• Agilent 33250 A driving, how to avoid frequency rounded up/down

  Hello

  I want to control an Agilent 33250 A generator using LabVIEW to obtain different waveforms with a specific frequency, amplitude values. I use Agilent 33XXX Series.lvlib: Configure Standard Waveform.vi

  My problem is that when I give a value of frequency of 79 999 Hz 996 (79. 999 996 MHz) for example, the program will round the value to 80 MHz. How can I give a frequency value, as above, without rounding upwards or downwards?

  Thanks in advance.

  Look at the VI and see how is the string format. The result of the conversion of a string to the probe and see what happened to the instrument.

• Problem with PCI-GPIB card control Agilent 8648 D generator interface

  Hello

  I downloaded the driver Plug-and-Play (project-style) for Agilent 8648 A generator of signals. I use LabVIEW 2011.

  I open the file project and resource VISA name menu, select COM1. Note that I use 82350B of the PCI-GPIB Interface Card.

  I run the project, and I get timeout error.

  Is there a problem in the PCI-GPIB interface or am I missing something? I'm new to LabView and PCI-GPIB interface, and I'd appreciate any help.

  Thank you

  Given that you do not use a NI GPIB, go to MAX, select software and NI-VISA. In the right window, click the Options of VISA, and then select passports under general settings. Check on the passport of NI-VISA for Tulip.

  I'm assumimg you loaded the driver of Agilent and tested the communication with their software.

• Generator functions agilent modulated the amplitude of the voltage so that the signal

  Hello

  I'm new on the Labview.

  I need to provide a series of tensions with increases step on my device and it repeats again and again.

  For example, (5V 0V to 10V 0V 0V 15V) * 5 times

  In the past, I turned down on the generator Panel of Agilent 33220 functions by myself.

  It's stupid, so I will try to use the Labview to do the same.

  I have download the Agilent 33220 Vi function generator has and write a loop for to do this. It can work.

  But I found a problem. Each change of amplitude voltage, generator Agilent 33220 A functions will cease to exit and then output the new value.

  Because this short period of no output voltage, the dynamic behavior of my device will be destroyed.

  How can I do?

  You made a classic mistake. You have placed the Initialize and close inside the loop. The Initialize will, by default, perform a reset feature, which disables the output. Initialize outside a loop, do your stuff inside and close the loop.

  Regarding your code: I strongly recommend looking at the model of ramp function. It seems you want to increase the parameters of voltage to zero between the two. This can be easily done by creating your rising tensions ramp and then creating another matrix of the same size zeros and interlacing then the two tables. This will give you a complete range of voltage values, without to need two loops and determine what step you are on, etc. etc. For example, the following code will give you 5, 0, 0, 10, 15, 0 sequence fairly cleanly:

  

  In addition, never perform a comparison of equality on the floats. If not, you owe me nickel one another in my retirement fund.

• Why do I get error 200524 for the generating function 2 code example?

  I get the following error message:

  Error-200524 occurred at the generating function 2 channel_lv86.vi

  Possible reasons:

  Scripture cannot be performed because the number of data channels does not match number of channels in the task.

  When writing, provide data for all channels in the task. You can also change the task so that it contains the same number of channels as the written data.

  Number of channels of task: 1
  Number of data channels : 2

  Task name: _unnamedTask

  When I downloaded and ran the 2 channel here code: https://decibel.ni.com/content/docs/DOC-3545

  I have a card pci-e DAQ 6259 and a block BNC-2110

  Why I get this error?

  When I open the VI I selected ' Dev1/ao"under physical channels. I tried all the other options (a0 - a3) which gave the same error message.

  If you have 2 channels in your data (as indicated in the error message), then you must choose 2 channels in your task control (the error message says that you have selected only 1.)

  You saw in the example how they were able to identify the 2 channels of analog output?

• Assistance needed for the registration of the application and store the values in a table

  Hello

  Hope that this explanation is not confusing. I explained my application you want in the text below and also attached a skeleton VI + screenshot hoping that he will clarify

  I try to do a VI that does the following:
  1. some code (blue Subvi) runs every 200ms
  2. every 200ms, a random number is generated
  3. the random numbers are stored in a table in intervals of time s 0.8 ("iterations")
  4. at any time, the (blue Subvi) code needs to have access to the random numbers generated in 'the previous iteration.

  To clarify, the iterations are as follows:
  Iteration #1: 0 - 1.8 s
  Iteration #2: 2 - 2. 8 s
  Iteration #3: 3 - 3.8 s

  Iteration #4: 4 - 4.8 s
  ..
  And so on...

