• energy consumption of iMacs

  Why put you a power 310w supply when at full load can take up to 360W? and who knows how many with lots of memory and i7 upgrades.

  They need at least 400W.

  It's really bad and it reduces the overall performance.

  Of course, the loss is thermal too but who cares for that when pay us that much for a so-called high-end machine...

  I do not understand you Dear Apple...

  Also why not to provide information about energy consumption when is right to the wall outlet? Do you know that it is not zero?

  And he plays 0.7W 2W to an iMac but 14.2 and other models is almost the same...

  Besides on temperature problems...

  and I have 2 iMacs comes only from your amazing operating system.

  I'd rather have an answer of an Apple certified technician.

  Thank you.

• Energy consumption high (30W) on Tecra A4

  Hello!

  My A4 battery only lasts for about AN hour at full load! NotebookHardwareControl shows a 30W energy consumption. What's wrong?

  Círdan
  p.s. I recently bought this used laptop.

  Hello

  I'm sure you know that the battery consumption depends on parameters of use and portable computer power. I hope that you have set all to reduce the consumption of energy and in this way, the battery life should be a little longer.

  By the way: Tecra A4 is one and a half years and it is possible that the battery is not in the best conditions. When you buy a laptop used you don t know how the previous user has dealt with laptop and the battery.

• Energy consumption

  How much energy a computer consumes approximately per hour (LCD) when we Disconnect?

  Also if anyone can compare the energy between disconnection and sleep or stopping, it would be much appreciated. Thank you.

  As much wood as a woodchuck could chuck if a woodchuck could chuck wood.

  Who wants to say, not much.

  The "logout" 'sleep' and 'shutting down' terms are not very accurate, especially the last two.  A precise answer to your question depends on the number and type of components which continue to receive and use the power in each of the different States.

  For example, if you "log off", basically everything is still working but there is no charge special calculation on the CPU.  On the other hand, if you "shut down" but let all plugged into a power source, there are still energy consumption (see below).

  You might be interested in the following site, which offers a sort of rough estimation of energy consumption for different configurations of workstations House--> http://www.apc.com/tools/ups_selector/index.cfm

  If you really want to know what your computer uses in terms of power, you have to take measurements in different configurations by using a tool like this--> http://www.newegg.com/Product/Product.aspx?Item=N82E16882715001

  Interesting part of the review of a user of the device above:

  My home theater system complete (receiver, amplifier, BR/DVD player, TV, Wii, cable receiver DVR, some other misc stuff) uses ~ 130W when everything is turned off.

• Photosmart Premium Fax C410 - energy consumption

  I see the average energy consumption of the product, but I don't see any reference to know if there is a 'standby mode '.

  (1) is there such a fashion?  If so, how much energy it consumes?

  (2) the product must be left on when it will not be used for several hours?

  Hello Acover,

  To answer your questions.

  (1) is there such a fashion?  Yes, it has a standby mode. If so, how much energy it consumes? Power consumption: 34 active watts, 4.4 watts sleep, 6 watts, 0.4 watts manual stop reserve

  (2) the product must be left on when it will not be used for several hours? As the device has a fax machine, and I'm guessing that you do not want to receive faxes, you must leave it on. If you turn the unit off faxes will be received. It is also the reason why a standby mode is in the unit.

• How to calculate the execution time of a SCTL in FPGA VI?

  Hello

  Can someone guide me that how to calculate the execution time of a SCTL for an iteration in the FPGA VI?

  Thank you and best regards,

  Rashid

  Hello r,.

  A SCTL will always run in a beat the clock it has been linked to.  So, if you use a 40 MHz clock, this loop will run in 25 ns.  If the code cannot complete in that, or if it requires two graduations of the watch to do the calculation, your code does not compile, then you have the guarantee that this will always be how long it takes this piece of code to run.

• To build the waveform.vi function how to calculate the value of dt

  Dear all

  Please guide me How to calculate the value of dt according to waveform.vi of construction

  My sampling rate is 25000 and I take 200000 samples.

  Kind regards

  Muhammad Irfan

  It's all simple arithmetic. The inverse of the sampling frequency power of samples is then the dt or the time between samples the number of samples is not relevant.

• Series Packet Question: How to calculate CRC

  Hi all, I have tryied to find an answer on how to calculate the CRC on a RS232 packet received, its really driving me crazy!

  im a beginner, learned how to use labview read on different forums, and I had managed to build really good applications, but im stuck in this, hope someone can help me...

