This manual applies to instruments with software issues of 2.0 and higher.
This manual explains how to set up and configure an Aeroflex 3020 digital RF signal
generator PXI module. Where necessary, it refers you to the appropriate installation
documents that are supplied with the module.
This manual provides information about how to configure the module as a stand-alone device.
However, one of the advantages of Aeroflex 3000 Series PXI modules is their ability to form
versatile test instruments, when used with other such modules and running 3000 Series
application software.
Getting Started with afSigGen (supplied on the CD-ROM that accompanies each module (see
Associated documentation)) explains how to set up and configure a 3020 Series digital RF
signal generator with a 3010 Series RF synthesizer module. Using the signal generator soft
front panel and/or dll or COM object supplied, the modules form an instrument that provides
the functionality and performance of an integrated, highly-specified signal generator, but with
the adaptability to satisfy a diverse range of test or measurement requirements.

Preface
The PXI concept
VXI and GPIB systems meet the specific needs of instrumentation users but are often too
large and expensive for mainstream applications. PC-based instrumentation may cost less but
cannot meet the environmental and operational requirements of many systems.
PXI (PCI Extensions for Instrumentation) is based on CompactPCI, itself based on the PCI
standard. PCI was designed for desktop machines but CompactPCI was designed for
industrial applications, and features a rugged Eurocard format with easy insertion and
removal. PXI adds to the CompactPCI specification by defining system-level specifications
for timing, synchronization, cooling, environmental testing, and software. While PXI extends
CompactPCI, it also maintains complete interoperability so that you can use any CompactPCIcompliant product in a PXI system and vice versa. PXI also makes use of Windows software,
VXI timing and triggering, and VXIplug&play instrument drivers to provide powerful and
affordable systems.

Chapter 1 GENERAL INFORMATION
Introduction
Welcome to the operating manual for the 3020 digital RF signal generator PXI module.
The 3020 is an RF signal generator output module that provides a frequency range of
250 MHz to 2.5 GHz and a level range of +5 dBm −120 dBm. Modulation can be digital or
vector, and the module contains an IQ baseband arbitrary waveform generator. An external
local oscillator provides an LO signal: the 3010 Series RF synthesizer is recommended, where
the two modules together form a digital RF signal generator that occupies only three slots in a
3U PXI chassis.
1-1
GENERAL INFORMATION
Applications
The 3020’s performance makes it ideal for generating complex modulated waveforms for
digital radio communications test applications. When used with other Aeroflex PXI RF
modules, complete RF test systems can be designed.
Wide frequency coverage
The 3020 produces IQ-modulated or CW signals between 250 MHz and 2.5 GHz with an IQ
bandwidth of up to 14 MHz. A low noise frequency agile LO input can be provided by the
3010 Series RF synthesizer module. The 3020 is ideal for multi-purpose applications in radio
communications, especially important when testing multi-mode cellular terminals.
Low noise and frequency-agile
When used with a 3010 Series synthesizer, the 3020 provides the low noise floor and speed
necessary to provide high-productivity RFIC testing or the stimulus to frequency-hopping
radios.
RF bursting
As well as maintaining accurate RF output levels, the 3020 can generate modulated RF bursts
to simulate TDMA signal characteristics.
Arbitrary waveform generator (ARB)
The ARB can store 32 MSamples, either as a single long waveform or any number of smaller
waveforms up to the capacity limit of the sample memory. Waveforms transfer quickly
between the PXI controller and the ARB because of the wide bandwidth of the PCI backplane.
IQ vector modulation
The 3020 provides high-quality vector modulation either from the internal ARB or from an
external source via the LVDS data connector.
1-2
GENERAL INFORMATION
Triggering
The 3020 provides versatile triggering facilities to provide flexibility when used with other
instruments. Trigger inputs can be routed directly through the LVDS front panel input or
across the PXI backplane. Triggers can generate power bursts and can be programmed into
waveforms to provide trigger outputs for other instruments.
Signal routing
A configurable routing matrix provides flexibility in how you interconnect signals on the PXI
backplane, the LVDS front-panel input and the module’s internal functions. Predefined
routing scenarios can be loaded, or new scenarios created to meet particular requirements.
Software
The 3020 is supplied with a VXI PNP driver and soft front panel for use as a self-contained
module. An instrument-level signal generator soft front panel, dll and COM object are also
supplied, which allow you to use the 3020 together with a 3010 or 3011 RF Synthesizer.
Refer to Getting Started with afSigGen (part no. 46892/678) supplied on the PXI Modules
CD-ROM part no. 46886/028.
® allows you to design your own, or system-specific, complex modulation files for
use with the 3020’s ARB.
RF Investigator, also supplied with the module, is an application that provides combined
operation of all Aeroflex 3000 Series modules from a single user interface, especially useful
for acceptance testing.
PXI Studio, also supplied with the module, configures your PXI modules as logical
instruments that will eventually run analysis plugins to suit any modulation scheme.

