1Information on the Current Version and
History
General information
This document describes the procedure to apply a firmware update to the
R&S®SMA100A Signal Generator. It furthermore describes the differences between the
several firmware versions. The most current firmware version can be obtained from
www.rohde-schwarz.com.
Instruments covered
This firmware version is suitable for all instruments of type R&S®SMA100A,
including all module revisions, options and firmware licenses.
Identify current firmware version
The current instrument firmware revision is displayed during the startup sequence of
the instrument. In addition, it is provided in the SETUP Software/Options dialog and it is
part of the SCPI *IDN instrument identification string.
Potential malfunction of assembly!
It is strongly recommended to do no firmware downgrade below the version the
device was originally delivered with. Improved module revisions as well as modified
structure of calibration data may not be supported by previous firmware versions.
1.1 Special hints for particular instruments and
firmware versions
Instruments with serial number 112000 or higher
It is not possible to downgrade the firmware to version less than 3.01.102.11. After a
downgrade the R&S® SMA100A does not work furthermore. The serial number of the
R&S® SMA100A could be obtained in the menu SETUP / Hardware Config .Please select
the entry SMA100A in the table Common Assembly.

R&S SMA100A Information on the Current Version and History
Release Notes for Firmware 1171.5360.52 5
Instruments with firmware greater or equal than 3.01.102.11
The R&S® SMA100A firmware does not support the folder /var/sma furthermore. The
folder will be deleted by the update process. All data stored in /var/sma will be moved
to /var/user. Please use the folder /var/user to save user data in the future.
Instruments with firmware greater or equal than 2.20.470.18
It is not possible to downgrade the firmware. After a downgrade an error message
“corrupt datablock found in Eeprom memory” appears.
Instruments with firmware less than 2.15.185.13
To update these instruments to the current firmware version, the update procedure
based on the ISO image file is required, as described in chapter 3.4.
Instruments with firmware less than 2.04.299.02
To update these instruments to the current firmware version, the update procedure
based on the ISO image file is required, as described in chapter 3.4.
Instruments with firmware prior to 2.05.68.13
Due to customer demands, starting with Firmware Version 2.05.68.13 the reference
oscillator settings are moved out of the scope of PRESET and *RST. This change
has been made since the reference oscillator loop takes several seconds to
synchronize and unintentional modification following *RST lead to long measurement
times and disturbance of other instruments relying on the reference.
In general the focus of *RST is to reset states regarding internal instrument operation
while leaving settings which are associated to the measurement and remote control
environment.
So in addition to the reference oscillator the following settings are out of the scope of
*RST:
RF Level Limit
Current level unit and EMF state
Remote control settings including GPIB address and emulation mode
Network settings
Keyboard and Screen Saver settings
Start / Stop GUI update
Power On settings
Security settings
With exception of the security settings these settings can easily be reset to factory
values by means of the function Factory Preset, located at the bottom of the SETUP
Menu. Factory Preset includes the scope of PRESET. Security settings (e.g. passwords
and enable/disable states of USB and LAN) are not affected to maintain instrument
security. For remote operation the command SYST:FPReset is provided. Be aware
that executing this command likely terminates the remote connection.

Furthermore, beginning with Version 2.05.68.13 the behavior of the key WINBAR has
changed. It now directly toggles between the open setting dialogs. It is not necessary
to use the rotary knob.

Release Notes for Firmware 1171.5360.52 18
●New feature remote control emulation HP 8664/8665
Modified Functionality
●ILS-GS and ILS-LOC: New parameter DDM Polarity. In the default state this value
is 90 Hz – 150 Hz
●All avionics modulation (Options R&S® SMA-K25 and R&S® SMA-K26):
Enhanced COM/ID settings, with the possibility to set individual dot, dash, symbol
space and letter space length.
●NRP-Z Power Viewer: Support of up to three R&S NRP-Zxx power sensors. The
different R&S NRP-Zxx power sensors can be selected via a combobox at the top
of the dialog NRP-Z Power Viewer.
●The summary screen (large frequency and level display) can be activated and
deactivated in the menu Setup → Display Settings. In the default state the
summary screen is deactivated. This setting is not affected by pressing the
PRESET button or sending *RST.
●The RF output can be deactivated, if the reference oscillator source is set to
external and no reference signal is connected. In this case the RF output can be
deactivate in the menu RF → Ref Oscillator. In the default state the RF output is
not deactivated. This setting is not affected by pressing the PRESET button or
sending *RST.
Fixed Issues
●LF Output: The LF generator frequency differs for more than 5 mHz
●Dialog of the online help window too large
●Adjustment: If the internal adjustments are executed with external reference, and
no external reference is connected, no error message occurs. Phase continuous
frequency settings: In rare cases the frequency synthesis could be work in an
undefined state. Only with R&S SMA-B20
●ILS-GS and ILS-LOC: Improvements for DMM input in µA
●Remote control emulation: No remote sign in emulation mode
●Remote control emulation Aeroflex 203x/4x: The command MODE does not work
1.21 Version 2.05.68.18
Released: July 2008
Fixed Issues
●External Pulse Modulation: Unwanted double pulse at rising pulse edge
