content: Hello,Does anyone have available the LabView driver for R&S CMU200 instrument.This location here leads to nowhere as this driver is not available to download from R&S anymore:http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_model_id=1643I really want to setup a small testing program for FM stereo + audio measurements. My other option is to use Matlab for which the driver is available , but I hate the app designer in Matlab

content: I have never used the instrument you mention. Doing a quick search, it seems there was a lot of discussions about this instrument. NI used to provide drivers for it. What all have you tried? Have you contacted R&S? NI? What version of LabView are you running?

content: https://forums.ni.com/t5/LabVIEW/LabVIEW-CMU200-help/td-p/690258From above, it appears NI distributed it with LabView 7.1. If you have the original installation disks, you should be able to get it from there. If not and your license is current, you should have access to it from NI's site. If you are currently not under contract with them, you may need to find someone who archived the older disks.https://xdevs.com/doc/R&S/R%26S%20CMU200%20CRTU/CMU_Manual.pdfFrom the manual above, it looks like it was from mid 2006. I home I have 5.0 and 6.0 but I suspect these are too old but will check 6.x For work, we dropped all of our LabView contracts when they decided to change the terms from perpetual to rental. So I don't have access to their archives.

content: Yeah NI does not support this driver. R&S is a dead end when it comes to obsolete industrial equipment support. I might have to dig some old workstations at work. Some of them probably have LabView 7.1.

content: I looked around and found an 8.5 install but it does not appear to include it. I'll check later to see if my last version of 6.x included it.

content: I checked 6.1 and it does not include it. I also had 8.1 but they had removed all of the third party drivers by then. Sorry I couldn't be of more help. I think you need to find that 7 install set. Good luck

content: Yeah,I could not find anything lower than LV2011. I guess the only option is to look for eBay sales of old software and hope for some luck.Thank you for the efforts.

content: Assuming you want to use LabView rather than Python because you know how to use it. Another option, if they had an older model that used the same basic commands and interface, you may be able to use that as a starting point.What physical layer does your instrument use? GPIB?

content: I use GPIB. CMU200 has a comprehensive user guide for SCPI programming. Eventually I will have to roll my own driver.

content: The CDM 80 was GPIB. I tried to import it into 2011 but no luck. I would have to install older versions of LabView and port it. Certainly possible if the command set was close enough to use it as a starting point. My guess is you will have to do this with the 7.0 drivers as well.
