Electrical safety
If the information on electrical safety is not observed either at all or to the extent necessary, electric shock,
fire and/or serious personal injury or death may occur.
1. Prior to switching on the product, always ensure that the nominal voltage setting on the product
matches the nominal voltage of the AC supply network. If a different voltage is to be set, the power
fuse of the product may have to be changed accordingly.
2. In the case of products of safety class I with movable power cord and connector, operation is
permitted only on sockets with a protective conductor contact and protective conductor.
3. Intentionally breaking the protective conductor either in the feed line or in the product itself is not
permitted. Doing so can result in the danger of an electric shock from the product. If extension cords
or connector strips are implemented, they must be checked on a regular basis to ensure that they are
safe to use.
4. If there is no power switch for disconnecting the product from the AC supply network, or if the power
switch is not suitable for this purpose, use the plug of the connecting cable to disconnect the product
from the AC supply network. In such cases, always ensure that the power plug is easily reachable and
accessible at all times. For example, if the power plug is the disconnecting device, the length of the
connecting cable must not exceed 3 m. Functional or electronic switches are not suitable for providing
disconnection from the AC supply network. If products without power switches are integrated into
racks or systems, the disconnecting device must be provided at the system level.
5. Never use the product if the power cable is damaged. Check the power cables on a regular basis to
ensure that they are in proper operating condition. By taking appropriate safety measures and
carefully laying the power cable, ensure that the cable cannot be damaged and that no one can be
hurt by, for example, tripping over the cable or suffering an electric shock.

6. The product may be operated only from TN/TT supply networks fuse-protected with max. 16 A (higher
fuse only after consulting with the Rohde & Schwarz group of companies).
7. Do not insert the plug into sockets that are dusty or dirty. Insert the plug firmly and all the way into the
socket provided for this purpose. Otherwise, sparks that result in fire and/or injuries may occur.
8. Do not overload any sockets, extension cords or connector strips; doing so can cause fire or electric
hocks.
s
9. For measurements in circuits with voltages V
> 30 V, suitable measures (e.g. appropriate
rms
measuring equipment, fuse protection, current limiting, electrical separation, insulation) should be
taken to avoid any hazards.
10. Ensure that the connections with information technology equipment, e.g. PCs or other industrial
computers, comply with the IEC60950-1/EN60950-1 or IEC61010-1/EN 61010-1 standards that apply
in each case.
11. Unless expressly permitted, never remove the cover or any part of the housing while the product is in
operation. Doing so will expose circuits and components and can lead to injuries, fire or damage to the
product.
12. If a product is to be permanently installed, the connection between the protective conductor terminal
on site and the product's protective conductor must be made first before any other connection is
made. The product may be installed and connected only by a licensed electrician.
13. For permanently installed equipment without built-in fuses, circuit breakers or similar protective
devices, the supply circuit must be fuse-protected in such a way that anyone who has access to the
product, as well as the product itself, is adequately protected from injury or damage.
14. Use suitable overvoltage protection to ensure that no overvoltage (such as that caused by a bolt of
lightning) can reach the product. Otherwise, the person operating the product will be exposed to the
danger of an electric shock.
15. Any object that is not designed to be placed in the openings of the housing must not be used for this
purpose. Doing so can cause short circuits inside the product and/or electric shocks, fire or injuries.
16. Unless specified otherwise, products are not liquid-proof (see also section "Operating states and
operating positions", item 1). Therefore, the equipment must be protected against penetration by
liquids. If the necessary precautions are not taken, the user may suffer electric shock or the product
itself may be damaged, which can also lead to personal injury.
17. Never use the product under conditions in which condensation has formed or can form in or on the
product, e.g. if the product has been moved from a cold to a warm environment. Penetration by water
increases the risk of electric shock.
18. Prior to cleaning the product, disconnect it completely from the power supply (e.g. AC supply network
or battery). Use a soft, non-linting cloth to clean the product. Never use chemical cleaning agents such
as alcohol, acetone or diluents for cellulose lacquers.
Operation
1. Operating the products requires special training and intense concentration. Make sure that persons
who use the products are physically, mentally and emotionally fit enough to do so; otherwise, injuries
or material damage may occur. It is the responsibility of the employer/operator to select suitable
personnel for operating the products.

