Overview
In many cases it is imperative that R&S® SMU200A, R&S® SMATE200A, R&S® SMJ100A,
R&S® AMU200A or R&S® AFQ100A signal generator can be used in a secured environment.
Generally these highly secured environments will not allow any test equipment to leave the
area unless it can be proven that no user information will leave with the test equipment.
Security concerns can arise when signal generators need to leave a secured area to be
calibrated or serviced.
In the following the types of memory and their usage in the R&S® SMU200A, R&S®
SMATE200A, R&S® SMJ100A, R&S® AMU200A or R&S® AFQ100A signal generators is
described. It also addresses methods of ensuring that no user data will leave the secured area
if the product has to be removed for calibration or service needs.

In the following document, as instrument it is always referred to the R&S® SMU200A while the
information is valid for all models covered. If there are some special points for one specific
instrument, it is given and stated clearly.
Battery Information
The only battery used on the R&S® SMU200A is located on the CPU board. This battery is
used exclusively for powering the real-time clock in the chipset and the CMOS-SRAM memory.
The CMOS-SRAM memory is used only to store the BIOS setup.
The CMOS-SRAM is not a security concern.

Types of Memory in the R&S® SMU200A and its Security Concerns
SDRAM Memory
The R&S® SMU200A has 256/512 Mbyte of SDRAM memory on the CPU board. SDRAMs are
volatile memories and lose their data when the power supply is switched off. The SDRAM will
be unreadable within one minute after the power is removed from the instrument.
The SDRAM is not a security concern.
EEPROM Memory
Every module, with the exception of the motherboard, is equipped with a serial EEPROM.
These EEPROMs have a capacity of 2 Kbyte (memory size might be subject to changes
without further notice) and contain module-relevant data such as the serial number of the
module, calibration data, etc., and cannot be accessed by the user. The data can only be
changed by the service center when the R&S
cannot be stored on the EEPROM memory
®
SMU200A or the module is calibrated. User data
The EEPROM is not a security concern.
FLASH Memory
There are two FLASH memories in the R&S® SMU200A. The first 512k FLASH memory
contains the BIOS. It is on the CPU board of the R&S
The second 1 Mbyte FLASH memory contains module-relevant data such as the serial number
of the module, options, calibration data, etc. It is located on the motherboard of the R&S
SMU200A.
The user cannot access either memory. The FLASH memory data can only be changed by the
®
service center when the R&S
SMU200A or the module is calibrated.
The FLASH memory is not a security concern.
®
SMU200A.
®
Hard Drive
The hard drive is the nonvolatile storage medium in the R&S® SMU200, with the exception of
the R&S
Removable Hard Disc of the R&S®
Because the hard drive is nonvolatile, user data is not erased when power is removed from the
instrument.
®
AFQ100 instruments, which are eqiupped with a removable hard disc (see
AFQ100A).
The following information is stored on hard drive:
®
• The R&S
• The R&S
SMU200A 's operating system (Microsoft Windows® )
®
SMU200A's firmware
• Instruments states, setups and user data (e.g. waveforms)
The hard drive is a security concern.