  So for each iteration: the blue (Subvi) needs to have access to the random numbers generated in the previous iteration, for example:

  Iteration #1 (0 - 1.8 s): The blue (Subvi) Gets an array that contains only the zero (random numbers are recorded for the first time)
  Iteration #2 (2s - 2 8 s): The code gets an array containing random numbers of iteration #1
  Iteration #3 (3 s - s 3.8): the code gets an array containing random numbers of iteration #2
  Iteration #4 (3 s - s 3.8): the code gets an array containing random numbers of iteration #3
  ..
  And so on...

  At any given time in time;
  -The code gets an array that contains all the random, recorded during the previous iteration numbers
  -Values since before her previous iteration are ignored and not stored anywhere

  Thus, for example, to the #7 iteration:

  -The values during the iteration #6 are made available to the code in the form of a table

  -Values of #1 to #5 iterations have been deleted and not stored anywhere

  It is important that all values since before recording the previous iteration are deleted because they are not necessary because VI actaual will work for a long period of storage of numbers a lot more than I have indicated here

  Screenshot of the skeleton VI:

  

  I tried to play with the paintings, the structures of the case and the registers at offset, but everytime I try I get something wrong

  The skeleton VI is also attached (Iteration_VI and Code_SubVI)

  Any suggestions?

  Thank you!

  Yes, I agree that you need help.  First of all, you really do need to learn more about LabVIEW - spend a few hours with the tutorials, such as those mentioned on the first page of the Forums.  Oops - links to the tutorials which had been present for years seem to have been moved "elsewhere" with August 2016 LabVIEW community reorganization.  But look for them...

  Here are a few screws that basically implement what I described above (with some minor modifications).  First of all, this is a Top level VI which runs at 5 Hz (200 msec waits).  It starts with an array of 5 elements of 0, then once per second, this is replaced by a table of random numbers generated by the Random 5-table sub - VI 5 elements.  Note that I do not use a loop timed - those who are really designed for LabVIEW RT, but use the simplest functions on the Palette of the timer.

  

  Can't you see how that works?  The array to initialize on the left begins you with a table of 5 elements of 0.  The Timer inside the loop, it runs at 5 Hz, 'Index' counts 1, 2, 3,... to tell you where you are, and 5 shows you everything that lives on the shift register.

  Now sub - VI Random 5-table is supposed to do the following - if she was called to 5, 10, 15,..., it must return a (new) array of 5 random numbers, otherwise, it must return the array that was passed in.  So if all "works", table 5 shows 0, 0, 0, 0, 0 for the first second, a table at random for the second second (which is not superfluous!), a different for the third random picture second and so on.  I have already said a way to build this, but I chose a slightly different method (equivalent).

  

  Whenever it is called, a new random element is generated and added at the end of a (growing) random table stored in the shift register.  If size become 5, we send this Random-table-of-5 out through Out table and reset the register shift to an empty array.

  The case by default (when the size is not equal to 5) is shown below - we just return the array of entry to and accumulate new random table in full growth.

  

  These code fragments extracted from VI.  If you have LabVIEW 2016 (see the "2016" at the top right of the image?  This shows that it is a snippet of code LabVIEW 2016), you can open a blank diagram and drag this image, where magic OR converts it to a VI.  Otherwise, the code yourself and try out it.

  Caution - it is designed to run once.  If you run the program of high level, a second time, you may find that the new Random 5 - table appears to 0.4 ", 1.4", 2.4"(instead of 1", 2 ", 3").  I leave as an exercise for understand you to (a) why he is and (b) fix the code.  If you can't do that, then move an another 3-4 hours with the LabVIEW tutorials (or start playing with this code, edit it in some small way and to understand how it works).

• Agilent 33250 has synchronized with DT9812

  Hello everyone,

  I'm trying to control two devices (Agilent 33250 A and card DAQ DT9812) synchronizedly using LabVIEW.
  I need excite a transducer using an arbitrary waveform generated by 33250 A burst mode with its frequency swept KHz x to Y KHz with a given increment. Breakup of period and number of cycles should also be adjustable.
  I am trying to send orders for the generator of signals via port GPIB using LabVIEW VIs.I have the necessary drivers. (Config Burst Modulation.VI under "ag33xxx.llb" and Agilent 33XXX series generate Arbitrary Waveform.vi under "examples" in the attached file) but I don't know how to combine these two.
  I contacted the instrument without any problem and I can take any form of arbitrary wave I want. I can also put the generator in burst mode, but I have to be able to do in a single VI.
  After that, I also need to synchronize the process such as the each time that the frequency of the waveform changes, data is acquired by the computer. I have the LV-LINK to control data acquisition card. I'd appreciate any help that gets at least started me off.

  Thanks in advance

• Windows Live Mail trying to publish "an album" and cannot complete

  I'm stuck. My Live Mail trying to publish an album and obviously cannot complete. I went to the Outbox and delete all emails (some with photos) who were in the queue.