Basic Safety Instructions
2. Before you move or transport the product, read and observe the section titled "Transport".
3. As with all industrially manufactured goods, the use of substances that induce an allergic reaction
(allergens) such as nickel cannot be generally excluded. If you develop an allergic reaction (such as a
skin rash, frequent sneezing, red eyes or respiratory difficulties) when using a Rohde & Schwarz
product, consult a physician immediately to determine the cause and to prevent health problems or
stress.
4. Before you start processing the product mechanically and/or thermally, or before you take it apart, be
sure to read and pay special attention to the section titled "Waste disposal/Environmental protection",
item 1.
5. Depending on the function, certain products such as RF radio equipment can produce an elevated
level of electromagnetic radiation. Considering that unborn babies require increased protection,
pregnant women must be protected by appropriate measures. Persons with pacemakers may also be
exposed to risks from electromagnetic radiation. The employer/operator must evaluate workplaces
where there is a special risk of exposure to radiation and, if necessary, take measures to avert the
potential danger.
6. Should a fire occur, the product may release hazardous substances (gases, fluids, etc.) that can
cause health problems. Therefore, suitable measures must be taken, e.g. protective masks and
protective clothing must be worn.
7. Laser products are given warning labels that are standardized according to their laser class. Lasers
can cause biological harm due to the properties of their radiation and due to their extremely
concentrated electromagnetic power. If a laser product (e.g. a CD/DVD drive) is integrated into a
Rohde & Schwarz product, absolutely no other settings or functions may be used as described in the
product documentation. The objective is to prevent personal injury (e.g. due to laser beams).
8. EMC classes (in line with EN 55011/CISPR 11,
EN 55032/CISPR 32)

3 System Configurations
3.1 Standard Navigation
The R&S TSMX-PPS2 is used for GPS navigation in this configuration. The time
synchronization output and the ADR feature are not used for this setup.
The active GPS antenna is connected to the antenna port. Data connection and power
supply are provided from the host PC via USB.
The preferred host PC application is R&S ROMES. This software is not part of this
package. For details about R&S ROMES software, please follow this link to the product
homepage: http://www.rohde-schwarz.com/product/ROMES.html.
For test, evaluation and backup is the evaluation software “u-center” from u-blox
included on the accompanying CD-ROM. But any other customer software capable of
handling NMEA and/or the proprietary UBX protocol could be used to control the
device and evaluate the GPS data.

3.2 Time Synchronization
The R&S TSMX-PPS2 is used as a precision time reference in this configuration. The
precision time pulse signal (PPS OUT) from the device is used to synchronize the
R&S TSMU Radio Network Scanner family (see section "Navigation & Time
Synchronization" on page 11) but can also be used as a reference in customer specific
device setups.
In such a configuration the R&S TSMX-PPS2 is connected to the GPS antenna and
calculates continuously the GPS position. The accessory sync cable is used to bring
the trigger pulse from the PPS OUT port to the PULSE-IN connector of the R&S TSMU
respectively to the trigger in signal of the OEM device. The device is powered and
optionally controlled via USB.
Running PC software for R&S TSMX-PPS2 control is not mandatory in this mode as
far as the default settings are convenient for the application. As long as the
R&S TSMX-PPS2 can determine a GPS fix the precise PPS signal will be available.
Frequency, precision edge, pulse width and frequency could be altered and stored in
the device using u-center software (see section "Time Pulse Settings" on page 34).

3.3 Navigation & Time Synchronization
The R&S TSMX-PPS2 is used for navigation and time synchronization in this
configuration.
The connections for this setup are shown in Figure 3-3.
This setup represents the basic mode of operation for the R&S TSMX-PPS2.
The active GPS antenna is connected to the antenna input. The USB port is used for
navigation data and device configuration. This port is controlled by R&S ROMES
software.