OPERATION
Soft front panel (af3020_sfp)
The soft front panel provides a graphical interface for operating the module. It is intended for
testing and diagnosing, for demonstration and training, and for basic operation of the module.
It represents most of the functions available in the instrument driver. It is not however a
comprehensive application suitable for measurements; for this, use the afSigGen DLL or
afcomSigGen COM object.
Installation
The soft front panel is installed during the driver installation process (refer to the 3000 Series
PXI Modules Common Installation Guide, part no. 46882/663).
Open the AF3020_sfp.exe file: this is in the C:\VXIPNP|WinNT\af3020\ directory on a
Windows NT machine, for example. It is also accessible from the Windows Start menu under
Programs\Aeroflex\PXI Module Front Panels\AF3020 Front Panel. The soft front panel,
similar to that in Fig. 3-2, is displayed.
Detailed help information
Soft front panel controls are all available as driver export functions unless noted otherwise,
and are documented in the help files (page 3-25). This operating manual provides an
overview of the facilities that the module provides and summarizes its operation; however,
refer to the help files for detailed descriptions of functions together with their parameter lists
and return values.

Load and Save allow you to load and save soft front panel configurations from and to your
preferred locations. If you did not change the default location when installing the software, it
is C:\VXIPNP\WinNT\af3020\settings, and configurations are saved as .ini files.
You can edit, copy and paste settings files as required; for example, you may want to
save only a new routing setup without changing other parameters. Edit the saved .ini
file using a text editor (for example, Notepad) to remove unwanted parameters. Ensure
only that you do not delete the General (VendorID, DeviceID) and Version
(Major/Minor) parameters. Save the changed file. When the settings file is next loaded,
the configuration of the soft front panel changes to match the parameters remaining in
the settings file, leaving all other settings unchanged.
Directories lets you choose the locations for your front-panel configuration settings, ARB
files and catalogs, synthesizer plugin DLLs and calibration files.
Synthesizer plugins must support a VXIPNP (VISA) RF synthesizer resource capable of
1.5 GHz to 3 GHz. Certain exported functions are also required: refer to online help for
details.

IQ Bandwidth Correction. Normally off. On Manual, provides up to 3 dB compensation to
correct for roll-off on the internal analog IQ path. The maximum correction of 3 dB provides
a nominally flat response across 14 MHz. The maximum available power from the module is
reduced by the correction figure selected.
Routing Scenarios allows you to select a predefined routing matrix connection. A tick
against the scenario’s title shows that it is selected.
If you select a scenario, and then a second, any connected or enabled outputs common to both
scenarios are overwritten by the second. Enabled outputs in the first scenario that do not
appear in the second also remain active. If the second scenario changes any outputs that were
used by the first, the first scenario is invalidated. This process extends to further scenarios.

