  Hi Aron,

• How is the SHA hash for a generated module?

  Hello

  I was wondering if someone had more information about the CodeModuleManager.getModuleHash () method?  The API says:

  "Returns the algorithm SHA hash in a module."

  I've used it before and it gives me what looks like a SHA1 hash.  The only problem is, I'm not able to reproduce this hash by generating a SHA or SHA1 hash using my computer.

  For example:

  If the BlackBerry gives me 02A826682116ED6A7B9B4429CAAFD2DF198A29F7 for the net_rim_app_manager module, running the same .cod file does not provide me with a corresponding number:

  azazel:tmp sheran$ openssl sha net_rim_app_manager.cod SHA(net_rim_app_manager.cod)= 03804aa899166d0eed95ddf3a758446c2159ee4b
  
  azazel:tmp sheran$ openssl sha1 net_rim_app_manager.cod SHA1(net_rim_app_manager.cod)= 7feebefdad9a39d98c70d0282cca935fd2dc55fe
  

  My questions:

  1. How did this hash generated for a specific module?

  2. how the calculation would be different for a module with many brothers and sisters?

  Thank you

  Sheran

  The tail of each signed module is a list of signatures. When you calculate the SHA-1 hash, you must exclude this part of the binary file to hash.

  When a module is composed of several modules, it is in fact a ZIP file. Each ZIP entry that contains a module (brother) has its own hash and signatures. Easiest way to test this is to decompress the. COD file and calculate the values of the hash for each file.

• With the help of the external RF signal generator

  Hello.

  I just want to ask how can I remove the frequency shift if I use an external RF signal generator (instead of the RF PXI-5652 signal generator module). I understand that in the case using the OR to generate RF signals, frequency shift is deleted by setting the same source of reference for the transmitter and the receiver clock (placing the clock source of reference to PXI_CLK of the façade of generation VI and VI of the acquisition).

  Thank you very much.

  Hi Betty,.

  In this case, no changes are needed, such as modules OR still use background clock basket PXI as the ref. clock source If you are still having a frequency shift, you probably need to configure sig gen to lock a clock external REF. Usually, just make the connection of the signal is not enough - you must also indicate the sig gen to use the signal connected to the input clock ref. Terminal

  If you use the sig gen as clock source master Réf, connecting the 10 MHz of the gen of GIS at the BNC 10 MHz IN on the back of the PXI chassis replaces the clock native from the newly connected with the PXI chassis backplane, and analyzers are still using the clock background basket PXI as the source clock Ref (no change to the SW settings).

• Coded frequencies-16 generator control switch

  I feel really lame to ask this, but I can't understand how to connect a code switch to select 16 different frequencies in the generator module. I keep trying to figure out how with a switch output and a generator of output that I can control the generator of the switch. I can't imagine how the goes - inta and outta goes to get wired.

  I keep thinking, I saw one such example, but can't find it

  CJ, the example was everything I needed to make things work properly. It was logical that the output voltage of the coded switch would control the signal generator which he does very well.

  Thank you very much!!!

• TestStand - dynamically retrieve a prototype of code module

  Hi all

  Thank you for reading me

  I am currently trying to find little code (if it exists), or some ideas/directions to automatically retrieve a prototype of code module.

  This code can be written in any language (LabVIEW, C, TestStand, or other)

  My final goal is to scan a directory for screws, dll (and so on) and get their prototype in order to have an external database generator module filled code.

  Where there is no such thing as this code, could you please let me know what methods I could interact with the TS engine to retrieve a code module.

  Best regards.

• Demodulation

  Hi all

  I'm doing EVM measurement signal (modulated using 16QAM) OFDM using VST SMU-5645R.

  But I get 0 and one EVM constellation evil.

  I am not able to solve the problem. Can someone help me please? I have attached the image of the part of demodulation of the code with this message.

  Thank you

  Anupama

  Thanks, Anupama. The new link works.

  Your EVM measurement occurs only on the data passed out of your loop to demod. I noticed that you have no output condition on this loop, with the exception of a mistake. In this case, the data passes out will be empty (the only mistake might be a time-out of the dequeue item or symbols calling card MT). I don't know how the loop could out at all because there was no time limit set on the primitive dequeue item.

  Second, remember your last post you must set samples by the symbol of an even number.

