I/Q Modulation Generator
AMIQ is a modulation source for complex baseband signals of
telecommunication networks. Two synchronous outputs, which
are matched to each
other, and a large memory together with wide analog
bandwidth make AMIQ suitable
for universal use.
AMIQ has been designed to generate I and Q signals in the
baseband for present and
future types of modulation. "I" stands for the in-phase
component, "Q" for the
The data to be output by AMIQ are normally calculated by an
external workstation (eg
PC). To control this calculation, Rohde & Schwarz offers two

SMIQ (see Section
"Software for AMIQ Control on page 1.8"). The desired
information data stream (eg a
piece of speech) is generated and a modulation mode
selected. Then various
interference and distortions (so-called impairments) are
superimposed to this (ideal)
baseband signal. Thus a long sequence of sample values is
obtained, which are
loaded into AMIQ (via floppy, IEC/IEEE bus or RS-232
interface). The sequence in
the AMIQ memory is then output as analog I and Q signals
with the aid of fast and
accurate D/A converters. The outputs are (normally)
connected to the modulation
inputs of an I/Q modulator (eg SMIQ), which modulates the
baseband signal onto the
