# Using a RALF workstation¶

RALF stations are available at ISAE-Supaero, they are provided with GNU/Linux Debian Wheezy or Xubuntu 14.04. This documentation is a short getting started guide in order to start working with RALF.

## Login, home and network shares¶

You must login using your ISAE-Supaero account after choosing your graphical environment (GNOME Shell, GNOME Classic, Xfce). At your first login, once the access is granted by the LDAP server, a home directory is automatically created locally in subdirectories of /home.

Notice that networks shares are not available through NFS due to delegated administration of the computers. However, it remains possible to use network shares through SAMBA (use for example Gigolo).

## Driving USRP hardware¶

warning. Beware of the transmission power !

• Start transmitting only if 50 ohm termination is used (antenna, dummy load, loopback interface...).
• If you are using a loopback interface, do not forget to connect a 30 dB attenuator.
• Respect the regulation.

You can start by running and analyzing examples as described here.