User Cal
Calibration is needed to ensure that some specifications — such as carrier leak — are met, and
are guaranteed only if a user calibration has been performed. The module calibrates at the
current frequency, or at a range of frequencies, and stores the results so that if you change
frequency and return again, the calibration still applies.
In some cases, an LO signal is required; the user calibration screen prompts for the
LO Plugin Filename. You can browse for this and boot the selected device from the User
Calibration screen.
IQ Calibration
Cal Current Frequency calibrates the IQ modulator at the current frequency.
Calibration is valid for frequencies within ±1 MHz of the current frequency. The plugin
is not used, but the LO signal must be present at the correct frequency.
Cal All Bands calibrates the IQ modulator over the entire frequency range of the
module and returns the instrument to its current state. The plugin is required.
Cal Selected Band calibrates the IQ modulator over individual bands and returns the
instrument to its current state. The plugin is required.
Store Single Point/Banded to File lets you save calibrations using the standard
Windows browser. Calibrations are saved as .ciq files.
Restore Single Point/Banded from File lets you restore .ciq calibrations using the
standard Windows browser.
Detector Zero
Zero sets the levelling detector to zero. This ensures that the module meets the level
accuracy specified in the data sheet. No LO plugin or LO signal is needed.

Gate RF
Determines whether RF output is turned off below a predetermined level. If set to 1

This minimizes IQ leakage to a nominal –80 dBc during periods when the signal is ‘off’.
Attenuator Hold
As the step attenuator changes range, small changes in VSWR can occur. Check the box to
freeze the attenuator on its current range.
The maximum positive excursion is restricted to the 8 dB range of the attenuator pad, but you
can reduce the RF level over a range of up to 40 dB. However, the level accuracy
specification is invalid if you exceed the pad’s range by more than a few dB.
With attenuator hold disabled, the RF level hardware is set for optimum level accuracy and
spectral purity, and changes to the attenuator setting are possible.
Note that level accuracy and spectral purity cannot be guaranteed outside the normal level
range.
The current active RF channel cannot be changed while attenuator hold is on.
Levelling Mode
Auto (RMS/Pk) sets leveling automatically to RMS for ARB files that contain appropriate
header information (most

Frozen freezes leveling at the current settings.
Peak causes the set RF Level to appear at the RF output if you apply maximum full-scale I
and Q sample values. As I and Q are decreased, the output decreases proportionally.
RMS causes the set RF Level to appear at the RF output if the RMS value of the applied IQ
data stream equals the value set in the RMS (dBc) field. When you select this leveling mode,

Format of ARB files
General
The ARB stores digital representations of waveforms. Any number of waveforms can be
stored, up to a total capacity of 32 Msamples. The memory used is volatile.
Each waveform consists of two components, I and Q. When the ARB is enabled and one of
the waveforms selected, it is converted into a pair of analog signals that can be used to drive
the I and Q channels of the RF modulator. Waveform data files are created externally and
require packaging before they can be used by the ARB.
Each sample contains two 14-bit numbers, one each for I and Q. To minimize the required
file size and reduce aliasing problems, the ARB includes an interpolator to increase the D-A
converter sample rate by factors of between 2 and 3072 so that the D-A converter runs at
between 44 and 66 M sample/s.
A waveform is looped continuously. The rate at which the sample plays is set during file
creation.
An example showing data rates and sizes for an
IS-95 waveform
IS-95 has a chip rate of 1.2288 Mchip/s. For our purposes we will consider a chip to be the
significant symbol. Each symbol must be sampled at least four times. This would give a rate
of 4.9152 Msample/s. There are 24 576 symbols per 20 ms frame. Four frames would have
98 304 symbols, which after oversampling gives 393 216 samples. As the oversample ratio
increases, the file becomes larger.
When the above waveform is selected and played, it is read out of the memory at
4.9152 Msample/s. The ARB interpolates this data stream so that it has a data rate of
58.9824 Msample/s.
A-1
FORMAT OF ARB FILES
The data is written to the two 14-bit D-A converters at 58.9824 Msample/s. The analog
outputs from the D-A converters are then filtered to remove switching and quantization noise
and high-frequency images. The I and Q outputs are then routed to the RF modulator.
Markers
Markers are used to mark important events within the file; for example, the start of a TDMA
slot or frame.

