These instructions should work for the 3 GHz spectrum analysers as well, however, they have not been tested and there seem to be some variations as to how different models of the Rohde and Schwarz spectrum analysers interpret these commands (or at least different generations).
Once the instrument has the ethernet connected
telnet spechb.phys.utas.edu.au 5025
No password is required and you can then start entering commands to the spectrum analyser. This interface has some limitations in that no error messages are returned, so if you type an invalid command, nothing happens, but there is no indication (if you aren't looking at the spectrum analyser) that there is a problem NOTE: It seems that there can only be one active connection at a time, so if valid commands are performing as expected, make sure that there are no competing connections:
To look at the range 1-3 GHz
To query settings replace the value with a ? right at the end of the command
To set the reference level to -60 dB with a 20 dB range
To look at maxhold on trace2 and the average of 1000 sweeps on trace 3
