which automatically detects the type of LAN cable connected so you can use
any standard type of LAN cable to establish a network connection with the
R&S DDF205 (dedicated or non-dedicated).
Dedicated vs. non-dedicated network connections
There are two methods to establish a LAN connection with the R&S DDF205:
● A non-dedicated network (Ethernet) connection from the R&S DDF205 to an
existing network. The R&S DDF205 is assigned an IP address and can coexist
with a computer and with other hosts on the same network.
● A dedicated network connection between the R&S DDF205 and a single com-
puter. The computer must be equipped with a network adapter and is directly
connected to the R&S DDF205. The use of hubs, switches or gateways is not
required; however, data transfer is still made using the TCP/IP protocol.
Please refer to the Operating Manual for the steps to retrieve the IP address by

Press "DF"
to switch the R&S DDF205 to DF mode. The panel layout will change
to the default direction finding layout with focus on DF IF Panel. Follow the steps
as explained in chapter 2.3.2.4, "Settings – Receiver and Antenna",
on page 23 to confirm that your DF antenna is installed properly and recognized
by the system.
3. Use the main ROTARY KNOB or the numeric keypad to select the frequency
for which you want to conduct direction finding as explained in chapter 2.3.2.5,
"Basic Operation - Fixed Frequency Mode (FFM)", on page 25. Switch to DF
mode.
4. Choose an appropriate combination of "SPAN", "STEP" and "selectivity" in order
to optimize the direction finding bandwidth so that it matches the channel spacing of the RF band that is being monitored.
5. Also, choose a sufficiently small DF measurement time so that the measurement
can take place within a short time-frame (this is in particular important when the
observation is done on a moving vehicle).
In case the measurement takes place on a stationary system, use the built-in
compass to configure North Correction, as explained in "DF Antenna and Com-
pass Setup" on page 32. Alternatively use a standalone compass and manually
key-in the North Correction.
6. Use the PANEL key to change the focus to the Polar Panel
7. Set the DF Quality threshold to a value reasonably high so that reliable DF
measurement can be achieved for the channel that is being investigated.
8. Now the direction finding will most likely produce reliable bearing results, visible
by the stationary position of the yellow bearing arrow in the wind rose. The
heading indicator (white-color vane) in the wind rose corresponds with the compass value.

Digital Down Converter (R&S DDF205-DDC)
With R&S DDF205-DDC the R&S DDF205 becomes a multi-channel receiver. In
addition
to the basic receiver channel, another three receive channels are available.
These receive channels are realized with Digital Down Converters (DDCs) within
the IF bandwidth. Each DDC can demodulate AM, FM, PM, PULSe or IQ up to a
bandwidth of 1 MHz and CW, LSB and USB up to a bandwidth of 9 kHz. An independent audio volume and balance for each DDC as well as for the basic receiver
channel enable flexible audio mixing and recording. The DDC frequencies can be
set independently or coupled to the basic receiver frequency. The demodulation
parameters "Demodulation Mode", "Bandwidth", "Squelch state" and "Squelch
threshold" can also be set independently or coupled to the corresponding receiver
parameters.
The steps below will guide you through a typical scenario when using Digital Down
Converters.

Clean the outside of the R&S DDF205 using a soft, lint-free dust cloth.
Damage caused by cleaning agents
Cleaning agents contain substances that may damage the R&S DDF205, e.g.
solvent-containing cleaning agents may damage the front panel labeling or
plastic parts. Never use cleaning agents such as solvents (thinners, acetone,
etc), acids, bases, or other substances.
3.2 Storing and Packing
The R&S DDF205
can be stored at the temperature range quoted in the specifica-
tions (check the "Service" section in the Operating Manual). When it is stored for a
longer period of time the R&S DDF205 should be protected against dust. The original packing should be used, particularly the protective caps at the front and rear,
when the R&S DDF205 is to be transported or dispatched. If the original packing is
no longer available, use a sturdy cardboard box of suitable size and carefully wrap
the R&S DDF205 to protect it against mechanical damage.
3.3 Test Points
There are voltage and temperature checks at many test points of the R&S DDF205
modules. Some of these test points depend on each other. The error messaging
system
considers these dependencies and reports only the causal source of errors.

