the unit into a 19" rack.
Chapter 2 explains the manual control of SMIQ. It contains fr ont and rear panel views,
describes the control elements as well as connectors, provides a short
introduction with sample settings for first-time users. It also explains how to
change parameters and the use of the list editor and gives an overview of the
menus for the func tions covered by the unit and its options. It also presents
the functions and menus of the unit and its options (frequency and level
setting, analog and digital modulation, ARB, external modulation source
AMIQ, fading simulation, noise generation and distortion simulation, BERT,
sweep, LIST mode, memory sequence and general functions not relating to
signal generation).

SMIQ Brief Instructions
3 Remote Control
The instrument is equipped with an IEC-bus interface accor ding to standard IEC 625.1/IEEE 488.2 and
a RS-232 interface. The connectors are located at the rear of the instrument and per mit to connect a
controller for remote control. T he instrument supports the SCPI version 1994.0 (Standard C
for Programm able Instruments) . The SCPI standard is based on standard IEEE 488.2 and aims at the
standardization of device-specific commands, error handling and the status registers.
This section assumes basic knowledge of IEC-bus programming and operation of the controller. A
description of the interface commands is to be obtained from the relevant manuals.
The requirements of the SCPI standard placed on comm and syntax, error handling and conf iguration of
the status registers are ex plained in detail in the respective sections. T ables provide a f ast overview of
the commands im plemented in the instrument and the bit assignm ent in the status regis ters . T he tables
are supplemented by a comprehensive des cription of every comm and and the s tatus register s. Detailed
program examples of the main functions are to be found in annex D. The program examples for
IEC-bus programming are all written in QuickBASIC.
Note: In contrast to manual control, which is intended for maximum possible operating c onvenience,
the priority of remote control is the predictability of the device status. This means that when
incompatible settings (e.g. activation of PM and FM at the same time) are attempted, the
command is ignored and the device status remains unchanged, i.e. is not adapted to other
settings. Therefore, IEC/IEEE-bus control progr ams s hould alway s define an initial dev ic e s tatus
(e.g. with command *RST) and then implement the required settings.

3.1 Brief Instructions
The short and simple operating sequence given below permits fast putting into operation of the
instrument and setting of its basic functions.
3.1.1 IEC-Bus
It is assumed that the IEC-bus address, which is factory-set to 28 has not yet been changed.
1. Connect instrument and controller using IEC-bus cable.
2. Write and start the following program on the controller:
CALL IBFIND("DEV1", generator%) Open port to the instrument
CALL IBPAD(generator%, 28) Inform controller about instrument address
CALL IBWRT(generator%, "*RST;*CLS") Reset instrument
CALL IBWRT(generator%, "FREQ 50MHz") Set frequency to 50 MHz
CALL IBWRT(generator%, "POW -7.3dBm") Set output level -7.3m dBm
"OUTP:STAT ON" Switch on RF output
CALL IBWRT(generator%, "AM:SOUR INT") Set AM modulation source LFGEN
CALL IBWRT(generator%, "AM:INT:FREQ 15kHz") Set modulation frequency to 15 kHz
CALL IBWRT(generator%, "AM 30PCT") Set AM modulation depth 30%
CALL IBWRT(generator%, "AM:STAT ON") Switch on AM
An amplitude-modulated signal is now applied at the output of the instrument.
3. To return to manual control, press the LOCAL key at the front panel.

Switchover to Remote Control SMIQ
3.1.2 RS-232 Interface
It is assumed that the configuration of the RS-232 interface at the unit has not yet been changed.
1. Connect unit and controller using the 0-modem cable.
2. Enter the following command at the controller to configure the controller interface:
mode com1: 9600, n, 8, 1
3. Create the following ASCII file:
Switch instrument to remote control (Return key)
*RST;*CLS
FREQ 50MHz
POW -7.3dBm
OUTP:STAT ON
AM:SOUR INT
AM:INT:FREQ 15kHz
AM 30PCT
AM:STAT ON
4. Transfer ASCII file to unit via RS-232 interface. Enter the following command at the controller:
copy <filename> com1:
Reset instrument
Set frequency 50 MHz
Set output level -7.3 dBm
Switch on RF output
Set AM modulation source LFGEN
Set modulation frequency 15 kHz
Set AM modulation depth 30%
Switch on AM
(Return key)
An amplitude-modulated signal is now applied at the output of the instrument.
5. To return to manual control, press the [LOCAL] key at the front panel.
3.2 Switchover to Remote Control
On power-on, the instrument is always in the manual operating state ("LOCAL" state) and can be
operated via the front panel.
The instrument is switched to remote control ("REMOTE" state)
IEC-bus as soon as it receives an addressed command from a controller.
RS-232 as soon as it receives either a car riage return <CR> ( =0Dh) or a line f eed <LF> ( 0Ah) f rom
a controller.
During remote control, operation via the f ront panel is disabled. The instrum ent remains in the remote
state until it is reset to the manual st ate via the front panel or via IEC bus (see Sections 3.2.1.3 and
3.2.2.3). Switching from manual operation to remote control and vice versa does not affect the
remaining instrument settings.