  "With the samples per symbol being two, beginning for the input stream being relaxing ' Output Stream Start Trigger", and the reading block size 16000, I was able to get the data. Oh, I plugged in also the loop demod to leave first data table size is greater than 0; otherwise, the extent of EVM is never executed. Do you want the EVM measurement in your loop demod? Note that the data was not very good. I don't know exactly why, but would it be a problem with your calculations demod? Is there a reason that you do not use the MT demod VI?

  With all that said, what you're trying to do with this project? If you try to measure EVM to a QAM signal, have you tried running the "MT RFSG generate QAM' and"MT niRFSA QAM Demod"example screws at the same time? You try to make a few additional calculations?

• DASYLab how to write data to a file every 15 minutes

  Hi all

  I use dasylab and datashuttle/3000 to record data. What I want to do is to write data to a file every 15 minutes. I use the milti-file, which can write data to the file diffenret, but how do I control the timing, as the journal data every 15 minutes automatically.

  The other problem is that I use FFT analysis of the frequency spectrum. How can I determine the value of frequency where the peaks that happens.

  Thank you

  Write less data in the file that you have collected requires the reduction of certain data.

  There are three techniques to consider.

  With an average or an average of block - both reduce the data by using a function of averaging, defined in the module. To accomplish the reduction of data, choose block or RHM mode in the dialog box properties, and then enter the number of samples/data values that you want to reach on average.

  Average - when you reduce the data, you also should reblock data using the block length of the change in the output parameter. For example if you enjoy at 100 samples/second with a block size of 64, the average module configured on average, more than 10 samples will take 10 times longer to fill a block. The initial block represent 0.64 seconds, the output block represent 6.4 seconds at a sampling rate of 10 samples/second. If you change the size of output in one block, the program remains sensitive.

  Average block - average values in a block against each subsequent block, where the average is based position. The first samples are averaged, all second samples are average... etc. The output is a block of data, where each position has been averaged over the previous blocks. This is how you will be an average data FFT or histogram, for example, because the x-axis has been transformed in Hz or bins.

  Second technique - separate module. This allows to reduce the data and the effective sampling rate jumping blocks or samples. For example, to reduce the data in 1000 samples / second to 100 samples per second, configure the module to keep a sample, jumping 9, keep one, jumping 9, etc. If you configure to skip blocks, you will not reduce the sampling frequency, but will reduce the overall amount of data in a single block 9, for example. It is appropriate for the FFT data or histogram, for example, to have the context of the correct data.

  Finally, you can use a relay and a synchronization module module to control. For example, to reduce a sample data every 15 seconds, configure a generator module of TTL pulses for a cycle of 15 seconds of time. Connect it to a Combi trigger module and configure it to trigger on rising and stop the outbreak directly, with a trigger value after 1. The trigger output connects to the X of the relay command input.

  In addition to these techniques, you can change the third technique to allow a variable duration using a combination of other modules.

  Many of these techniques are covered in the help-tutorial-Quickstart, as the data reduction is one of the most frequently asked questions.

  In regards to the FFT... use the module of statistical values in order to obtain the Maximum and the Max Position. The Position of Max will be the value of the frequency associated with the Maximum value. The output of the statistics module is a single sample per block. Look at the different FFT sample installed in the worksheet calculation/examples folder.

• niRFSG Initialize.vi error: AWG resource name is not valid

  Hello

  I use an SMU-5442 arbitrary signal generator and a PXI RF Upconverter - 5610. The RF PXI-5610 converter is PXI1Slot5 inside the MAX and the SMU-5442 AWG is PXI1Slot7.

  When I gohttp://ftp.ni.com/pub/devzone/epd/rfsg-generate-fm.vi of http://zone.ni.com/devzone/cda/epd/p/id/5620 , I get the error messages.

  For the resource name = PXI1Slot5

  code-1074117675
  
  niRFSG Initialize.vi a session cannot be created because the resource AWG name is not valid. Specifty the resource name of AWG Max by right clicking on the converter, and then select Properties. If you specify the working group through the chain of the Option, make sure that the resource name of AWG is valid.

  For the resource name = PXI1Slot7

  code-1074117636
  
  niRFSG Initialize.vi the specified device is not supported by this driver.

  which is correct, because PXI1Slot7 is the GTA and the VI is just using the niRFSG screws

  When I use a selector instead of the string of the Option, I can only choose the RF PXI - 5610 Upconverter is PXI1Slot5, but I still get the same error message.

  A you link them in MAX? In other words, the converter and the working group.

