I/Q Modulation Generator

Information

AMIQ is a modulation source for complex baseband signals of state-of-the-art 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 quadrature component. The data to be output by AMIQ are normally calculated by an external workstation (eg PC). To control this calculation, Rohde & Schwarz offers two programs: WINIQSIM and AMIQ Control, a Software for R&S vector signal Generator 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 desired RF

Information

Operating Manual The operating manual consisting of a data sheet and 10 chapters contains comprehensive informa- tion on characteristics, putting into operation, operation and remote control of AMIQ: The data sheet informs about guaranteed specifications and characteristics. Chapter 1 describes the operating principle of AMIQ, control elements and connectors on the front and rear panel as well as all procedures required for putting the instru- ment into operation and integration into a test system. Chapter 2 details instrument control via the remote interfaces with the aid of program ex- amples. Chapter 3 presents control and display elements. Chapter 4 describes key operating modes and special characteristics of AMIQ with refer- ence to possible applications. Chapter 5 describes programming of AMIQ, command processing, status reporting system and characteristics of hardware interfaces. Chapter 6 describes the remote-control commands defined for the instrument. At the end of the chapter an alphabetical list of commands is given. Chapter 7 contains program examples for a number of typical applications of AMIQ. Chapter 8 describes preventive maintenance. Chapter 9 gives hints on troubleshooting and contains a list of error messages. Chapter 10 contains an index for the operating manual
