python api


I am trying to read XL2 SPL measurements via usb, but only ECHO command acually returns something, all other commands return just blank.

I used the skeleton code from XL2 Remote Measurement Reference Manual (

I tried it on windows 10 as well as on raspbian stretch. I am using python 2.7.

Any help would be appreciated.


Hello Nejc,

does your XL2 have a "Remote Measurement" option installed? If not, the XL2 will react only on a very limited set of commands  like “ECHO” or “*IDN?”

Thank you Gregor, I received XL2 from a customer and wasn't aware this was a seperate option.
