. IIRC Sync development ceased, and the replacement when available may include a server backup option.
  4. Recreate the database of bookmarks (including history)
     Unfortunately, recess can only use saved bookmarks, there is no saved history to use. Once the database is re-created, it will continue to store the history but it loses the existing history. This time take steps to save on a regular basis.
     • The backup profile or at least the places.sqlite in this
       Backup and restore Firefox profiles information

     • http://KB.mozillazine.org/Bookmarks_history_and_toolbar_buttons_not_working_-_Firefox#Rebuild_Places_database
  5. Use the new profiles for database testing.
  
  To simplify comparison of the results of the database different files create one or more new additional profiles. Then try to smash the places.sqlite file into the test profile with any other places.sqlite, you want to try. Allows you to directly compare the databases, without seeking to use sync and without changing the Firefox profile work unnecessarily. You can keep a reference profile of studies with the best of the profiles of any shows results of history; According to the best recreated or corrupted database is.
  • Use the Profile Manager to create and delete profiles Firefox
  • CARE, do not rename or delete profiles created once or use anything other than empty folders when they are created. Don't nest in the other profiles. (At least until you know exactly how it behaves - post back if you never consider such actions)

  Hello

  I think this old laptop HARD drive with IDE interface, so I think the upgrade up to 120 GB should be possible. I think that 80 or 100 GB should be enough for this good old classic.

  I hope you aren't the guy who wants to have 500 GB. :)

• Memory maximum capacity for Ideacenter B300

  I have an Ideacenter B300 all-in-one, bought in India. I see that there is only one slot, with a memory of 2 GB. I would like to know if I can improve it with a 4 GB memory (memory only)? Or is 2 GB maximum memory for this device?

  Thank you

  Hello

  Hardware configuration of your system should support top of 4 GB.

  Question...

  If you remove the current RAM on your system, do not your system have two slots for RAM, by superimposing each other

  But technically, your system may work up to 4 GB Maximum.

• HP DV7-3063cl laptop PC: what is the maximum temperature for safe operation of the DV7 3063 cl with the upgrade of the 640 M CPU?

  I have recently restored a HP DV7 3063 cl laptop that died a hot mother (MB). I replaced the MB with a new Board of Directors of HP when the price has been reduced to $100, updated the CPU with an announced as new AMD 640 M and applied Arctic Silver on CPU and graphics chips. I put in 4 G memory cool, got the computer to work and installed Windows 10.

  The computer seems to run very hot and stopped twice from overheating during its first period of 2 weeks when it there was not a lot of calculating, fan was run at top speed at all times, and the laptop was high to allow good airflow below.

  According to the program of the Open Hardware Monitor, the CPU had reached 97-99 C a few times. I bought support cooling a player and that seems to help a lot, dropping the temperature to 20 ° C.

  What is the maximum temperature for safe operation of the DV7 with the upgrade of the 640 M CPU?

  Anything more than 90 c is too hot. You can specify the processor and the motherboard you have installed?

  Also if this from the Manual:

  Thermal paste is used on 1 CPU and heat sink section 2 that the services it. Thermal pads are used on the chip Northbridge 3 and 4, the graphical subsystem chip 5 contact Northbridge and graphics/heatsink contact 6. Thermal material replacement is included with all kits of spare parts of processor, heatsink and system board.

  So unless you have changed the cooling system to heat composed on the chip graphic you should have used a thermal buffer. Without the pad, it may leave just a small hallway and destroy the cooling properties. You can use a shim in copper or other piece of something metal to fill the void, but if you just put the heat sink down on the video chip you won't get optimal even with thermal cooling paste.

• measurement of frequency for ELVIS

  I use Elvis and I want to measure the frequency of an analog input signal.
  I use this program I found in a manual form OR.

  I'm using LABVIEW 8.0.

  The problem is that the program is not read the frequency. No mather how often I try to read always indicates r = the same thing.

  I have attacheted the program below.

  Americanu22,

  A couple of things that you will want to consider:

  1. to ensure the frequency information is correct, you must be 2 sampling * [highest frequency in your Signal].

  2. you can consider an ongoing acquisition with a configuration like this (' this example can be found in Help "" example Finder under material input and output "analog measures DAQmx'):

  Good luck!