• Report function and calculation

  I tried to use Query.MyField, generator of reports still doesn't like it give me ColdFusion does not recognize.

  I need to have the field calculation as

  for my summary on the ground and the need to change color if necessary.

  Report Builder supports the code side client as Javascript to change behavior on the client side?

  Your information and help is much appreciated,

  Kind regards

  Iccsi,

  Unfortunately, the Report Builder does not provide a way to access field properties and etiquette during execution.

  The only way to make a field label/change its color based on a value is to create multiple labels, on the other; then use the property ' print when Condition "of each label to determine which is visible for a given condition.

  After a hard drive crash and recover most of my files on an external hard drive which eventually became my only internal, but because I live on an island in South America and there's hardly anyone on the island I live who can help other that a friend, I took a trip to Miami to visit the genius bar and they did a new install of Capitan which I don't really like by the way.  In any case, I though I had lost all my iPhoto library, but I managed to find my photos. Only now I have two libraries... the iPhoto with images from my Photos on Capitan and 8 years.  Is it possible to consolidate them in a library?  And can I still use RAW to be able to edit photos? aIso, y at - it a tutorial for the Photos?

  In the future more facts and less editorial help here

  SO now, we know all about how you feel but nothing on your system or your problem

  What version of El Captain do you have (10.11.3 is the current version with Photos 1.3)

  You cannot merge libraries without third party software - Photos of power can merge pictures libraries

  You can migrate iPhoto libraries to libraries of Photos by dragging Photos icon in the Dock

  When you first launched the Photos it has migrated the last used for Photos iPhoto library

• WiFi for computer laptop HP ENVY 15 and Ethernet connection problem

  Hi, a few months ago, I brought a HP ENVY 15 Notebook PC running windows 8.1. It is connected to my wifi with Ralink RT3290 802.11bgn Wi - Fi adapter. My modem is a Technicolour TG582n 2 Wireless ADSL + with wireless 802.11 b/g/n compatible.

  As soon as I got there I noticed a problem of internet where I would be able to connect to my home WiFi network and get full reception bars but would have a hard time to access Web sites on web browsers such as chrome, mozilla and internet explore pages takes some time to load and eventually reached a page "this webpage is not available" (for chrome). This problem seems to occur only with my home network as it can connect to public wifi and my wifi friends and yet I have many other devices such as laptops and other smartphones connected to my wifi that did not at all have poblems with internet and it just seems to be mine. When I connect via ethernet I get good connection for about 10 minutes and then I was completely cut off. However, I can upload a file via the wifi ok if I can get it to start and I can play a game online well enough but often disconnected after an hour or two.

  I checked for new updates of pilot, but they seem to be up to date and im do not manually downloading and installing one on the hp site but I tried (I did probably wrong). I ran the diagnostic function, but it cannot detect all problems. I looked around the internet as well, but still havn't found a solution.

  Also I got the laptop sent back and received a new but the same problem persisted and as I walked through the process of the person I was talking to a admitted that I had a problem like they remote limited from my laptop for a little for the access problem.

  Please help, I've had this problem for a month or two now and is really becoming a problem since I use my laptop computer for purposes of requiring home internet work.

  Thanks in advance and I hope you guys can help!

• pure example to compare the performance of reading for a local variable, a declarant and a queue element (looking for)

  Dear users,

  I came across an example of the operation and the disadvantages of using a local variable, a declarant and a queue for the collection and handling of data these last time. But I can't find him.

  I try to describe what and I hope someone can give me a hint:

  A sinus values were generated periodically and were sent to an indicator, a declarant and a queue. In the other loops, the local variable (of the indicator), the authors of notifications and of the elements of the queue were plotted graphs. Time of the playback loop loops can be set separately for each of them and depends on the sync settings (time: equal to the generator, half of the generator and copy of the generator), we can observe omitted elements or duplicate. Very useful to observe the behavior of loops in a local variable, a declarant and a part of the reading queue.

  Does anyone have an idea where this VI is placed, please?

  Hello ghighuphu,

  Do you mean this example?

  With the help of local Variables, queues and notifiers to synchronize data with parallel loops.

• drivers LabVIEW for agilent e4432b, cannot find the way to control multitone?

  drivers LabVIEW for agilent e4432b, cannot find the way to control multitone? How to deal

  Hello Brownheart,

  Drivers for the instruments aren't supposed to cover all applications use of instruments, only for the most common uses. No matter if multitone is a common use for this instrument, a brief review of the functions available in the driver does not have this feature.

  What you have to do is to create your own config VI using the information of the use of the programming unit. Is not ideal, but at least the driver NOR provided gives you a starting point for adding this feature.
