1 Overview
1 Overview
This application note presents possibilities for including the R&S Test and
Measurement Instruments into the Agilent ADS Design System.
The Agilent ADS Design System is a powerful electronic design automation software
system. It offers complete design integration to designers of products such as cellular
phones, wireless networks, and radar or satellite communications systems. Both
analog and digital simulation can be combined, leading to a complete simulation
solution from the bit source up to the output RF power of a complete transmitter
system and also back again into the receiver for all known digital communication
standards.
By using real-world instruments in combination with such a design system, the design
flow can be much more efficient, for example
generate the baseband signal for a new digital communication standard and feed
this signals from ADS into a real-world ARB and RF signal generator to create this
signal and examine e.g. an RF amplifier
check the influence of digital filters, coding, … on the real world signal
record a real-world signal from e.g. an transmitter and check the parameters in
comparison to the original signal - also in the presence of a simulated signal with
noise, fading, …
integrate the parameters of a real-world Device Under Test (S-parameters of an
amplifier, …) into your design by using a Vector Network Analyzer for
characterization
These are only a few ideas how about integrating test equipment into your design flow.
With this application note, ways for integrating Rohde & Schwarz test equipment into
ADS will be preset. This integration will be available for both analog and digital
simulations, and signal sources as well as signal sinks can be included into your
design.
The main key features of this solution are:
One-button-solution (as easy to operate as the ADS simulator).
Components for analog and digital simulation.
Direct integration into ADS (including R&S specific palettes, menus, schematic
symbols).
Complete instrument configuration within the ADS Design Environment.
Multiple Instrument Components (1 component support all instruments for the
desired measurement task)
Automatic generation of files in well-known ADS formats (TIM, SIG, S2P, …) during
the simulation.
Support of all interfaces to the instruments (IEEE, LAN, …) for all integrated
components.
Protocol and log file generation for all operations.

1) As SMU, SMJ, SMATE and SMBV are fully compatible for IQ modulation, SMJ, SMATE and
SMBV are referred to as SMU in general in the following descriptions.
To understand the description and the basic principle of operation, some words on the
basic design. The provided solution consists of 2 parts:
1. The RS ADS Interface (RSADSIF) which is an executable installed on your local
PC. It provides the link to the RS Instruments via various bus systems (IEEE, LAN,
…) and takes care on the data transfer. Instrument scanning, operation logging
and data format conversion are done within this software.
2. The RS ADS Design Kit (RSADSDK) which is installed as Design Kit within ADS.
This Design Kit provides the components for RS instruments within the ADS
schematic, generates the menu items in the Schematic Window and realizes the
export of instruments settings to the RS ADS Interface.
To use the Rohde & Schwarz ADS Integration, both components are required to be
installed.

1)
RunPreSim and RunPostSim determine if the communication with the instrument shall be done
before and/or after the simulation of the circuit.
If you do not want the simulator to control the component, select NO for both values.
2)
If RunPreset is selected, the command "SYST:PRES" (equivalent to pressing the PRESET key at
the front panel) will be executed before other settings are performed on the instrument.

3)
If RunRFSetup is selected, the settings for RFFrequency, RFLevel, RFRefOscSource and RFOn will
be executed.
4)
The data from the instrument are always stored as SIG files with the name "FSx_IQ_IN_I.SIG" and
"FSx_IQ_IN_Q.SIG" in the "\data" directory of the current project.
If you want additional copies of the file in the SIG or TIM format, you can specify LocalFileName and
LocalFileType for name and type.
The complete filenames will be <LocalFileName>_[I/Q].[SIG/TIM].
5)
IQSampleClock and IQSampleLength must be entered according to the valid value range as
described in the table above.
6)
IQPreTriggerSamples specified the number of samples between the trigger event and the start of the
IQ data recording itself.
7)
If IQScaleMode is set to VOLT, IQ input samples are assumed to be voltage values. An overrange of
the values will result in an error.
If MAX is selected, IQ input samples will be scaled to fit the value range of the D/A converter with
maximum dynamic range.
8)
IQAvgOn and IQAvgCount switches the averaging of IQ samples within the FSU on or off.
If averaging is selected, IQ data are averaged inside the instrument with phase synchronized
sampling according to the external trigger.
9)
If an FSQ with option FSQ-B71 is used, IQSource can be switched between RF and Baseband (BB)
source. For baseband inputs, additional options (IQBBDither , IQBBLowPass , IQBBBalanced and
IQBBImp) are available.
10)
The TriggerMode can be switched between Immediate (IMM), External (EXT - Trigger provided by
the backpanel BNC connector), IF Power (IFP - Standard Bandwidth Detector) and RF Power (RFP Bandwidth Extended Detector for FSP).
Use TriggerLevel to set the level for IF and RF Power Trigger level.

9.1 ARB_IQ_Sink
Symbol and Description
The ARB_IQ_Sink model downloads time domain IQ data from ADS to the R&S Vector
Signal Generator or Arbitrary Waveform Generator or R&S I/Q Modulation Generator.
The simulated IQ data are stored from ADS to the local PC disc and then automatically
transferred to the ARB generator by calling the RS ADS Interface.
The files which are downloaded to the ARB are called "ARB_IQ_Sink_I.SIG" and
"ARB_IQ_Sink_Q.SIG" and are stored in the "\data" directory of your simulation.
Note: Please make sure that your ADS design delivers an equal number of I and Q
data by adjusting the START and STOP parameters of the simulation (e.g. DefaultTimeStart/Stop and DefaultNumericStart/Stop). If the number is not equal a warning is
displayed in the R&S simulation window and the smaller number is used.

Frequently Asked Questions
Question
I can not find my instrument connected via the network interface.
Answer
Please start the RS ADS Interface, use the VISA Resource Editor and add a Network instrument
connection by using the "Add" button.
Question
When I start my digital simulation with the ARB sink, the error message: "There are no sources or
sinks that control the simulation" occurs.
Answer
The ARB_IQ_Sink component is set to "ControlSimulation = NO" by default. It will collect as many
data as are available.
Please insert a source that has the attribute "ControlSimulation = YES".
As a workaround (if you do not have any other elements controlling the simulation), add a
"NumericSink" control that controls the simulation:
If this is not possible in your design, please push into the ARB_IQ_Sink (select the button below
and click the ARB_IQ_Sink component) and set both TimedDataWrite elements to
"ControlSimulation = YES".
Details on the Control of the Simulation can be found in the ADS Manual "ADS Ptolemy
Simulation", Chapter 3, Paragraph "Sources and Sinks Control the Simulation".
Note that these settings will NOT be stored when leaving the design.
Question
When I run a simulation based on an S4P model I get the error “Not all S-parameters on one
channel”.
Answer
Please make sure that all S-Parameters that are to be measured are on one channel. An easy way
is to use the “All S-Params” soft key on the instrument.
Question
When I open a design containing R&S instruments, I get error messages and the symbols of the
instruments are missing
