• 5142 reduce digitzation

  Hello

  I have a scanner 5142 with a resolution of 14 (16) bit. can I change this rate of 8-bit scanning, or can I get a signal to 8 bits using 5142. If so should it aso means I increased the speed of 200MBS 100MBS (since I'm only using 8-bit scanning).

  Concerning

  MADD

  Regarding your first question: when you switch to the mode low resolution (8-bit), you do not set the sampling rate, but it can be used to improve the flow to the host computer.  For example, when the digitizer is 14 bits (and sampling at 100 MSamples/s) mode, the device is to store 16 bits (2 bytes) samples in memory of the device.  Let's say you can extract the data from the device to the host (on the PCI bus) 100 MB/s.  This means that you can extract 50 MSamples/s memory of the device to the host memory.  If you switch to 8-bit mode, the sampling frequency (100 MSamples/s) remains unchanged.  However, the device keeps 8 bits (1 byte) samples in memory of the device.  Bus speed is also unchanged, BUT you can extract 100 MSamples/s memory of the device to the host memory (because each sample is smaller).

  Regarding your second question: you can use a step-down converter frequencies more bandwidth with the 5142.   If this isn't a frequency step-down converter, you need set the 5142 with the NOR-Scope pilot (rather than NOR-DAMA).  There are examples included with the NO-Scope driver that illustrate how to program the functions IF the 5142 (examples of embedded Signal Processing.  However, you should first consider the new OR-5663 Analyzer vector signals, which is the device to 6.6 GHz with an instantaneous bandwidth of 50 MHz.

• Trigger the FI - RIO 5641R and digitizer 5142

  Hello

  I am trying to generate a trigger of the my IF - RIO FPGA to start the acquisition on a table digitizer 5142. I want to do with the PXI line, but I don't have the same line in the e/s FPGA (PXIe_Trig0... PXIe_Trig6) and in the range driver (RTSI0.. RTSI6, PFI0... PFI2).

  So, it is possible to do? If Yes, which line should I use?

  Thank you

  I found a PXI-7852R get tested. The problem was in the IF - RIO.

  I found a vi in the 5641 driver to set the direction of the RTSI (entry or exit) lines. The default value is entered, now I change out and it works fine.

  I wasn't a huge problem. I don't understand why we do it "manually" on this card, and why when we are simply changing the node FPGA read/write it does not change the meaning automatically.

  Thank you for your help

• 5142 8/16 / 32-bit

  Hello
   
  1- I works with digitizer 5142 or. I want complex data streams, for which I activated the SDC and the rest of the Pentameters. I want to acquire as binary width vi example in examples of niscope. Now the problem is when I extract the data in the format 08/16/32 bit in 1 d format vi gives error

  Possible reasons:
  Driver status: (Hex 0xBFFA0010)
  Invalid value for the parameter or property.

  Device: digitizer
  Property: Sample binary width
  Invalid value: 8
  Possible values: 32

  State code:-200077

  which is true this works for 32-bit only.

  2- now, when I made the extraction vi fetch 2D 16/08/32 works fine What's wrong with extraction of 1 d? coming out I don't know, but as long as vi is concerned it works well.

  3- when I do not use binary sample width in the property node and go look in the 16/08/32 manually it works very well for 1 d as

  Although 2D... More?

  Hi malala.

  Attached is the same example as above, streams
  5142 complex IQ datato RAM, with the addition of a filtering complex
  through the Digital Filter Design Toolkit.

  The DFD Toolbox
  fact has no support for native data types of complex, but it is not
  problem. To band-pass filter a signal complex to 0 Hz baseband, you
  Just use a model of low-pass filter with cutoff frequency and
  stopband attenuation you want and then use this same design of filter on
  the individual I and Q data stream.

  I also changed the
  front panel so that now it shows a power spectrum, so that you can see the
  the DFD filter effect is to have the IQ data. Since your application
  You must run as quickly as possible, that you might want to delete everything except extraction and treatment, you need to perform on the IQ of the While loop nested data. This includes the calculation of the power spectrum and the graphic representation of the data.

  I hope this helps.

• OR PXI-5142 niScope errors of simulation (0xBFFA4A3B and 0xBFFA408C)

  In development, I'm looking for work with the drivers of the simulation.