DATA connector and timing
The DATA connector is a 68-way female SCSI-type LVDS (low-voltage differential
signaling) interface. It can be used to input data and associated control and timing signals.
The DATA connector is shown in Fig. B-1. Signals are transmitted using LVDS to
ANSI/TIA/EIA-644.

C5504
The DATA interface provides:
• input for IQ data
• input/output for trigger and marker signals.
The electrical level is LVDS: VOH typically 1.38 V, VOL typically 1.03 V
Data is supplied to the LVDS interface using a 16-bit bus. The D/A converters are 14 bits and
by default the 3020 uses bits [15:2]; however, it is possible to select to use [13:0] instead.
Similarly, data is signed two’s complement by default, but it is possible to select unsigned
instead. See LVDS (page 3-4).
IQ data pairs are clocked sequentially, with I always followed by Q. I data is clocked into the
3020 on the first CLK_IN edge following IQSELECT_IN going high. Q data is clocked in on
the first edge following IQSELECT_IN going low.
Multiple CLK_IN cycles can occur between IQSELECT_IN changing state, and CLK_IN can
be any frequency up to 132 MHz. However, the resulting IQ sample pair rate must be the
same as the sample rate set for the instrument. For this to occur, it is important to lock
CLK_IN to the same 10 MHz reference that the instrument is using, otherwise frequency drift
will cause periodic data errors.

