Sachant que je vais connecter une SMU sur mon PC pour faire l'acquisition de données, est il préférable d'utiliser un GPIB USB HS ou un GPIB USB HS+ ( contient un analyseur) ?
Est ce que cette nouvelle fonctionalité du GPIB HS+ ( analyseur intégré ) va bien marcher sachant qu'actualement j'ai une version sans analyseur et que ça fonctionne super bien.
Merci d'avance.
I am using the Temptronics ATS-545 M9 instrument. I am in currently in process of automating the Thermo-stream. To do this activity we need windows IVI driver for Thermostream - Temptronics ATS-545 M9. I heard Instrument model TP04310 and ATS-545-M-9 both are same. I found CVI drivers. But i need IVI C/IVICOM drivers for my purpose to integrate to python code.
Thanks in advance!!
Buenos Días, Necesito algo de ayuda, estoy trabajando en un proyecto donde necesito comunicar un baño termostático a un PC mediante puerto rs232, y poder realizar el control del mismo, este equipo trae un software que realiza el control pero no es lo que yo necesito, además, tengo un indicador controlador de pH, el cual monitorea el pH del proceso y me permite controlar el pH del medio mediante una señal electrica que me acciona una bomba dosificadora, este equipo trae una salida analogica de 4 voltios mediante la cual se puede monitoriar la variación del pH, mi intención es unificar en un solo programa (VI) el control del baño termostático, la lectura de la temperatura y el indicador controlador de pH, pero no he podido realizar la comunicación mediante el puerto rs232.
Agradeceria algo de ayuda.
Un saludo,
Douglas
Hello,
my c++ program is using instrument drivers that return viStatus.
Where can i find a list of what this error means in detail?
In this case the returned number is -1074130544.
In the Visa help i only find errornumbers that start with -1073807xxx
Thanks

Hello, anyone please help me how to connect to a bluetooth module(here i'm using HC-05) with Labview.
without connecting any bluetooth adapter to the pc.I have connected two bluetooth to two hardware devices,
so that i need to read the data from both the bluetooth modules,and it will be stored in a file.
Please anyone guide me how to do it.Is anyone having the Vi,please mail me p.chandu.416@gmail.com.
Thank you in advance
I would like to perform a screen capture from oscilloscope DPO7000 ?
file -> Save as --> screen capture. and fix extension in *.png.
i do the acquire waveform but it's not interresting for my board test.
Have you an idea ?
thank you
I have a device designed around the 9914 ASIC, it hase been used successfully for several years however when trying to detect the device in MAX it detects the Listen command but does not receive any information. It appears max simply sends the listen command to detect if something is on the bus at that address. Can somone provide a method of detecting this operation to enable the interface to correctly handle this scenario. Note that the unit was used in an ATE which did not perform the listen activity described so I am confident that the implemented design correctly trnsfers data.
I believe that I have the latest drivers for Labview, and Windows can read them fine with no problems. However, they don't show up in NIMAX. Not sure what else to provide here.
I also can't find the ausbtmc.sys file, which I think I need.
Hello everybody,
I'm working in a program with LabView 2015 that control 2 instruments, the Rohde & Schwarz Smiq02b signal generator, and the Agilent EXA n9010a spectrum analyzer. I'm using the Agilent-82357B USB/GPIB cable to connect my laptop with these two instruments (PC -> EXA -> SMIQ). I've also installed both instruments drivers from their official websites.
The program worked properly until I had to format my computer and install LabView again but something is wrong now.
The problem comes when I run the program, the SMIQ02b can't initialize, the program stops and opens a new block diagram window. This block diagram belongs to a block of the instrument driver, inside this block diagram there is a VISA Write block blinking.
This only happens when I'm initializing two instruments in the same program, if I create a new VI and use the SMIQ only, I have no problems.
I don't know what's going on, It's very strange that it worked well before and now this happens.
This is what I've installed in my laptop:
- LabView 2015
- NI Device Drivers (Included NI-VISA 14.0 and NI-488.2 14.0)
- Agilent IO Libraries Suite 17.1 (Configured as secondary VISA)
- NI-VISA Passport for tulip ON
I'll be very thankful if somebody could help me with this.
Thanks!
Greetings,
I'm writing software to one simple test system which uses PXI-2575 to connect measurement device (e.g. DMM) to measured channel. I want to connect e.g. CH0 to CH4, but whatever I try, an exception occurs. Is it really true that I need to use NI-Switch to perform what I need by controlling individual relays?
This might be a newbie question but couldn't find an answer from google, IVI-, or NI-website.
Hi,