3.4 ADR Navigation
The Automotive Dead Reckoning feature (ADR) of the R&S TSMX-PPS2 provides
100 % navigation coverage even in tunnels or building canyons with bad or missing
GPS coverage. ADR combines the calculated GPS position data with heading and
distance data from additional sensors. When GPS satellites are out of sight, the last
valid position is extrapolated using distance and angle information from a gyroscope
and a speed/direction pulse input.
It is also possible to use the time synchronization output in this mode.
The gyroscope for heading information is already embedded in the R&S TSMX-PPS2.
The distance signal and the direction information need to be derived from the vehicle
tachometer pulses and direction indication and fed via the accessory sensor cable into
the SENSOR IN port. Power supply and data connection are provided via the USB
cable.

4.2 Preparations
The accessory re-closable Dual Lock Fastener®3M strip should be used for attaching
the device. This strip has to be cut to fit along the bottom side of the housing as shown
in Figure 4-1. The counterpart of the Dual Lock Fastener®3M should be cut to have
similar length.
TM
Prior to applying 3M
with warm water and dishwashing liquid. A 50:50 mixture of isopropyl alcohol (IPA) and
water may also be used.
• To obtain optimum adhesion the bonding surface must be well unified, clean and
dry.
• Remove the backing plastic from the Dual Lock Fastener®3M without touching the
adhesive strip. Align the tape to the desired position at the bottom side of the
device and apply pressure to the tape. Firm application pressure develops better
bond strength.
Dual Lock TM the bottom cover of the device should be cleaned
• Turn the R&S TSMX-PPS with the Dual Lock Fastener®3M facing upwards.
• Align the remaining strip and press both sides together unit you hear an audible

4.3 Placing Hardware
4.3.1 Placing the R&S TSMX-PPS2
Standard Navigation (without ADR): No strict mounting recommendations. The
device could be positioned anywhere and in any direction (horizontally or vertically)
inside the vehicle or the trunk.
ADR Navigation: Calculations for ADR are based on quite sensitive and three
dimensional acceleration values. For that reason a strict horizontal mounting position
(with printed, brighter chassis side up) which is fastened tightly with the vehicle chassis
is absolutely important
Consider Mounting Requirements for ADR Navigation
Proper mounting position and tight connection with the vehicle chassis is
absolutely necessary when operating the R&S TSMX-PPS2 in “Automotive
Dead Reckoning” mode.
• Clean and dry the surface of the mounting position inside the vehicle in a similar
way as done for bonding the Dual Lock Fastener®3M on the device.
• Remove the protection plastics and press the R&S TSMX-PPS firmly against to
proper mounting position.
• Allow Dual Lock adhesive to cure for ten hours.
4.3.2 Positioning the Antenna
A magnetic mount antenna is part of the delivery. The antenna should be placed on a
metallic part of the vehicle chassis with free line of sight to the sky.
Without ADR: For optimum performance, the antenna should be placed in the middle
of the vehicle roof or trunk.
ADR Support: For an optimum ADR performance the placement of the antenna is
important and depends on the type of vehicle. Please follow these recommendations:
• Road Vehicle

4.5 Connecting Cables
Consider order of connection
When connecting the external cables it is strongly recommended to proceed
in the same order as listed in the following section.
Interchanging the order could end in unexpected system behavior and in
longer start times for a valid GPS position fix.
4.5.1 GPS antenna / GPS ANT
Connect the accessory active GPS antenna to the GPS ANT port.
Antenna connection only in un-powered mode
Connect the GPS antenna before powering the device via USB.
As the R&S TSMX-PPS2 calibrates the noise floor of the RF antenna at
power on delayed connection may result in a prolonged GPS acquisition time.
The R&S TSMX-PPS2 is designed for both active and passive antennas. This port
provides an open circuit and short cut protection.
Due to better navigation performance, R&S generally recommends to use active
antennas, especially the antenna shipped with the product.
For details on the accessory antenna characteristics, please refer to the u-blox
datasheet for the ANN-MS antenna. Link to website in section "u-blox Internet Pages".
R&S recommends the following antenna characteristics for customers using their own
antenna:
• Frequency: 1575 ±3 MHz
• Bandwidth: min. 10 MHz
• Polarization: RHCP
• Min Supply Voltage: O 3.0 V
• Max current: 50 mA
• Impedance: 50 F
• Min Noise figure: 1.5 dB
• min VSWR: 2
• Min. Gain: 15 dB
• Max. gain: 50 dB (minus cable and interconnect losses)