Chapter 4 BRIEF TECHNICAL DESCRIPTION
Introduction
The 3020 is a Digital RF Signal Generator PXI module. It contains dividers to give a
frequency range of 250 MHz to 2.5 GHz, IQ modulators, leveling control, step attenuation to
−120 dBm, and an IQ baseband arbitrary waveform generator. It does not contain a local
oscillator, relying instead on a 3010 RF Synthesizer to provide an LO signal. The two
modules together then form a digital RF signal generator.
The 3020 comprises two printed circuit boards, both aligned with the PXI card slots. The
logic and control board contains the PCI interface, baseband VCO, IQ ARB, leveling control
and an external LVDS data interface. The RF board is housed in a full clamshell shield,
containing RF dividers, IQ modulators, output amplifier and step attenuator.
Only the logic board connects to the PXI backplane, so power and control to the RF board is
routed through the logic board. A single 40-way ribbon cable connects the boards, handling
power to the RF board, differential analog IQ, analog leveling signals and various switched
control signals.
A block schematic for the instrument is shown in Fig. 4-1.
Logic and control board
The PCI interface uses an FPGA, which boots up at power-on from a local ISP PROM. The
interface provides all the required PCI-compliant handshaking and data transfer. A serial
EEPROM is used for calibration data as well as all module information, such as serial
number.
A baseband VCO generates a clock signal for the IQ generation and processing. This is a
fractional-N-based system, operating from 88 to 132 MHz and using either the PXI 10 MHz
clock or an external 10 MHz signal as its reference.
4-1
BRIEF TECHNICAL DESCRIPTION
Analog IQ signals are generated by two DACs, their clocks supplied directly from the VCO at
88–132 MHz. The DACs interpolate at 2x, giving a data rate of 44–66 MHz. The DACs each
produce differential signals that are fed through filters, two for each DAC. The data for the
DACs has three possible sources: static registers for CW operation, the internal ARB, or the
LVDS data interface.
The ARB consists of SDRAM devices configured as 64-bit-wide memory. An SDRAM
controller handles bursted writing and reading from the memory. The ARB sample width is
32-bit: 14-bit I, 14-bit Q, and 4-bit markers. The memory is configured as 64-bit to provide
capacity to set up bursts and perform the frequent auto-refreshes required of SDRAM.
The LVDS interface provides a digital input. A rate-matching FIFO is used to allow the data
source to use an independent clock, but it must be assumed that it is locked to the same
reference for correct operation.
Digital interpolation filters allow a range of data rates less than the 44 to 66 MHz clock range.
The highest order of interpolation is 3072, which means the lowest sample rate is 14.323 kHz.
These filters are used on both ARB and LVDS data. The 3020 applies all corrections to IQ
data in the digital domain. This includes DC offset, gain imbalance and phase skew between I
and Q. Additional digital filters are used to correct for inaccuracy in the analog reconstruction
filters and frequency response of the DACs.
A closed-loop leveling control drives leveling on the RF board via a 14-bit DAC. The signal
from an RF detector after this stage is converted by an ADC.
The leveling loop derives its error signal by comparing the input to the comparator from the
RF detector ADC, and the wanted IQ power. The IQ power is converted to detector volts in a
look-up table. During bursted IQ data, the loop can be frozen while ramping IQ data up or
down, and can also switch off the signal between bursts, improving on-off ratio.
A burst of data from the detector ADC can be stored and retrieved by the software driver,
which is useful for operations such as offset-nulling the ADC and performing IQ calibration.
During IQ calibration short test-signals are loaded to the ARB, and by synchronizing ADC
data capture, the driver can make the necessary calculations and corrections to IQ offsets, gain
and skew.
4-2
BRIEF TECHNICAL DESCRIPTION
RF board
LO input and RF output is via front-panel-mounted SMA connectors. The LO input is in the
range 1.5 to 3 GHz at a nominal level of 0 dBm. Frequency division extends the available RF
output frequency range down to 250 MHz. The RF signal is generated using an IQ modulator,
which accepts divided LO and IQ baseband signals.
The LO input signal drives a chain of three dividers. A signal at the required output frequency
is routed from the appropriate divider to one of two IQ modulators via harmonic filtering.
One modulator covers frequencies from 250 MHz to 1 GHz; the other, frequencies from
1 GHz to 2.5 GHz. Filtering is repeated after the modulators. The appropriate signal is routed
to the output section.
A PIN attenuator operates over a range of at least 20 dB. The drive to this level control
incorporates a shaping network to approximate to logarithmic control. The leveling is entirely
under software control and as such is completely flexible.
Level detection takes the form of voltage sensing behind a 50 ohm resistor.
The switchable step attenuator operates in increments of 8 dB, from 2 dB up to 130 dB. The
attenuator uses 50 ohm resistive pads that are switched in and out of circuit. The incremental
attenuation values are 32, 8, 32, 16 and 32 dB.
The detector output is amplified and buffered before being fed back to the logic board for A-D
conversion. A temperature-sensing mode is provided, where the detector is disabled and the
output replicates the voltage. This can be measured and used to periodically adjust calibration
in accordance with temperature and stored data.

