Overview
In many cases it is imperative that R&S® SMU200A, R&S® SMATE200A, R&S® SMJ100A,
R&S® AMU200A, R&S® AFQ100A or R&S® AFQ100B signal generator can be used in a
ecured environment. Generally these highly secured environments will not allow any test
s
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, R&S® AFQ100A or R&S® AFQ100B 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.

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