  Inside of MAX, I put session pilot "niScope" to simulate with specific driver (I also tried simulate with nisScope and the result was similar)

  Here is the set of instructions that I call:

  niScope_init ("Scope", VI_TRUE, VI_FALSE, & instScope);

  niScope_SetAttributeViBoolean (instScope, "", NISCOPE_ATTR_DDC_ENABLED, VI_TRUE);

  niScope_SetAttributeViBoolean (instScope, "", NISCOPE_ATTR_DDC_FREQUENCY_TRANSLATION_ENABLED, VI_TRUE);

  And NI SPY says:

  > 3.  niScope_SetAttributeViBoolean (0x00000001, "", NISCOPE_ATTR_DDC_FREQUENCY_TRANSLATION_ENABLED, VI_TRUE)
  > PID: Thread ID 0 x 00000520: 0 x 00000954
  > Start Time: enter the duration 19:56:43.495 00:00:00.047
  > Status: 0xBFFA4A3B

  Here's the development:

  Vital statistics: Property specified is not supported by the device or is not applicable to the task.

  Property: Enabled frequency translation
  Channel name: 0

  State code:-200452

  Now, if I enter the string "model: 5142; "BoardTypeXI" or "model: 5441; BoardTypeXI. MemorySize:268435456"in the program of driver installation, to ensure that the simulation is to take the right hardware, when I start acquisition here is the result of NI SPY:

  > 28.  niScope_InitiateAcquisition (0x00000001)
  > PID: Thread ID 0 x 00000778: 0x00000EA8
  > Start Time: enter the duration 20:33:15.452 00:00:00.000
  > Status: 0xBFFA408C

  with the development:

  DDCS more exist in the device is activated.  Note that some devices have less DDCS channels.

  Device: __tp3

  State code:-214233

  Does that mean error? According to the NI5142 specifications, there should be in Quadrature DC as well as the decimation of baseband. What I want is to send a signal IF to CH0 and perform the downconversion quadrature during extraction of signalthen interleaved to complex values.

  Please let me know what I am doing wrong. It is possbile to simulate with specific driver?  I really need it because I prefer to implement on my desk before you try my code our NI PXI-1042 q embedded system.

  BTW, I noticed that if I want to change any other CSD related ATTR say NISCOPE_ATTR_DDC_CENTER_FREQUENCY I get the same error.

  Thank you

• 5142 channels

  Hello

  My question is how to scan data using the channel 0 and channel 1 of a digitizer simultaneously. I did two files of VI for this race on 5142 channels 1 and 2 using two different anttenas, but when I run one another is arrested. or when I try 2 run two simultanoiusly error comes according to which no appropriate handle found and "niscope close.vi" flashes and a VI is stopped.

  Concerning

  MADD

  Hi malala.

  The justification is in the block diagram of the 5142 and specifically the block schema of the OSP.

  Note that in the 5142 CH0 both CH1 are routed to the block of decimation and OSP. See the image below:

  

  Notice now that in the OSP itself, both channels 0 and 1 are used in CDD for downconversion. See the image below:

  

  As you can see, both channels are used for features in OSP even if the source of the data came from a channel of the ADC. For this, we essentially route information ADC0 CH0 and CH1 and perform the operation of the PSO.

  If you want to use CH0 and CH1 independently, you limit yourself to only - decimation Digital Downconversion and complex baseband is not possible.

  Kind regards

• Space unposted on iPhone SE

  This question has probably been asked, but the solutions never seem to work for me. I have an iPhone 16 GB SE which constantly runs out of space. However, it is not because of my own content. If you add up all the elements of storage or use, you get a little more than 5 GB, Messages, Mail, music and pictures included. Yet, it is said more 11FR is used. All the numbers simply don't add up. Once, I restored it from a backup encrypted on iTunes. After all the applications and the data has been restored, I had more than 5 GB free. Over time, this space has fallen to zero. Of course, restore regularly is a pain, especially with the reset TouchID and duty pay Apple.

  Does anyone have an idea how to stop the loss of storage does not happen? My recently deleted photos is empty and there is no other available to the user caches remained. Thanks for any help.

  Apple devices like iPads don't leave caches in the system? Yes or no.  If yes how system caches can be deleted?

  Yes.

  IOS or system caches are called "Documents & Data" or D & D for short and 'others '. They can be seen by plugging your iOS device on iTunes - on the Summary tab down there will be bar display accurately. They cannot be deleted. The only way to reset is to do a system restore. A restore will reduce the size of D & D and others, but they will start to grow again. However, applications have caches that can be deleted. Safari for example > you can delete all Cookies and data. For other applications, it depends on the application.

