User’s Manual V1.00 RTX2300 – Smart ATE 11
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, Blue-
tooth™, etc.). The design of the RTX2300 is based on extensive experience within devel-
opment 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 multipurpose solution to simplify and cost-reduce the pro-
duction 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 modular 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 the 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, base-
band, 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 interconnection between 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 tester (such as the RTX2011/RTX2012 HS
DECT/DECT 6.0/CAT-iq RF Tester or Agilent 8960) and a PC for executing the test appli-
cation.

User’s Manual V1.00 RTX2300 – Smart ATE 12
B. Unpacking the RTX2300 Smart ATE
i. Initial Inspection

•USB cable (for communication between the RTX2300 unit and a PC)
•Optional items (modules, fixtures, QSK kit etc.) – if ordered
C. General overview of the RTX2300 Smart ATE Unit
The RTX2300 Smart ATE unit provides a wide range of external as well as internal con-
nectors. The connectors and functions can be divided into the following categories:
•Rear panel Connectors
•Internal Connectors
oShielded Fixture Bay Connectors
oController 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 along 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. The AUX Port can be used for
connecting external measurement equipment to the DUT, and it provides the fol-
lowing internal routing:
o10 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)
oOne 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)
oOne channel from the internal AD converter can be routed to the acquisition
unit
•Ground connector (): This ground connector is used for connecting all instru-
mentation together to avoid ESD problems.
•CLK Port (): Connector (type SMA female) for connecting to external equipment.
The port has the following functions:
oDUT CLK output to external frequency counter (e.g. Agilent 53181A)
o10MHz reference in (a reference signal from an external source is used as
reference for the optional internal frequency counter to measure the DUT
Clock)
o10MHz 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 con-
nector for Ethernet testing options. Furthermore, this connector can also be used
for PSTN/FXO/FXS testing options.

power supply of the DUT and should provide V+, V-, V+ sense 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 needed an
RF Switch Module (option) can be installed in the RTX2300, hence providing access
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 – connectors in the internal shielded 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 can be accessed either at the connectors in
the bottom part of the fixture bay (standard interface in the basic unit) or the optional
Quick-Swap Kit (QSK) connectors. Consequently, these connectors are used for connecting
the fixture to the signal lines. In the figures below the fixture bay connectors are shown in
both the basic configuration and with a QSK (fixture bay part) installed.

•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 to 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) available for (optional) extension
modules. Please note that the basic RTX2300 Smart ATE is not equipped 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.

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. Furthermore, each of the buttons can be configured as normal
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 closing 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 closing the lid and upon completion
of the test sequence the electrical motor will lift the lid. One signal for controlling
this mechanism is available from the SW API.

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 part 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 low-
level outputs. The two low-level outputs can be configured to operate in differential mode.
The level, frequency and configuration of the generators 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 con-
nectors. 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.
