3.2 Downgrade
Generally it is not recommended to use an earlier version than the latest version
available. In some cases the older versions do not support the hardware used in your
instrument. Before installing this firmware, check if this could happen:
►Start System ConfigSetupInstrument AssemblyVersions / Options
In the tab “Firmware”, you find the
►If the version to be installed is greater or equal than the “Min.Version”, the
hardware will be supported after downgrading. (However, this cannot be
guaranteed for all software options)
►If the version to be installed is lesser than the “Min.Version”, not all of the modules
will be supported. You instrument will not work after downgrading!
►Downgrading may fail using standard rsu-Files (eg. due to changes in the
instrument configuration file). In this case, press PRESET-Button during power-on
or install ISO image available from service department.
3.3 Update Information
The update procedure requires that the instrument is operational. There is no need to
uninstall the current firmware. Instrument settings are preserved during the update,
including user data and network settings.
To perform this procedure, USB Storage must be enabled in security settings.
Press the SETUP key, select Security and check USB Storage setting.

3.4 Updating the Firmware
Required equipment
Software:
Firmware update file SMBB_<version-number>.rsu
Hardware:
USB memory stick with enough free space to save the update file
(about 420 MByte).
The memory stick does not need to be bootable and previous data on the stick is not
affected. Several update files may reside on the stick in parallel. During update
procedure the stick is not modified by the instrument.
Prepare Memory Stick
Download update file to a PC
Connect USB stick to PC and copy the update file to the root directory
Wait until copy procedure has finished and remove USB stick
Install new firmware on R&S®SMB100B:
Connect USB stick to instrument
Switch on instrument, if instrument is powered off
Wait a few seconds until “Process Software Update?” message box appears.
Confirm by touching the YES Button or pressing the rotary knob.
Select firmware version using the arrow keys and press knob to start update
Wait until ”Software update successful“ message box appears. This may take
several minutes
Remove USB stick and touch the Reboot button
The instrument now reboots.
Execute internal adjustments (only if indicated)
Internal adjustments can be initiated manually (e.g. after warming up) by performing
the followings steps:
Press on the instrument front panel.
Press , select “Internal Adjustments…” and execute “Adjust All”.
This procedure updates all internal instrument adjustments and will take
several minutes.
Adjustments requiring external measurement equipment are not affected by the
firmware update and need not to be performed.
