Hi Muhammad, Please refrain from posting comments about immigration visas. This software library supports driving an oscilloscope using Virtual Instrument Software Architecture (VISA). It has nothing to do with a issuing a visa.

The first step is to get an update on your application status. Most visa processing authorities provide online tracking systems where you can check the current status of your application. For those specifically dealing with Qatar family residence visa processing time , ensure you have all necessary details at hand, such as your application reference number or personal details, to access this information.

I have implemented Sharky's suggestion in version 2.1 (JVisa version 0.7). That is the only change I made apart from now using Apache NetBeans 11 as IDE.

Updated with the fact that the IDE in use is now Apache NetBeans 11.

JVisa.openDefaultResourceManager now allows also a return status VI_WARN_CONFIG_NLOADED apart from VI_SUCCESS.

Thank You for library, I use it with my Siglent scope and signal generator devices. Found that sometime on openDefaultRM VISA can return not only VI_SUCCESS, but VI_WARN_CONFIG_NLOADED which is not error, just warning. After this visaResourceManagerHandle is zero and openInstrument don't work correctly. Proposed fix: public long openDefaultResourceManager() { try { LOGGER.info("Open resource manager."); pViSession = new NativeLongByReference(); VisaLibrary.ViStatus visaStatus = visaLib.viOpenDefaultRM(pViSession);...

Hi Charles, actually, I have to revise my previous statement about JVisa not supporting more than one instrument. Try something like this: JVisaInstrument instrument1, instrument2; JVisa visa = new JVisa(); long visaStatus = visa.openDefaultResourceManager(); if (visaStatus == VisatypeLibrary.VI_SUCCESS) { instrument1 = new JVisaInstrument(); // The instrument string is just an example. instrument1.openInstrument("TCPIP::192.168.1.106::INSTR"); instrument2 = new JVisaInstrument(); // The instrument...

Hi Gunter, Thanks for your reply and willingness to modify your code. I am using IEEE on Windows. If it is not an† imposition, may I ask that you alert me once you have made the code changes. I will then download, test and give you feedback. Again, thanks for a great product and you willingness to support it.

Hi Charles, I have never tried JVisa with more than one oscilloscope connected through ethernet. Looking at the (my |: ) code I think I can see what the problem is. The code makes the resource manager handle variable protected, so JVisa can currently only set it by opening / instantiating a resouce manager which would then only allow one instrument per resource manager. So, I expect that the second time trying to open a resource manager after instantiating a second JVisa class an error is returned....

Good day, I am able to use the library to communicate with a R&S NAP power meter. In the system I have more than 1 such device but I dont seem to be able to initialize and connect to the second device. Can you assist me which some advice or sample of using multiple devices with this library. Many thanks -- Best Regards, Charles Hill May your basket always be filled with bread, and your family filled with joy! This e-mail is private and confidential between the sender and the addressee.

Hi Charles, great to hear that someone other than me (at some of the labs at Colorado School of Mines) is using the driver. Do you run your app under MS Windows (TekVisa or NiVisa?) or Linux (libreVisa)? Cheers, Gunter

Update. I got this working and it seems to work fine.

Hi, I have a VISA compliant Agilent Signal Generator (N5171B) and an Agilent GPIB card (82350C) and will use Keysight IO Libraries Suite 17.0. Can you let me know if I will be able to use this library to interface my software to the generator.
