1. Getting Started
A. Introduction
The RTX2300 Smart ATE is a highly optimized automated test solution for calibration and
functional test in the production of wireless devices (including DECT, GSM, Wi-Fi, Bluetooth™, etc.). The design of the RTX2300 is based on extensive experience within development and installation of Automated Test Equipment (ATE) systems, and hence, key
parameters as handling-time, flexibility and size have been considered as part of the design
process.
The RTX2300 Smart ATE is a multipur pose solution to simplify and cost-reduce the production test environment dramatically compared to traditional “rack and stack” wireless
test implementations. The RTX2300 reduces the complexity and size of the ATE system
through the inclusion of mo dular instrumentation internal to the test unit, including a digital
volt meter, tone generator, and signal multiplexer. Optional internal instrumentation
includes a programmable power supply, and a frequency counter. These components allow
for the calibration and test of the baseband and audio portions of a Device Under Test
(DUT) without the need for additional external equipment.
The flexible nature of the RTX2300 Smart ATE enables a swift physical reconfiguration and
it can streamline th e manufacturing process, since in literally a matter of seconds, it can
be physically reconfigured to accommodate different products and test types. The RF
shielded compartment of the RTX2300 can be customized with a device-specific probe
fixture, including a pneumatic capture unit to automatically hold the DUT in place during
test. Furthermore, the RTX2300 can decrease overall product test time since it has been
designed to allow several units to be set up in parallel, enabling optimal use of RF, baseband, acoustic test resource, and effectively reducing the handling time of the DUTs.
The RTX2300 Smart ATE can be used for Printed Circuit Board (PCB) as well as final product
testing. It features a customization area that enables the interco nnection betwee n internal
and external measurement functionality and the DUT, hence reducing both space
requirements and complexity for the total test system. The flexibility of the RTX2300
simplifies the customization of the test platform, and enables economical replication. A
production test system can be implemented by using one or more RTX2300 Smart ATE
units in combination with an RF communication test e r (s uch a s the RTX2011/RTX2012 HS
DECT/DECT 6.0/CAT-iq RF Tester or Agilent 8960) and a PC for executing the test application.
User’s Manual V1.00 RTX2300 – Smart ATE 12
B. Unpacking the RTX2300 Smart ATE