Hello everyone,
I’ve encountered an issue with using the Basler camera (Basler ace acA2040-180km NIR). For some reason I am not able to establish/maintain the serial connection to the camera using e.g. Pylon viewer. Other than that, the camera works fine and I can acquire data as usual, however I cannot change the parameters like exposure time or area of interest.
Used Hardware & Software
Hardware
Software
Where it all started
The whole imaging system is connected to an isolation transformer as a safety precaution. During standard image acquisition, power went off in the lab thus shutting everything down. After the power came back online, I started the computer and wasn’t able to establish a serial communication to the camera anymore (using Pylon viewer from Basler).
Troubleshooting so far
When I use the Pylon CL Configurator, it detects the FlexRIO port but gives a message: “The stream is not a CLPort registry stream since it is missing the magic GUID in the first line”. And as an intermediate user I have no idea what the message is about.
Long story short
The serial communication between the PC and the camera is not working and for some reason Pylon viewer is not able to detect the camera. I’m so baffled myself why this is not working so if someone can shed light on this mystery I'd be grateful.
Best,

HI, i'm a beginner, i have a Stm32f401 nucleo board connected to my pc with a USB cable type A to mini-B, can i comunicate with this board with LabView?
can i read in LabView signals from this board? (like the pressure of the button that i have on my board, and can i count it?)
have i to install some drivers, or something else ?
THanks for the attention.
Hello,
I have a question on NI-MAX and Instruments.
When I open NI-MAX, it does see PCI-GPIB "GPIB0" under Devices and Interfaces, but it doesn't communicate with any my instruments like Agilent 34970A or California Instrument CSW5550... I tried to replace different GPIB cables and GPIB cards, but still not communicated. Please help
Thanks

Hi Everybody -
I am running LV2015x86 on Win10, connecting to a Tektronix oscilloscop, MSO 2014B using NI-VISA 15.0.
The MSO has the latest firmware (v 1.52) and will work for me, through configuration of timebase, channels, etc, and reading waveforms and various measurements. All works fine.
However, there will occur an error while reading from the MSO (measurements, no waveforms) wherein an error is flagged and it will no longer re-connect. The error I receive and capture shortly after it occurs is:
Hi im beginer to labview and doing serieal interfacing Agilent MSOX-2014A oscilloscope to pc.could you give me some information how to controll the time base and setting?
I have a Compact Rio 9068 running the NI Linux Real-Time OS. I wanted to attach a GPIB-USB-HS+ to add a GPIB interace to it. My Problem is that I cant seem to install NI-488.2 on the 9068. I have it installed on my computer, and in MAX I have the option to install 488.2 on a PXI controller I have, but It will not give me the option to install it on the Compact RIO chassis. Is there no NI-488.2 for the NI Linux Real-Time OS? I cant seem to find anything about it in any documentation.
Thanks
Mike
Hello to the NI-Community,
We are looking for temperature sensors in order to measure water temperature (from 5 to 50°C) in thin tubes. We are thinking about using a T-piece in order to bring the sensor perpendicular in the tube. The sensor should have a diameter smaller as 4millimeters in order to get into the tube opening.
Can you please help us to find the right one? Somehow I could not find the informations I was needing on NI products website so I am trying it this way.
Thank you in advance.

Hello everybody,
I´ve been trying to generate a single burst signal consisting of a sine with modulated amplitude. I can generate either the burst signal or the sine with the modulated amplitude, but separately. My gold is to merge the two steps to produce the kind of signal that I want. It should look like the attached figure. My question would be if that is even possible to make with the Aligent 33120a, and most importantly, how.
I´ve been trying to make a VI in Labview to produce this signal, but it doesn´t work. But i guess that is a question for later.
Thank you for your answers
