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)