  OK, so im constantly receive packets of 15 bytes:

  A5 09 0C 00 61 05 1F A0 10 00 05 00 04 05 3F

  A5 09 0C 00 61 05 10 00 05 0C 2F 03 A0 1F-3F

  A5 09 0C 00 61 05 10 09 05 09 04 09 A0 1F-3F

  the supplier for material gave me the following code to calculate the CRC:

  Control CRC program:

  #define unsigned char uchar
  UCHAR CRC_Bitwise8 (uchar * buf, uchar size)
  {
  UCHAR i, j, b;
  UCHAR crc = 0;
  for (j = 0; j<>
  {
  b = * buf ++;
  for (i = 0; i<>
  {
  If (((CRC^b) & 0x01)! = 0)
  CRC ^ = 0x18;
  CRC > = 1;
  b >> = 1 ;
  }
  }
  return crc;
  }

  so my question is, how can we insert this code in labview? any example?

  Thanks in advance, this forum has really helped me learn labview in a practical way.

  You can use my code for the thread that I've referenced.  To play with a web version of my code go here. My code is based on the code on this Web site.

  My code to the following parameters:

  Calculation of the CRC: Other (specify)

  Order of the CRC: 8

  Polynomial CRC: 0 x 30

  CRC initial value: 0

  CRC XOR final value: 0

  Reflect the preprocessing of data: TRUE

  Match the data before Final XOR: TRUE

  In your messages, the A5 09 0c is certainly a header.  I think that the 00 following is also part of the header, but without the manual, I can't confirm.  00 will not affect the calculation of the CRC, in order to get the same results with it and without it.  So, in your first example, I use 61 05 3F 1E A0 00 05 00 04 10 and the result is 0x05.

• the time of acquisition of data - how to calculate the rate of analog output

  I want to calculate an acceptable rate of analog output, one that is taken in charge by material (PCIe6353), without the rate being changed by the VI DAQmx Timing (sample clock). The final objective is to have a rate of analog output that is an integer multiple of the analog input for precise frequency, since the sinusoid AO's amplifiers, which have a ringtone when AO updates occur.

  According to 27R8Q3YF of the knowledge base: how the actual scanning speed is determined when I specify the rate of scanning to My d..., the rate is revised as needed by calculating the rate of clock / asked for advice, divide the result rounded downwards and upwards in the clock of the Board and use the one that is closest to the requested speed.

  If 'Embedded clock' is selected, which is the result "Council clock.  DAQmx sample clock timebase Timing node - SampClk.Timebase.Rate says 100 ms/s. However, for a rate resulting from the update of 2.38095MS / s, the divisor of the time base timing node - "SampClk.TimebaseDiv" gives a value of 42. 42 x 2.38095 M = 99, 999, 990, where it should be 100 ms/s.

  How to calculate an acceptable rate of analog output is supported by the hardware? I have other plates, in addition, a general method would be appreciated.

  I haven't worked all the details yet but noticed a few things that may be relevant.

  Req AI rate isn't a whole ditch 1E8. It is used to determine the rate of the AO.

  There is no check to ensure that the rate of the AO is an integer division.

  It seems that you have the right idea, but the implementation is not yet there.

• How to calculate the polynomial graphic adjustment of waveform

  Hi all

  I am new to lab - view so would need a little assistance in one of the problem I have right now.

  My problem is: how to calculate the polynomial graph of waveform data adjustment? I need to convert the waveform to XY graph data, and then use the polynomial vi made integrated to calculate the fitting?

  Detail: My problem is that I have waveform graph, I calculate the vertices and the Valley, but because of the noise, my peaks and Valley detection is sometimes not exact, so to smooth the chart that I must apply the polynomial fit.

  If anyone can help me in this, I'll be very grateful.

  Thanks in advance

  Hi Omar,.

  have you seen the suggestion of Lynn above?

  You already have the values of Y (your table). Now, you need build the table of X as indicated, only to replace the value of dt with your spacing from point to point. Somewhere in your code, you know that the value that you have an x-axis indicated in milliseconds...

• HP LaserJet Pro 200 M276nw working condition and energy consumption.

  So that the energy state of the printer and its energy consumption, I wanted confirmation of the information:
  1) operation (print, scan,...)-on the energy consumption of 310 to 315 watts
  2) sleep (the printer is ready to accept any work, even wifi, before any print offers email ePrint) - power consumption about 13 watts
  3) idle (done printer does NOT work on wifi, NOT to print the ePrint e-mail offers, wake up within the parameters of the function of AUTO ON-OFF AUTO)-about consumption 6.5 watts
  4) off to switch manually (no operation) - on the energy consumption of 0.2 Watt
  All of this is correct?
  Thank you

  Hi fabris66,

  If I understand correctly you want to know if the printer must be in mode standby in order to receive an email using eprint.

  Yes, the printer must be in standby mode or on and connected to your home network.

  Hope that helps.
