Rigol software files are downloaded in .rar data containers or .zip compressed files. The files must be unpacked or unzipped before installation.
Ultra Sigma must be installed before any other Rigol application, except Ultra Wave.
To open a Rigol software application after installation (excluding S1210, S1220, S1501 and Ultra Wave)… Open Ultra Sigma > Connect your instrument > Your instrument should appear in the Ultra Sigma window (see the orange box in the picture below) > Right-click on your instrument (the orange box) and select the Rigol application.