C. General overview of the RTX2300 Smart ATE Unit
The RTX2300 Smart ATE unit provides a wide range of external as well as internal connectors. The connectors and functions can be divided into the following categories:
• Rear panel Connectors
• Internal Connectors
o Shielded Fixture Bay Connectors
o Controller Chamber Connectors
• Front Panel Functions
Each of these categories will be descibed in more detail in the following.
i. Rear Panel Connectors
The RTX2300 Smart ATE provides rear panel inputs/outputs for many functions. Below a
brief overview of the available connectors is provided alon g with a description of each of
the connectors.
User’s Manual V1.00 RTX2300 – Smart ATE 13
Available rear panel
• AUX Port (): Connector (type 25-pin DSUB female) for external acquisition unit
measurement channels (e.g. Agilent 34970A or similar). For a detailed pin
description please refer to section
v on page 112. Th e AUX Port can be used for
connecting external measurement equipment to the DUT, and it provides the following internal routing:
o 10 voltage measurement channels (20 wires) are routed to the Customized
Connector Block (CCB) selection matrix (for more information regarding the
CCB block please see chapter 5)
o One channel (2-wire) for current measurement is routed directly to the
Standard Connector Block (SCB) matrix (for more information regarding the
SCB block please see chapter 5)
o One channel from the internal AD converter can be routed to the acquisition
unit
• Ground connector (): This ground connector is used for connecting all instrumentation together to avoid ESD problems.
• CLK Port (): Connector (type SMA female) for connecting to external equipment.
The port has the following functions:
o DUT CLK output to external frequency counter (e.g. Agilent 53181A)
o 10MHz reference in (a reference signal from an extern al source is used as
reference for the optional internal frequency counter to measure the DUT
Clock)
o 10MHz reference out (a source signal from the optional internal frequency
counter and to external equipment)
• USB Interface (): This interface should be used together with a Windows®
based PC to control the test set and to query data from the test set. The USB
interface on the RTX2300 unit is a Type B receptacle, and hence, a standard USB
cable with Type A-B plugs can be used to connect the RTX2300 unit to a PC. Please
note that the external USB connector is internally connected to a 7-port USB HUB
to provide both USB connection and a serial connection. Furthermore, 4 of these
ports are available as USB ports for the 4 expansion slots. The USB ports support
USB 1.1.
• LAN/PSTN () (optional): This connector (RJ45 type) is optional and is a connector for Ethernet testing options. Furthermore, this connector can also be used
for PSTN/FXO/FXS testing options.
User’s Manual V1.00 RTX2300 – Smart ATE 14
• DUT Ext. Power supply (): Connector (type is XLR-4 male) for the external
power supply of the DUT and should provide V+, V-, V+ s ense and V- sense. Please
note that double pins for V+ and GND must be used.
• Fixture power supply connections (): Connector (type XLR-3 male) for the
fixture power supply (+12V, 5A) – i.e. the main positive supply for the RTX2300
unit.
• RF IN/OUT (): Connector (type SMA female) for the RF interface to the DUT. In
the standard configuration the RF is routed directly to the SCB block to enable
measurements of one antenna. If measurements of more antennas are need ed an
RF Switch Module (opti on) ca n be install ed in the RTX2300, hence pro viding acce ss
to more than one antenna at the SCB/CCB block through the RF IN/OUT connector
on the rear panel. When connecting the SMA male connector at the RF IN/OUT
connector it must be mounted with a maximum torque of 1.4 Nm.
• Air connector (): Connection for air supply for the pneumatic activators in the
RTX2300 Smart ATE.
ii. Internal Connectors
The RTX2300 is divided into two chambers:
• Shielded Fixture Bay Chamber – connector s in the internal shiel ded chamber are
used for connecting the fixture to the RTX2300.
• Controller Chamber – connectors in the main controller chamber are used for
connecting optional modules and customizing the internal routing of signals.
The connectors in each of the chambers are briefly described in the following.
Shielded Fixture Bay Connectors
The fixture bay is prepared with interfaces to the Smart ATE functionalities and external
RF equipment. The signal lines are filtered and ca n be accessed ei ther at the co nnectors in
the bottom part of the fixture bay (standard interface in the basic unit) or the optional
Quick-Swap Kit (QSK) connectors. Consequently, the se connectors are used for connecting
the fixture to the sig nal l ines . In th e fi gures bel ow the fixt ure b ay connectors are shown in
both the basic configuration and with a QSK (fixture bay part) installed.
User’s Manual V1.00 RTX2300 – Smart ATE 15

• Customization connector (output) (): This connector (2 x 32 pins female) is
used for the customization board for output signals (i.e. customization of the CCB
functionality).
• Customization connectors (input) (): In all three customization input con-
nectors (2 x 32 pins female) are available. The connector closest t o the rear panel
is also connected to the external AUX-port.
• Extension Module connectors (): In total there are five connectors (4 pcs. 2 x
32 pins female and 1 pcs. 60 + 4 pins female) avai lable for (optional) extension
modules. Please no te that the basic RTX2300 Smart ATE is not equ ipped with any
extension modules.
Please note that the customization connectors also are referred to as the option matrix
while the extension connectors are referred to as the instrumentation area.
iii. Front Panel Functions
The front panel on the RTX2300 Smart ATE provides many buttons for controlling the unit
(e.g. start/stop of the test sequence) – each of these are briefly described below. Please
note that the RTX2300 can be delivered both with (standard) or without (optional) the
shielded lid.
User’s Manual V1.00 RTX2300 – Smart ATE 18
Front panel functions
• Emergency stop (): The emergency button is a safety precaution. When pressed
all power to the RTX2300 is cut and all pneumatic valves controlled by the RTX2300
are released to disconnect the DUT.
• Push buttons / indicators ( & ): The two push buttons are intended to be
used as Start/Stop buttons. However, the button functionality can be customized
through the SW API. F urthermo re, ea ch of the buttons c an be c onfigure d as nor mal
input or as interrupt inputs with a programmable de-bounce time. The indicators in
the buttons can be used for showing the status of a test sequence (i.e. PASS /
FAIL). They are controlled from the SW API, and hence, the functionality of the
indicators can be customized as well.
• Top-lid closing mechanism (): The top-lid closin g mechanism is a magnetic
“lock” connected to an electrical motor which will pull down the lid. In the standard
configuration the test sequence is started when clo sing the lid and upon com pletion
of the test sequence the electrical motor will lift the lid. One signal for controlling
this mechanism is available from the SW API.

