that can result in slight or minor injuries.

This tag indicates the possibility of incorrect use that can cause damage
to the product.

This tag indicates a situation where the user should pay special attention
to operating the product but which does not lead to damage.

Basic safety instructions

1. The product may be operated only under
the operating conditions and in the
positions specified by the manufacturer. Its
ventilation must not be obstructed during
operation. Unless otherwise specified, the
following requirements apply to
Rohde & Schwarz products:
prescribed operating position is always with
the housing floor facing down, IP protection
2X, pollution severity 2, overvoltage
category 2, use only in enclosed spaces,
max. operation altitude max. 2000 m.
Unless specified otherwise in the data
sheet, a tolerance of ±10% shall apply to
the nominal voltage and of ±5% to the
nominal frequency.

2. Applicable local or national safety
regulations and rules for the prevention of
accidents must be observed in all work
performed. The product may be opened
only by authorized, specially trained
personnel. Prior to performing any work on
the product or opening the product, the

product must be disconnected from the
supply network. Any adjustments,
replacements of parts, maintenance or
repair must be carried out only by technical
personnel authorized by Rohde & Schwarz.
Only original parts may be used for
replacing parts relevant to safety (e.g.
power switches, power transformers,
fuses). A safety test must always be
performed after parts relevant to safety
have been replaced (visual inspection, PE
conductor test, insulation resistance
measurement, leakage current
measurement, functional test).

3. As with all industrially manufactured goods,
the use of substances that induce an
allergic reaction (allergens, e.g. nickel)
such as aluminum cannot be generally
excluded. If you develop an allergic
reaction (such as a skin rash, frequent
sneezing, red eyes or respiratory
difficulties), consult a physician immediately
to determine the cause.

1171.0000.42-02.00 Sheet 2

Safety Instructions

4. If products/components are mechanically
and/or thermically processed in a manner
that goes beyond their intended use,
hazardous substances (heavy-metal dust
such as lead, beryllium, nickel) may be
released. For this reason, the product may
only be disassembled, e.g. for disposal
purposes, by specially trained personnel.
Improper disassembly may be hazardous to
your health. National waste disposal
regulations must be observed.

5. If handling the product yields hazardous
substances or fuels that must be disposed
of in a special way, e.g. coolants or engine
oils that must be replenished regularly, the
safety instructions of the manufacturer of
the hazardous substances or fuels and the
applicable regional waste disposal
regulations must be observed. Also
observe the relevant safety instructions in
the product documentation.

6. Depending on the function, certain products
such as RF radio equipment can produce
an elevated level of electromagnetic
radiation. Considering that unborn life
requires increased protection, pregnant
women should be protected by appropriate
measures. Persons with pacemakers may
also be endangered by electromagnetic
radiation. The employer is required to
assess workplaces where there is a special
risk of exposure to radiation and, if
necessary, take measures to avert the
danger.

7. Operating the products requires special
training and intense concentration. Make
certain that persons who use the products
are physically, mentally and emotionally fit
enough to handle operating the products;
otherwise injuries or material damage may
occur. It is the responsibility of the
employer to select suitable personnel for
operating the products.

8. Prior to switching on the product, it must be
ensured that the nominal voltage setting on
the product matches the nominal voltage of
the AC supply network. If a different voltage
is to be set, the power fuse of the product
may have to be changed accordingly.

9. In the case of products of safety class I with
movable power cord and connector,
operation is permitted only on sockets with
earthing contact and protective earth
connection.

10. Intentionally breaking the protective earth
connection either in the feed line or in the
product itself is not permitted. Doing so can
result in the danger of an electric shock
from the product. If extension cords or
connector strips are implemented, they
must be checked on a regular basis to
ensure that they are safe to use.

11. If the product has no power switch for
disconnection from the AC supply, the plug
of the connecting cable is regarded as the
disconnecting device. In such cases, it
must be ensured that the power plug is
easily reachable and accessible at all times
(length of connecting cable approx. 2 m).
Functional or electronic switches are not
suitable for providing disconnection from
the AC supply. If products without power
switches are integrated in racks or systems,
a disconnecting device must be provided at
the system level.

