Brief description

The SME supplies the complex signals
required for the development and test-
ing of digital mobile radio receivers. It
is capable of generating all signals
used in the main digital radio net-
works in line with relevant standards
regarding the type of modulation,
data format, TDMA structure and fre-
quency hop patterns. The SME is com-
pletely at home also in the analog sig-
nal world of conventional signal gen-
erators.

SME02, SME03 and SME06 are
identical except for the frequency
range. Economy Signal Generator
SME03E has been designed as an
especially economical solution for
applications involving digitally modu-
lated signals. The large variety of
options available allows the SME to
be tailored to the specific needs of the
user.

Main features

• All common digital modulation

modes provided in one unit

• Great ease of operation thanks to a

novel menu concept

• No external modulation and data

sources required

• User-programmable data

sequences and TDMA structure

• RF, LF and level sweep
• Ultra-low RF leakage for measure-

ments on highly sensitive pagers

• List mode: programmable measure-

ment sequence for up to 4096 fre-
quency and level combinations, set-
ting time <0.5 ms (not SME03E)