User’s Manual V1.00 RTX2300 – Smart ATE 20
i. Digital AC & DC Voltmeter (DVM)
The DVM is divided into two parts – an AC part and a DC part. The DC part is an 8-channel
digital voltmeter with an operational range from -10V to 10V in 10mV steps. It can operate
in two modes (static / differential) and it supports a wide range of scale configurations.
The AC par t is a 2-channel digital voltmeter. It can operate in static or differential mode
and it can be configured to measure RMS or peak value. A built-in attenuator enables
attenuation of the input signals and distortion measurements are also supported. Please
refer to the formula for THD outlined in section v on page 131.
ii. Tone Generator
The RTX 2300 has tree signal generators – one with high-level output and two with lowlevel outputs. The two low-level outputs can be confi gured to operate in differential mode.
The level, frequency an d confi guratio n of the g enerators can be changed from the SW API.
iii. Signal multiplexer
The RTX2300 Basic unit has 8 relays for signal switching. They are all available through
the option matrix (i.e. the customization connectors) and can be routed to the CCB connectors. Each relay has two sets of contacts.
In addition to the relays there are 16 connections to the expansion slots. These connections
can be used to route signals from the option-board in the expansion slot to the test bed
via the option matrix.
iv. GPIO
The RTX2300 Smart ATE has 16 digital output ports (8 sink outputs an 8 source outputs)
and 8 digital input ports. The port state of all ports can be controlled and read from the
SW API. The 8 digital inputs are 5V TTL logic and the sink and source outputs are as
outlined below.

User’s Manual V1.00 RTX2300 – Smart ATE 21
In addition to the digital input and output ports the RTX2300 also includes two DACs.
Please note that these DACs are only intended for DC values (i.e. they do not support audio
signalling).
v. Main functional blocks in the RTX2300
From a functional perspective the functionality of the RTX2300 Smart ATE can be divided
into the following categories:
• Fixture and box control
• Power supply
• Communication interfaces
Each of these categories will be outlined in more detail in the followin g.
Fixture and box control
To control the fixture fu nctionality the following signals are av a ilable:
• 4 sense signals (e.g. for detecting fixture position)
• 4 control signals (e.g. for motor or relay control)
• 1 signal for controlling the lid closing mechanism
• Signals for controlling the pneumatic slide is available through a pin header
connector
Power supply
The main power supply for the RTX2300 Smart ATE unit is a 12V external switch-mode
adaptor connected to the power-plug. This adaptor supplies all the internal circuitry
including the installe d modules. By adding an optional Programmable PSU module to the
RTX2300 unit the DUT can also be powered through the RTX2300. A more detailed
description of this optional module is given on page 82. An alternative way to supply the
DUT with power is to connect an external power supply to the DUT Ext. Power connector
on the rear panel of the RTX2300 (see figure below). The power supply to use for the DUT
can be controlled from the SW API.