4 Software and Firmware Update
4.1 Retrieve Firmware and GUI Versions
The following key sequence allows to retrieve the various firmware revisions of the
R&S DDF205.
The "Firmware Version" refers to the version of the firmware which runs on the main
processor board. It provides the main control functions of the receiver.
The “GUI Version” refers to the GUI software in use:
If
●
the menu is obtained from the DDF205 with front control panel, it refers to the
Front Panel GUI.
If the menu is obtained from Remote Access, it refers to the Remote Access
●
GUI.
The GUI software runs on its own processor on the frontpanel hardware. This processor is different from the one on the main processor board and has its own operating system, which is different from the receiver firmware.
The "DSP Version" and "FPGA Version" are part of the firmware image and cannot
be updated separately.

firmware and GUI software: this will update all the images required for normal operation to the latest versions. The receiver firmware and GUI software will be updated
in the same procedure. This keeps the update process simple and prevents any
version conflict.
For DDF205 without front control panel only the receiver firmware needs to be
updated.
CD-ROM and Downloads
The R&S DDF205 is shipped together with a “DDF205 Software and Documentation CD ROM” which contains the same firmware and GUI versions as
in the R&S DDF205 at the time of shipment. The latest versions can be down-
loaded from GLORIS.
The CD-ROM will autostart and launch the opening menu where the various
options are available. If the CD-ROM does not autostart or if the files are
obtained from the company website, launch the menu by running the
start.htm in a suitable browser. Recommended is
Internet Explorer 7.
The next few sections explain the steps needed for updating the receiver firmware
and GUI software (for DDF205 with front control panel) or only the receiver firmware
(for DDF205 without front control panel) respectively.

4.2.1 Preparations
Required files and accessories
You will need the following files and accessories to perform an update:
A self-extracting DDF205 installation file.
●
USB flash drive with at least 256 Mb free space (A new or formatted one is
●
recommended). The MBR (Master Boot Record) of the flash drive will be overwritten to make it bootable.
Prepare USB Flash drive
The update process is done from the USB flash drive. The R&S DDF205 boots up
from the USB flash drive, and the update continues from there.
The following steps are necessary for installing files on the USB flash drive:
● Obtain the R&S DDF205 update installation file. This file can be retrieved from
either one of the locations mentioned at "CD-ROM and Downloads"
on page 50.

Installation. Allow access if there are security warnings. The dialog box
shown below will appear. It will ask for the path of the USB flash drive. Check
the drive letter before clicking "OK". This must be the drive letter which is
assigned to your USB flash drive after plugging it into your Windows host.
SFX image on USB Flash drive
This installer is built as a compressed SFX image. This is a self-extracting
image
which will install on the storage destination that is given as parameter:
here it is the USB flash drive. The image also contains a MBR section so that
it can boot-up from the USB flash drive.
Not every USB flash drive can be converted into a bootable drive. If a flash
drive still cannot boot-up after following the procedures above then it is
advised to change to a different brand USB flash drive.

SFX Installer
Be careful to use the correct drive letter that is assigned to the flash drive (e.g.
F: or G:). If a wrong drive letter is used (e.g. C:), the boot-loader might get
accidentally installed on the host system, which will result in a unusable host.
Software and Firmware Update
After double-checking the drive letter and clicking "OK", the SFX image will selfextract to the USB flash drive. This process will take less than one minute for a
USB 2.0 drive. In case a USB 1.1 flash drive is used it will take much longer.
The last step for the SFX installer is copying the MBR section to the USB flash drive.
This is shown in a console window.

From this point onwards, ensure that power to the R&S DDF205 is not interrupted. Failing to do so might result in a non-functional front panel.
The updater will then check if the FPC2 firmware (for the frontpanel key controller)
needs to be updated. FPC2 firmware will only be updated when the version on the
USB flash drive is newer than the version currently installed.

While updating a R&S DDF205, portions of the flash memory will be erased.
This
erase process may take up to two minutes, after which the new firmware
will be loaded. This will usually take about one minute. The update progress
is visualized by means of notification dialogs and progress bars.
Then, while the receiver resets, the GUI will be updated. The GUI runs on a dedicated processor (IPS1) and has its own operating system. This processor also
needs to reboot once the update completed.
At the end of the process, when the dialog below is shown, press ENT to reboot.
Now both the receiver firmware and the GUI are updated with the latest version.
This can be verified after reboot by following the steps shown in chapter 4.1,