Chapter 5 ACCEPTANCE TESTING
Introduction
The test procedures in this chapter enable you to verify that the 3020 digital RF signal
generator is meeting its specified performance.
Abbreviations
Throughout the chapter, the following abbreviations are used:
UUT Unit Under Test
SFP Soft Front Panel
Test procedures
Each test procedure shows you how to configure the test equipment and then describes how to
perform the test. Tables are provided for recording your results. Measurements should fall
within the maximum and minimum limits indicated, provided that you use the recommended
test equipment and adhere to the test precautions.
The tests recommend the use of conventional ‘rack and stack’ test equipment, apart from the
LO for the 3020 UUT, where an Aeroflex 3011 RF synthesizer is recommended, although a
conventional signal generator may be used. Other PXI modules may be used as long as they
comply with the minimum specification.
Controlling the UUT
If a separate ‘rack and stack’ signal generator is being used as an LO for the 3020, then
control of the UUT is via the af3020 SFP. A column in the results tables advises the required
LO frequency for the signal generator.
5−1
ACCEPTANCE TESTING
If a 3011 PXI RF synthesizer is being used as an LO for the 3020, then control of the 3011
and 3020 is greatly simplified by using the SigGen SFP. This controls both modules together
so that the LO is set automatically to the required frequency.
Note: these test procedures are written assuming that you use the SigGen SFP. They may
differ slightly if you use the af3020 SFP.
Both SFPs are on the supplied CD−ROM (part no. 46886/028) as part of the common
installation.
Follow the instructions provided in the 3000 Series Common Installation Guide (part no.
46882/663) to ensure that this software is correctly installed.
Each test procedure relies on the module being set to its power−up conditions. To avoid
switching the instrument off and back on, reboot the module via the SFP as follows:
af3020 SFP:
• Click on Boot.
• Select the appropriate resource from the list.
• Click on OK.
• After a few seconds, the indicator turns green to show that the boot sequence has
completed successfully.
SigGen SFP:
• Click on Boot.
• Select the appropriate AF3020: resource from the list.
• Select the appropriate LO synth: resource from the list.
• Click on Boot Instrument.
• After a few seconds, the indicator turns green to show that the boot sequence has
completed successfully.
Note that for clarity, the PXI chassis and controller are not shown in the test equipment
set−up diagrams.

Test precautions
To ensure minimum errors and uncertainties when making measurements, it is important to
observe the following precautions:
• Always use recently calibrated test equipment, with any correction figures taken into
account, so as to establish a known traceable limit of performance uncertainty. This
uncertainty must be allowed for in determining the accuracy of measurements.
• Ensure any user calibration routines are performed when necessary. On most power
meters it is also necessary to perform an auto-zero routine.
• Use the shortest possible connecting leads.
• Allow 20 minutes for the UUT to warm up, plus any extra time for other test equipment
being used.
5−4
ACCEPTANCE TESTING
Checking that the UUT powers up correctly
This test ensures that the 3020 powers up in a satisfactory manner and that the internal selftests do not report any errors. This test assumes that instrument is fitted in a PXI chassis and
that the supplied installation software is installed on the host controller.
• Apply power to the PXI chassis.
• Press the supply switch on the PXI chassis.
Wait for the operating system to complete its boot-up sequence.
• Double-click on the SigGen SFP icon.
The SigGen SFP now starts up. After completing its boot-up sequence, the indicator in the
top right-hand corner should be red.
• Click on Boot.
• Select the appropriate AF3020: resource from the list.
• Select the appropriate LO synth: resource from the list.
• Click on Boot Instrument.
While the modules are booting, the indicator turns amber.
• After a few seconds, the indicator turns green to show that the boot sequence has
completed successfully.

Attenuator
Perform the ALC flatness test first.
The attenuator test measures the RF level accuracy down to −113 dBm at a selection of
frequencies across the frequency band. An absolute RF level measurement at 0 dBm will
have already been taken during the previous ALC flatness test. With a spectrum analyzer
connected, the level at 0 dBm is measured again and is correlated with that measured on the
power meter. The lower levels are then measured on the spectrum analyzer relative to the
measurement taken at 0 dBm.

3 With the spectrum analyzer set to the same frequency as the UUT, use the marker
facility to measure the amplitude of the displayed signal. Using suitable span, filter and
attenuation settings, record the level measured on the spectrum analyzer at each of the
levels shown in Table 5-3.
4 Calculate the difference in the reading at 0 dBm to the reading taken on the power meter
at the corresponding frequency in the ALC flatness test and apply this correction to the
remaining measurements.
Example
The difference in the two readings at 0dBm is 0.08 dB. In this case, 0.08 dB must be added onto the
spectrum analyzer reading to obtain the result.
