  1. Hi Friends, I recently moved to new company where i am finding that they are not using LabVIEW but Test stand. I never had a chance even to discuss about about NI-Teststand so far. so time to move on to Test stand now. I have few questions to discuss here.. 1. Is Test stand is completely new programming language than LabVIEW? 2. How to convert Test stand program to LabVIEW and LabVIEW to test stand back? Regards, Jaikanth

    Hi Hoovahh, good introduction.. i will attend the arduino workshop on 21 and 22nd sep. I believe i will get more info on this subject. thanks.

    i have been seeing many discussions about "Arduino" and i have no knowledge about it. i am planing to go for a workshop soon. before the workshop i want to have little knowledge in this regard. Tried to search in labview forums that took me " NI LabVIEW Interface for Arduino Toolkit".page. I checked arduino's official website , still i need some understanding for effective usage.. what are the applications area where i can implement Arduino with Labview? please advise. thanks. note : i am reading "https://decibel.ni.com/content/groups/labview-interface-for-arduino" link now. is Arduino is having different standard hardware worldwide? pls help.
  4. Oh Yes .. i found the way to solve. i right clicked on the "conflict" vi and selected "resolve conflict" and choose the right path for that vi. now everything alright.
  5. i am seeing as "conflict" in one of the sub vi in the project file. i do not understand why it showing like this? please help .

    thank you todd !

    In my production pc i have one ethernet port in which i have connected to DAQ modules. i want to connect my pc to server too for saving my log files. Any hardware i need to install to have two ethernet ports (one for daq and another for lan)?
  9. Hi i want to launch the LabVIEW program automatically whenever windows starts.(windows xp or 7) The program must be running at background so the computer operator shouldn't recognize that it is running. if windows task manager not detects that is very good but not mandatory. thanks.
  10. Hi All, Currently Test logs are saving at local hard disc which i want to move to server location. (cut and paste) for some reasons i prefer server location instead of ftp. for example:- From (the source path) D:FunctionalTestTest Systemslog to (the target path where i want to move log files) Server1FunctionalTestlog any way can i incorporate the server's username and password into the LabVIEW code, so that the program can access the server for moving the files? The test operator login credentials are not having privilege to access the server where as the program need to do access for storing the files. thanks.
  11. As possible as the comments neatly written and "smaller" than coding diagrams.it's OK for me
  12. I have a project where main VI is not protected. The main VI consists of several sub vi. Many vi are placed one in to other. I have to make sure all vis are unprotected. how can i know all vis are un protected? any shortcut method available instead of opening all vis block diagram one by one ?? thanks.
  13. Hi Tim, Thanks for your valuable input!
  14. No, i'm not measuring the constatnt voltage. the nature of the signal is DC Pulses approx 4 pulses in a second. though the scope is showing the waveform as expected i want to cross verify the peak voltage through DMM. The DMM i have is Agilent 34401A. i did an experiment like below :- taken two different manufacturers of 100:1 probes. Probe 1 (100:1) (Manufacturer unknown) connected to oscilloscope : result as expected. connected to DMM : Peak voltage detected to approx 30 V DC Probe 2 (100:1) (PMK PHV 1000) connected to oscilloscope : result as expected. connected to DMM : Peak voltage detected to approx 6.1 V DC I Intended to use PCIE6320 as my DAQ. Before connecting the signal to DAQ i want to verify the signal is in accpeted range. thanks.
  15. Hello All, I'm using Agilent MSO 6052A Oscilloscope for capturing the DUTs waveform. I downloaded the driver file for this scope from NI site and i found few esamples. When i try to execute any example program, that made oscilloscope in default settings. The is Time base and voltage per division, etc settings are changing towards "Autoset" which i do not want to do it during fetching. Seems that "Initialize" function in the example vi, making the Scope in autoset and i'm not able to modify/ see the settings as like i want. if anybody using any VI that fetches the waveform as it is please share thanks.
  16. Hi Tim, I'm sure that is 100:1 PROBE Setting is selected at oscilloscope. Oscilloscope is reading right as expected but DMM not, It is very strange for me.
  17. please do not forget to give your feedback ! me too want to go one !!
  18. Hi All, I have an observation of voltage measurement between Oscilloscope and Digital Multimeter. The voltage is shown properly as expected at Oscilloscope but the digital multimeter shown higher.(10 times more) Normally before connecting the DUT Signal to DAQ i will verify at Oscilloscope and DMM. I got the difference between DMM reading and scope reading. is this because if Input impedance of these devices? From the manuals i see there is no difference in Input impedances. Is it neceesary to use "Input impedance adapter" before feeding the signal to DAQ? I am using 100:1 probe for voltage measurement. (Voltage range if 350 V) is Input Impedance depends on the cable we use? because in oscilloscope we can select probe nature like 10:1, 100:1 ,1:1 etc ... but in DMM it is not possible.
  19. Help me to understand what is the meaning of source digital output and sink digital output? for example PCI 6516 is 32 Source Digital output device PCI 6517 is 32 Sink Digital Output Thanks. Happy New Year to all !!
  20. Considering cost factor, Industrial PC costs double of Normal PC - Seems NI Industrial PC is triple of Normal PC ! Based on my experience depends on application and environment situation one can go for Industrial PC if necessary. Otherwise no need of Industrial PC. (It's my thought). I unnecessarily gone for Industrial PC for couple of my projects, and i'm thinking normal assembled computer can do the work same. The only difference i find is that you can place industrial PC horizontally (Rack mount) and assembled market PC will stand vertically inside your test cabinet.
  21. i am successfully able to acquire the DUT's signal as expected. (the waveform is like the attachment). the task is that i need to measure the time for four cycles of waveform. as attached in the picture, the four pulses time period is approx 950 m seconds. any express vi available to analyse the waveform, resulting like i need? thanks.
  22. what is the difference between VISA clear and VISA Close?
  23. Dear Crelf, I did the same way you explained. I'm using USB-rs232 Convertor. I changed the visa resource name in the code but it not worked. i do not know why so... i re-write new codes for serial communication part and updated my existing code. why i asked serial to GPIB convertor is, in that case i no need to change anything except making sure the device number in MAX is matching with softwar VISA resource name.. thanks for the reply.
  24. Hi, I'm using an ATE in which i'm controlling many measurement devices thorough GPIB interface only. One of the instrument - Voltech- PM300 Power Analyzer gone bad and i have a standby Power Analyzer. Unfortunately the standby instrument doesn't have the GPIB interface but it consists of RS232 interface. If i use RS232 to GPIB convertor, does this solve my problem? Any settings need to be done in program? How i can assign the GPIB Device No? does this reflect in MAX? I never used this RS232-GPIB Convertor, but i want to make sure everything is fine before buying. please advice. thanks.
