2 RTX2018 Installation Requirements
2.1 RTX2018
To ensure that the user has the latest software and documentation for the RTX2018 prior to
installation, it is recommended to visit the RTX Download Center.
https://www.rtx.dk/en/design-services/download-center/
2.2 R&S CMW100
RTX recommends the user to register the included R&S CMW100 in the RTX2018 in the Rohde
& Schwartz Gloris system to get access to latest manuals for the CMW100.
https://gloris.rohde-schwarz.com/anonymous/en/pages/toplevel/home.html
2.3 Computer Requirements
The computer to be connected to the RTX2018/CMW100 must fulfil the minimum
requirements stated in the following table:

3 RTX2018 Pre-installation
3.1 System Overview
The RTX2018 tester can be installed in two ways:
•On a single PC, where both the CMW100 driver and RTX2018 DLL/GUI are installed
•On two PCs, where the CMW100 driver is installed on the PC connected to the
CMW100 hardware (sometimes referred as the “server”) and the RTX2018 DLL/GUI
on another PC
The two above options exist as the connection between the CMW100 driver and the RTX2018
DLL and is an IP connection (on port 5025). In the first case, the connection is the “Localhost”
or IP address 127.0.0.1
3.2 Driver Installation
The CMW100 driver needs to be installed on the server PC to which the CMW100 is connected
via USB. Please refer to [2] for a detailed description of the installation.
Please note that the RTX2018 requires installation of the following two Rohde & Schwarz
packages:
CMW_BASE (File name Setup_CMW1xx_BASE(RELEASE)_x.x.xx_64Bit.exe)
CMW_GPRF (File name: Setup_CMW1xx_GPRF(RELEASE)_x.x.xx_64Bit.exe)
This version of the RTX2018 has been tested with:
CMW BASE version 3.7.60
CMW GPRF version 3.7.30
3.3 Waveform Installation
For the BER measurements, it is necessary to install the included waveform files on the PC
connected with the CMW100 hardware.
The default location for these waveform files is: C:\RTX2018
When using the RTX Dialog DA14495 firmware (Note 1) in the DUT, the following files are
required to allow testing of the four modulation formats:
•gfsk.wv (for GFSK)
•pi2.wv (for PI/2-DBPSK)
•pi4.wv (for PI/4-DQPSK)
•pi8.wv (for PI/8-D8PSK)
Note 1: RTX firmware including BER/FER test capability and Prod Test Interface for remote
control