12. Never use the product if the power cable is
damaged. By taking appropriate safety
measures and carefully laying the power
cable, ensure that the cable cannot be
damaged and that no one can be hurt by
e.g. tripping over the cable or suffering an
electric shock.

13. The product may be operated only from
TN/TT supply networks fused with max.
16 A.

14. Do not insert the plug into sockets that are
dusty or dirty. Insert the plug firmly and all
the way into the socket. Otherwise this can
result in sparks, fire and/or injuries.

15. Do not overload any sockets, extension
cords or connector strips; doing so can
cause fire or electric shocks.

16. For measurements in circuits with voltages
V

> 30 V, suitable measures (e.g.

rms

appropriate measuring equipment, fusing,
current limiting, electrical separation,
insulation) should be taken to avoid any
hazards.

17. Ensure that the connections with
information technology equipment comply
with IEC 950/EN 60950.

18. Never remove the cover or part of the

AMIQ Introduction

Introduction

Task

Operating
principle

Transmission
error

AMIQ is a modulation source for complex baseband signals of state-of-the-art
telecommunication network s. 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 off ers two programs: WINIQ SIM
and AMIQ Control, a software for R&S vector signal generator SMIQ (see Section
"Software for AMIQ Control on page 1.8"). The desired inform ation 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 f ast and
accurate D/A converters. The outputs are (normally) connected to the modulation
inputs of an I/Q modulator (eg SMIQ), which m odulates the baseband signal onto the
desired RF (Fig. 1-1).

The RF signal is transmitted via the antenna to the receiver where it is converted
back into information data. On the transmission link, errors may be caused in the
information data stream by coding, impair ments and decoding. These errors can be
detected with the aid of option AMIQ-B1 (BER measurement) and evaluated.

AMIQ may be connected to a single-phase AC supply with a rated voltage from 100 V to 240 V and
rated frequency from 50 Hz to 60 Hz.

Note: AMIQ automatically sets itself to the local AC supply voltage. There is no need for

external switchover or exchanging fuses.

Use the power cord supplied with the AMIQ for
connection to the AC supply. Since the AMIQ is
designed in line with protection class I requirements

← AC supply connector
← Power fuses

to EN61010 it may only be connected to an earthing­contact type connector. As soon as the connection
has been established, AMIQ outputs a beep and the
ON LED lights with slightly reduced brightness. After
the start-up is completed, the ON LED is fully on.

Power Fuses

AMIQ is fully fused by two fuses IEC127-T4.0H /250 V. T he fuses are accommodated in the pull-out
fuse holder below the power connector. Before replac ing the fuses , disconnect the power cord from the
AMIQ. Use a screwdriver to lift the f use holder below the power connector and pull it out. Us e only fuses
of the above type.

Power Up / Switch-on Test

Ø Press switch-on key on the AMIQ front panel.

Note: No floppy should be in the drive when AMIQ is switched on. If

this happens nonetheless, one of the actions stored on the
floppy may be executed (see sections "New installation of
AMIQ software" and "Changing the IEC/IEEE-bus address in
this chapter).

Start-up procedure

Test of controller
hardware

After power-up the system is started, the c ontroller short test is perform ed
and the operating system DOS and the remote-c ontrol software are loaded
from the integrated hard disk. During this time the ON LED lights with
reduced intensity.

First the switch-on test for the integrated controller is perf ormed. Since at
this stage the LEDs are not driven, no inform ation can be obtained on the
device status. If a fault occurs, AMIQ outputs a sequence of beeps, the
meaning of which can be seen in the enclos ed main board manual. If a fault
occurs, the switch-on procedure is normally aborted.

AMIQ Putting into Operation

Short test of functional
hardware

Error messages

The AMIQ hardware is then set to operating state and tes ted. Any error is
signalled by two short successive beeps provided the built-in louds peaker
was not switched off with the IEC/IEEE-bus comm and :SYST:BEEP:STAT
OFF. At the end of the selftest a single beep is output. After this the
instrument is ready for operation.

Further information on er ror can be obtained by a repeated readout of the
error queue using IEC/IEEE-bus queries :SYST:ERR?.

Even if an error occurs, the s witch-on proc edure is in most cases continued
so that the error queue can be read out. The instrum ent may not be fully
functional however.

