The security concept of the R&S SMA helps you to protect your instrument against uncontrolled access and changes. All provided security services require that you enter the security password.
- Password management secures controlled user access to the instrument
With the two-step password concept, you can assign a user-defined password for the operating system, as well as a security password for accessing the mass storage of the instrument.
For more information concerning the security password, see the description Resolving Security Issues when Working with an R&S SMA. You can find this document on the R&S SMA product page at "Downloads" > "Manuals". - LAN Services secures controlled network access.
You can individually lock and unlock the supported LAN interface services, see "LAN Services".
Remote control via LAN interface requires that the interface is activated, but you can enable the required services specifically. - General security parameters as:
– USB Storage secures controlled access to the mass memory of the instrument. – Write nonvolatile memory protects against modification or deletion of data in the file system. – Annotation frequency and amplitude prevents reading the display. – User Interface prevents front panel operation and/or reading the display – Bluetooth enables operation of the instrument via Bluetooth.
![]() | Changing the password for the operating system or the security password requires that you enter the old password, the new password and that you confirm the new password. To assign the password, press the "Accept" button. This action can not be undone! Keep also in mind, that security settings are never reset, even if you perform a factory preset. |

Enables or disables the following interface services individually.
"SCPI over LAN" | activates access over LAN to remotely control the instrument using SCPI (Standard Commands for Programmable Instruments) commands. |
"VNC" | activates access via VNC (Virtual Network Computing) interface, a graphical desktop sharing system that uses RFB protocol to remotely control the instrument. |
"SSH" | activates access via SSH (Secure Shell), a network protocol for secure data communication. |
"HTTP" | activates access via HTTP (Hyper Text Transfer Protocol), the application protocol for hypermedia information systems. |
"FTP" | activates access via FTP (File Transfer Protocol), used to transfer files from a host to the instrument and vice versa. |
"SMB (Samba)" | activates access to SMB (Server Message Block), used for providing shared access to files, printers and serial ports of a network. |
"Avahi (Zeroconf)" | activates Avahi, a service for automatic configuration of the instrument in a network environment. |
"Software Update" | allows updating the instrument firmware via the LAN interface. For more information on this topic see the release notes of the instrument, provided on the Internet at the download site or the Rohde & Schwarz Signal Generator home page. |
Activates the access to external USB storage media.
This setting has no effect on a mouse or a keyboard, connected via USB.

Tip: Section "Enabling a locked user interface for manual operation" describes how you can unlock the control elements and the user interface.
"Enabled" | Enables the display and all controls for the manual operation of the instrument. |
"Display only" | Locks the manual operation of the instrument. The display on the screen remains and shows the current settings and changes. This security feature protects the instrument against unauthorized access, but still shows the current settings and processes, for example when you operate the instrument via remote control. The function disables:

- On the instrument's keypad or external keyboard, enter the security password 123456.
Even if you press any key, the instrument prompts you to enter the security password for unlocking.
Note The character of the first key you pressed is immediately added in the input field. Prior to inserting the password delete this entry. - In remote control mode, send the command SYST:ULOC ENABled to release all locks at once.
Alternatively, you can use the command SYST:KLOC OFF to unlock the keyboard, or SYST:DLOC OFF to release the display.
Via remote control, there is no password required.