Communication interfaces
The RTX2300 Smart ATE is equipped with one USB connector which serves as the only
communication interface between the PC with th e test applicat ion and the RTX2300 unit.
Inside the RTX2300 the USB connection is split into 7 USB ports through in an internal full
speed USB Hub. Furthermore, a serial communication port is available for DUT communication – i.e. the following communication interfaces are supported at the DUT:
• Four USB ports are available for the expans ion-slots (i.e. one for each slot)
• One USB port is converted to a UART for communication channel to the RTX2300
main board CPU
• One USB port is used as communication channel to the CCB
• One USB port is used as communication channel to the DUT (i.e. from the PC with
the test program directly to the DUT) through the SCB
Expansion slot USB interfaces
Each expansion slot (except the PSU module slot) is configured with a separate USB
connection, and hence, these are used for communicating with the installed modules.
RTX2300 control interface
This interface is used for communication to control the functions in the RTX2300 unit.
CCB USB interface
This interface is a general-purpose USB connection and it is connected directly to the CCB
interface.
SCB USB interface
This interface is a general-purpose USB connection and it is connected directly to the SCB
interface.
DUT serial communication configuration
To communicate with the DUT the RTX2300 has an UART for serial communication. Seen
from the PC the UART is a USB com-port. The UART is implemented as outlined below and
it has automatic level detection.
User’s Manual V1.00 RTX2300 – Smart ATE 23
Simplified DUT UART Port
As indicated in the figure above the UART has tree modes (can be controlled from SW):
• Disabled - In Disabled mode the UART is disconnected from the DUT. This is the
default mode after power up of the RTX2300.
• Normal - In Normal mode th e UART is connected to the DUT and ready for communication.
• Boot-mode - In boot-mode the RX-line is connected to ground-level to bring th e
DUT in boot-mode (RTX equipment). When the DUT is in boot-mode the UART must
be set to “Normal” before communication can be established.

E. Installing RTX2300 Options
As mentioned before, optional components for the RTX2300 are available – these can be
categorized into four different categories:
• Modules
• Quick-Swap Kit
• Fixture Kits
• Connectivity options
Installation of the firs t three categories will be outlined in more detail in the following.
i. Installing modules
The modules are installed in the controller chamber, and hence, the lid to the controller
chamber must be removed (see figure below). Please use a screwdriver to remove the four
screws holding the lid.
Removing the four screws holding the controller chamber lid
After removing the lid, the controller chamber is now accessible and the extra module(s)
can be installed in the empty extension slots (see figure below). Please be aware that the
right most connector is different from the other four connectors. This connector is reserved
for the programmable PSU module. Please make sure to install the module correctly in the
connector – i .e. with t he front s ide of t he modul e (i.e. the top-side of the PCB with all main
components mounted) pointing to the right. To ensure correct operation of the module
please also make sure to press the module tightly into the connector on the controller
board.
User’s Manual V1.00 RTX2300 – Smart ATE 25
Controller chamber - installing a module in an empty extension module slot
After installing the module(s) please put the controller chamber lid back on again and
tighten the four screws holding the lid. To use the modules from the test program a SW
package installation might be necessary. For more details on this issue please refer to the
specific module descriptions in chapter 4.
ii. Installing Quick-Swap Kit
The Quick-Swap Kit (QSK) is divided into two parts – a fixture bay part and a fixture part.
Installation of each of these parts will be outlined in the following.
Installing the fixture bay part of the Quick-Swap Kit
The first step is to remove the fixture part (if installed) to gain access to the fixture bay.
Place the QSK in the fixture bay close to the standard DSUB (male) connectors in the
fixture bay and connect the DSUB connectors on the QSK to the standard connectors in
the fixture bay. Please ensure tha t the connectors are connected correctly.
Next step is to connect the two p neuma tic conn ec tors o n t he QSK to th e con necto r s in the
fixture bay. When all connectors have been connected please mount the four spacers
(included in the QSK fixture bay part package) in the fixtur e bay a nd p lace the QSK o n top
of the spacers. Please ensure that the spacers are tightened. Mount and tighten the four
screws (also included in the QSK fixture bay part package) to fasten the QSK on top of the
spacers.

