Resolving Security Issues
When Working with the R&S®ESIB in
Secure Areas
Based upon the user’s security requirements, this document describes the Rohde&Schwarz options
available to address the user’s EMI test receiver needs. It also covers the different memory types and
locations where user information can be stored in the EMI test receiver R&S
For secure environments, it describes an approach to physically remove the user data from the
EMI test receiver.

In many cases it is imperative that the R&S®ESIB EMI test receiver 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 EMI test receivers need to leave a
secured area to be calibrated or serviced.
This document describes the types of memory and their usage in the R&S
ESIB EMI test receiver. It also addresses methods of ensuring that no user
data will leave the secured area should the product be removed for
calibration or service needs.

3 Battery Information
There are no batteries in the R&S®ESIB EMI test receiver other than the
one on the CPU board used to buffer the SRAM and to power the clock in
the chipset.

4 Types of Memory in the R&S®ESIB EMI Test Receiver and Their
Security Concerns
SDRAM
The R&S®ESIB EMI Test receiver has 64 MByte of SDRAM on the CPU
board.
In addition there are four RISC processor units (Transputer) in the R&S
ESIB. The Transputers are each equipped with memory: 3 x 1MByte and 1
x 4MByte SDRAM memory.
SDRAM is volatile memory and it loses its memory as soon as power is
removed. The SDRAM will be unreadable within one minute after the power
is removed from the instrument.
The SDRAM is not a security concern.
EEPROM
Each board assembly in the R&S®ESIB EMI Test receiver has one serial
EEPROM device. These devices hold 256 Byte up to 2 kByte and contain
information related to the installed hardware, such as board serial number,
options, correction constants, etc. This data can be changed only by the
factory or by service personnel when performing adjustments. The
EEPROM does not hold user data nor can the user access the EEPROM
storage.
®
The EEPROM is not a security concern.
FLASH EPROM
The CPU board of the R&S®ESIB EMI Test receiver has one 512 kByte
flash EPROM memory device which contains the BIOS. The Flash memory
does not hold user data nor can the user access the Flash memory.
The Flash EPROM memory is not a security concern.