If an error is detected in the short test, the ON LED flashes.
With the short test completed successfully, the last active setup is

automatically loaded from the hard disk and the instrument is set to the
operating status before switch-off. The currently selected waveform is
loaded together with this complete setup. For a curve with 4.000.000
samples and with AMIQ 03, this may take up approx. 20 seconds. With
AMIQ 04 and its quadrupled mem or y capacity, the loading time increases to
approx. 80 s.

If no further errors oc curred, the ON and the CONTROL LEDs briefly light.
Afterwards, the ON and RUN LEDs come fully on.

If an error is detected the error message is entered in plain text into the
error queue of AMIQ and ON LED flashes. This is why after restart the
AMIQ control program in the host c omputer should read out the error queue
by means of the comm and SYST:ERR? until it is empty, i.e., until the entry
0,"No Error" is read. Depending on the error detected, AMIQ will
usually respond to commands tr ansmitted via IEEE-bus or RS-232 interface
but may not be fully functioning. The ON LED lights steadily at full
brightness.

Note

If ON LED flash fast, it is only a hint that AMIQ does not generate any c urv e
at the moment. It appears whenever a curve was stored directly to the
AMIQ’s SDRAM to save time before switching off AMIQ by means of the
MEM:DATA RAM, <binary block data> command (e.g. with
WinIQSIM via the settings Transmission, Force internal, Destination
AMIQ-RAM). This can be suppressed by loading curves via a waveform file
using the command MMEM:LOAD RAM, 'filename.WV'; such a curve is
available immediately after switching on the instrument.

Ø If AMIQ does not start as described above, check the AC supply

connection and, if required, replace the two power fuses (see section
"Power fuses" in this chapter).

Ø A complete self test of AMIQ’s hardware com ponents can be star ted with

the common command *TST?. Furthermore, the command
DIAG:SELF:SDRAM? can be used to test the whole SDRAM of AMIQ in
detail, see Sections „Common Commands“ and „DIAGnostic – Hardware
Diagnosis“ in Chapter 6.

Putting into Operation AMIQ

Instrument Switch-off

Ø Wait until the hard disk or the floppy disk drive are no longer accessed
Ø Remove floppy from the disk drive
Ø Press power switch on the front panel. All instrument settings are

retained.

EMC Shielding Measures

To avoid electromagnetic interference, the instr ument must always be closed when in operation. Use
only appropriate, shielded signalling lines and control cables. Particularly the line connec ted to the cloc k
output should be double-shielded and terminated.

AMIQ Connection to Test Setup

Connection to Test Setup

Connecting the Controller

AMIQ has no user interface of its own. An external controller is therefore required for operating AMIQ
which can be performed in two ways:

Connection via IEC/IEEE
bus

Connection via the serial
interface

Serial interface

AMIQ is simply connected to the IEC/IEEE bus. Upon delivery the bus
address is 6. If the bus address has been changed, e.g. by a previous
control comm and, or if the bus address has to be c hanged, proceed as
described in section "Changing the IEC/IEEE-bus address" on page 1.7.

AMIQ is connected to the serial interface of a PC by means of a null
modem cable. Connect the cable to the 9-contact sub-D connector of the
AMIQ labeled RS232. Use the COM1 or COM2 connector of the PC
which may be a 25-contact or 9-contact connector. Suitable adapters
may have to be used.

The serial interface is c onfigured for 9600 Baud, 8 data bits, no parity.
When the W inIQSIM software is used, which is recom mended by R&S,
the interface of the PC is automatically configured with the AMIQ
settings. However, the interface used has to be set in the menu first.

Pin assignment and wiring of the null modem cable are described in
section "Handshake" of chapter 5.

Changing the IEC/IEEE-bus Address

Upon delivery the instrument is set to address 6. If for any reason this address is not available, the
setting can be changed as follows:

Ø Generate a file on a PC, which contains only the following line:

:SYST:COMM:GPIB:ADDR x
with x being the desired address. Add an empty line.

Ø Copy this file under the name AUTOEXEC.IEC into the main memory of a 3.5" floppy.
Ø Insert the floppy in the AMIQ, switch AMIQ off and on again.