Installing the Quick-Swap Kit (fixture bay part)
Installing the fixture part of the Quick-Swap Kit
To enable easy installation of the fixture part QSK a new fixture plate should be used (i.e.
without any connectors or other equipment installed). However, the installation steps
outlined below should apply to all fixtures, but it could be necessary to remove some of
the items installed on th e fixture.
The first step is to mount the QSK spacers (included in the QSK fixture part package) on
the fixture. Place the QSK on top of the spacers. Mount and tighten the four screws as
shown in the figure below.
Please note that only the SCB connector, CCB connector and one of the connectors on the
top side of the QSK are mounted, and hence, connecting the QSK interface to the fixture
pins must also be done. This is, however, outside the scope of this section but for more
information on customizing the fixture please refer to chapter 6 (especially section D on
page 115).

iii. Installing a fixture kit
The first step is to remove the fixture part (if installed), hence unlocking the two locks on
each side of the fixture and removing it fro m the RTX2300 unit. The next step is to prepare
the new fixture and mount it in the fixture bay.
Installing a fixture kit in the RTX2300 Smart ATE unit
The installation process defers slightly depending on whether or not a QSK has been
installed:
With QSK installed:
If a QSK has been installed the installation process i s quite straightforward. Just make sur e
the (pneumatic, CCB and SCB) connectors on the fi x tur e QSK part are connected p r o perly
to the fixture bay part QSK connectors and secure the fixture by locking the two fixture
locks.
It is recommended that following steps are followed to mount the fixture insert into the
fixture bay of the RTX2300 unit.
1) The fixture must have a guide-pin (see picture 1)
mounted at each corner opposite to the quick-swapconnectors of the fixture insert.
2) In the fixture bay are there two guide-holes (see picture 2) in which the guide-
pins in which the guide-pins must fit.
Picture 1
Picture 2
User’s Manual V1.00 RTX2300 – Smart ATE 29
3) The mounting of the fixture insert in
the fixture bay must begin with an
alignment of the guide-pins with the
guide-holes (see picture 3).
When the guide-pins and holes are
aligned the connectors can be pressed
in place (see picture 4)
Without QSK installed:
To connect a fixture without a QSK installed the connectors on the fixture must be
connected directly to the standard interface in the fixture bay. If the fixture includes a
pneumatic slide the pneumatic tubes must be connected to the pneumatic connectors on
the back panel of the fi xture bay (see the figure on page 14 for an overview of the standard
fixture bay connectors). The next step is to connect the fixture SCB and CCB connectors
to the connectors in the bottom of the fixture bay. Please make sure to connect the fixture
correctly and secure the fixture by locking the two fixture locks.

F. System setup and installation of the RTX2300
The RTX2300 is the key component in an automatic test system setup an d it deliverers
most of the instrumentation (PSU, DVM, relays etc) needed to configure a production test
setup for a large variety of applications. Th e only external parts required are a Windows
based PC and an RF communication tester (if RF testing is required). Hence, a typical setup
could look like the one outlined in the figure below. It consists of a Windows based PC, an
RTX2012 RF tester (in case of a DECT product) and two RTX2300 Smart ATE uni ts. Please
note that one PC can control more than one RTX2300 unit (as indicated in the figure).

i. Connecting the RTX2300 Smart ATE
To configure a simple production test system (as the one outlined above) please follow the
four steps below to setup the above RTX2300 Smart ATE system.
1. Connect the RTX2300 units to the PC – the first step is to connect the RTX2300
units to a PC using the provided USB cables. In the example above both units are
connected to the same PC.
2. Connect external equipment to the RTX2300 units – if external equipment
is required (for example an RF tester) this must be connected to the relevant connectors on the rear panel. In the setup above an RTX2012 RF tester has been
connected to the two RTX2300 units (through the RF port on the rear panel).
3. Connect air for the pneumatic controls in the RTX2300 units – to enable
the pneumatic functionality inside the RTX2300 air must be connected to the air
connector on the rear panel of the RTX2300 units.
