Hi All,
I use R&S instrument(SG and spectrum analyzer) to measure LTE-TDD EVM,(Center Freq: 2.6G, power: -30dBm)
But I am at a loss that I get the the value 87.18(EVM PDSCH 64QAM) , it beyond the limit 8.
I donot know how to make it, can anybody do me a favor?
And BTW, who can provide the remote commands for measure EVM, I want to use Labview to control it instead of manually.
Thanks a lot

Hi Amanda,
Which specific Rohde & Scwarz instruments are you using? We have instrument drivers at ni.com/idnet for a number of devices, including some R&S SG's and analyzers. You can also download LabVIEW drivers at their website here. These should help you interface your instruments with LabVIEW. You should also make sure that you have NI-VISA installed on your machine. You can search for, download and install the appropriate version of this driver here.
Hope this helps!
Regards,
Stephanie R.

Hi Amanda,
please find attached a simple example to get started. This one works fine with e.g. FSV and SMBV100A.