  The system restore. First save your device via iTunes. Also import your photos on your computer and copy all the data if possible. Reconstruction of the support first test and test. If this does not help, you may need to restore as a new and reconfigure from scratch as the backup may be damaged. It is important to have your photos and your saved data separately from the backup.

  It seems that the problem is worse when I sent a message before the opening of TB, if this message was sent from my cell phone, or TB on my computer application.

  It seems not completely load messages. And then crashes.

  I wouldn't be surprised if there are some files inherited from a previous version of tuberculosis that causes this. I have emails in this app for more than 15 years, imported at the origin of a paid version of Eudora.

  TB has been actually do much better and don't default at startup close if often with recent versions, but seems to have gotten a LOT worse once again, ever since the last update.

• Can I reset my MacBook Air and restore the backup I made before to reduce others' storage space?

  Hello

  so I have the 126 GB MacBook Air. My problem is that the other takes 87 GB!

  So can I reset my laptop and restore the backup later like you do with iPhones to reduce the "other"?

  I guess this could work, but I'm afraid something away...

  I hope that there is someone who can help me!

  Thank you!

  There is nothing necessarily wrong with 'other' as long it's documents, etc. that you need.

  Make a backup and a restore just grow what you have now. I would not recommend it.

  I understand
  Vector signal analyzers OR consist of 2 or 3 separate PXI modules: 1
  digitizer, 1 buck converter of RF frequencies and 1 generator of signals (model 5663).

  1. can I use digitizer and signal
  generator general purpose oscilloscope and generator of signals separately?

  2 may I build my own VSA by choosing
  different combinations of scanners and the signal generators? Or replace the signal
  generator by an arbitrary signal generator?

  3.       I
  intend to buy a digitizer/oscilloscope and an arbitrary signal generator
  analysis of response of frequency on the transformers. Later I plan to
  buy a step-down converter frequency and build a vector signal Analyzer. Is this possible?

  Hello

  The frequency IF the 5660 and 5661 (it's the same thing) is 15 MHz, with an instantaneous bandwidth of 20 MHz. The difference between the 5660 and the 5661 is located in the digitizer that accompanies it. The 5660 uses the PXI-5620 digitizer that has a sampling rate 64 MECH. / s and a buck converter of digital frequency limited to 1.25 MHz of bandwidth. The 5661 uses the digitizer PXI-5142, giving you a MECH 100. / s rate and a PSO allowing digital downconversion circuit and the decimation of the full bandwidth of 20 MHz.

  The common comment in the SBA above is the RF PXI-5600 frequency step-down converter which is a superheterodyne architecture of three floors. OL is for the three stages of this module are auto-approvisionnées in their own country. The architecture of several step allows for rejection of the improved image and filtering at the expensive of a noise floor slightly higher due to the signal path more complex. There also an OCXO on board, this gives him a time reference more precise - noise reduction phase etc. The PXI-5600 by itself is wide from three locations.

  The SMU-5601 since SMU-5663 step-down is designed based on the single frequency step-down converter and resumes from a single location. The celled frequency step-down converter gives you improved noise floor characteristics and a better dynamic range, with the rejection of the image fees, having does not simply because there is only one step. The LO is provided by an external module in this case for several reasons. Have a separate external LO allows more modularity in your system, as well as the ability to share a single LO generator between several vendor-specific attributes. This opens the possibility of MIMO applications. The internal of the NI PXI-5600 LOs are not shareable and therefore cannot be synchronized between several PXI-5600 s. The PXI-5663 (all three modules) takes up the same amount of space in the slot as a single NI PXI-5600 without a digitizer.

  The PXI-5154 is indeed a powerful scanner, given its instantaneous bandwidth of 1 GHz. Remember, however, that the connector Active Directory on this digitizer is 8 bits, compared to the 5622 which is 16-bit. If you need more resolution is of course entirely depends on your application. The PXI-5600, as SMU-5601 is controllable as a buck converter stand-alone frequency using the DAMA API OR. You will need to program your application with the scope API for use with PXI-5154 OR and the API de DAMA. A few other caveats to note is that there is no PSO on the PXI-5154 so you can't enjoy the Equalization filter to correct the frequency of the NI PXI-5600 response. Also, as I mentioned above, the frequency of YEW of the NI PXI-5600 has 15 MHz with a bandwidth of 20 MHz - processor 1 GHz bandwidth on your digitizer will be somewhat of an overdose of the IF signal.

  While you're dead on with the advantage of modularity, I would take the time to really meet your search application and ensure that different choices of module and their combinations to meet these needs.

  Hope that helps!