• output signals of the rectangle a PEAK sine wave conversion

  Hello

  I have a question on the treatment of a PIC16F84 output signals. It seems that the simulation of Multisim does not work properly - but before I blame Multisim, I ask the community NOR or software engineers or a solution. Because I'm German, you are invited to continue this thread in German if it is allowed by the rules of the forum. If you need additional information to analyze my problem, I'll be happy to provide.

  The circuit itself has to convert "composition by pulse" signals "tone" (DTMF tones). So you can get old, classic phones work on new devices that do not support the "composition of pulse" more.

  The circuit is powered by the analog telephone line current loop line. The PIC is provided by a rudimentary voltage regulation and count pulse signals (voltage failures / power interruption on the telephone line). After that the captain means the series of impulses in their equal number (e.g. 3 pulses = number 3). The captain gives finally two signals with different frequencies to generate a DTMF tone (e.g. number 3 here is 697 and 1477Hz). As you can see in my PDF file attached, it works very well.

  Now I have to convert the rectangle wave given by the captain to an at least similar to a sine wave form - otherwise the device that receives the DTMF tones won't understand them.

  So I connected a low-pass filter at the output of the PIC. Now, expect the rectangle signal to be smooth in a way as the 'e-function' will (loading / discharging a capacitor through a resistor). But the results are very far from that - as you can see I have very strange curves.

  When I implemented a frequency generator with the same output signal as the PEAK and the low pass filter even I get curves as expected.

  So we can say that the output of the PIC works like a frequency generator in my circuit. But why does the filter not behave as it should?

  I've tried a lot of different values for the parameters of my RC-filter and simulation - this does not solve the problem.

  It would be nice if someone has any idea how to solve this problem.

  Thank you.

  The output impedance of the PEAK may be too high. May be that my car 50 output? Try scaling of impedance of the filter.  Do the 10000 ohms resistance and capacitor 10 nF.

• Save all the data for a while loop

  I already asked a similar question, but it is perhaps not very clear, and there are a few concepts that I did not understand.

  1. I have a keyboard to generate flow DTMF signal (I call it stream because it contains several shades that consist of a full phone number)

  2. I would like to save it as a wav file, but I guess that another format is correct and because the writing on a wav file does not support add so for this particular case, I use writing waving instead of writing to wav format

  My approach is to have a structure of queue so that I can write each iteration results in a file.

  (i) when I try to retrieve the data, there's nothing but 0.

  (II) my intention is to get 8000 samples per second (fs = 8 000) but he back up data so fast

  I have attached the file so if there is a way to solve problems, please help me.

  This vi includes many elements discussed above. There are no provisions for the intervals 'no signal '.

  Changes: Replaced with native features of LabVIEW Mathscript node. Mechanical Action to latch release button.  Cluster to array replaces Unbundle and table to build. Reshape the table to match the shape of the keyboard. Separate searches for frequencies of line and column. Note that this is easily extensible to handle the 4 x 4 keyboard. Structure of the event added. Added the stop command (but not implemented stop to the loop of the file). Added indicators for diagnostic purposes. Added FFT spectrum and graphic.

  I disabled writing to part of the file for testing.

• Impossible to compile the FPGA in project

  Hello I get the following error when I am trying to compile an FPGA VI on a Compact Rio 9022, I missing something on my stand in? Everyone has seen this before and know what is happening? An internal software error occurred. Please contact National Instruments technical support on ni.com/support with the following information: 7 error error component the generator module VI: NULL Possible reasons: LabVIEW: File not found. The file may have been moved or deleted, or the path to the file would be incorrectly formatted for the operating system. For example, use- as Windows path separators: on Mac OS, and Linux. Check that the path is correct using the command prompt or file Explorer. ========================= NOR-488: The non-existent GPIB interface.

  This looks really familiar.  I know I've seen this error.  I think there is a problem if you upgrade to the latest NOR-RIO, but you don't put at level LV FPGA 8.6.0 to 8.6.1, or something like that.  Would it be, kmoyna?

• Name of the PKI trustpoint client?

  I have two routers directly connected to g0/0 R2 R1 g0/0 lab.

  I have IPsec with preshared keys configured and everything works fine.

  I just finished setting up R1 as the CA PKI server and created a better priority isakmp policy to use when certificates are configured finally between R1 and R2.

  My next task is to configure R1 also as client PKI.

  I ran crypto key generate module general key of rsa 512 - everything is good, no problems yet.

  Now I need to create a trustpoint to the CA server and this is my question-

  Can what name be used - which means that what I have to use the same name that the server CA [R1-CA] or any other name of the ol is well?

  My config for R1 below.

  Thank you again once - I will get it working soon - I hope!