for the ADR feature.
Operating the R&S TSMX-PPS2 in standard navigation mode should leave
this port unconnected.
The sensor cable is part of the delivery. The plug has to be connected with the
SENSOR IN port of the R&S TSMX-PPS2. The opposite side needs to be wired with
the speed pulse and direction signal of the vehicle.
The sensor input at the R&S TSMX-PPS2 is electrically isolated via optical coupler.

4.5.2.1 Speed Pulse Signal
This signal is mandatory for using the ADR function. The signal should fulfill the
following recommendations:
• signal level range for high level: 3.5 V < Level < 15 V
• input frequency range: 0 Hz < Frequency < 2 kHz
• 0 Hz of the speed signal must be equal to a speed of 0 km/h
• speed signal should origin from the rear (not steered) wheel
The speed signal is normally available in the radio slot of the vehicle.
4.5.2.2 Direction Signal
The direction signal is optional and only improves the results of the DR algorithm. As
the forward/backward direction signal is not available in all vehicles, try to make use of
the reverse gear light signal.
• Valid Signal Level Range for high level: 3.5 V < Level < 15 V
• Level > 3,5 V -> backward direction
4.5.3 Sync Cable
• The Sync Cable (SMA -> BNC) is part of the delivery (see "Accessory
List").
The precision time pulse is available on the PPS port and used for synchronizing
external measurement equipment with the GPS time.
This port is normally connected to the trigger input of the R&S TSMU scanner (see
Figure 3-2). If not used this port may be left open.
The time delay for the time pulse strongly depends on the connected load capacity on
the PPS port and this is application specific. For synchronizing R&S TSMU radio
network scanners this does not harm as only the relative relationship of the pulses is
important.
Users with an absolute requirement for the pulse signal are able to configure a
dedicated time shift using u-center software (see section "Time Pulse Settings").
Load capacity Typical delay (approximately)
15 pF 0.6 – 3.7 ns
30 pF or 50 pF 1 – 4.5 ns

A valid GPS position fix with the transition into “Navigation State” is indicated by the
amber PPS LED starting blinking (see section "Top View - Status LEDs" on page 6).
ADR Navigation
R&S strongly recommends not moving the vehicle until a valid 2D/3D position
fix had been reported from the R&S TSMX-PPS2 when using ADR.
Moving the vehicle earlier could last in inadequate sensor calibration and
position localization errors.
The blinking frequency of the PPS LED is equivalent to the configured time pulse
frequency setting (see section "Time Pulse Settings" on page 38). The precision time
pulse is being output as soon as PPS LED starts blinking.
Proper Antenna Position
The GPS antenna must have a good line of sight to the sky to enter
“Navigation State” immediately.

5.3 ADR Calibration
Attention
his section is important for operating the R&S TSMX-PPS2 in ADR mode
T
with connected vehicle sensor signals (see section "ADR Navigation" on
page 12).
Users running the R&S TSMX-PPS2 in standard navigation mode or time
sync mode could skip this section and proceed to section "Navigation Mode"
on page 29.
5.3.1 General
For optimum ADR performance the system needs to learn from the internal sensors
(gyro & temperature) as well as from the provided vehicle signals (speed & direction).
The calibration process is initiated at the beginning of each drive as long as no
calibration data set is available from a previous drive (see Cold Start in section "Initial
Position Fix"). The calibration data set is kept in the volatile part of the memory and this
is provided with a battery backup that lasts for roughly about for three hours. So any
time the R&S TSMX-PPS is disconnected from power and this time period is expired
the device will re-calibrate.
For the time the R&S TSMX-PPS2 executes sensor calibration it is in GPS-only mode
and already provides navigation data. When calibration is finished to a certain degree it
switches into combined mode and combines Dead Reckoning (DR) calculations and
GPS and changes into “GPS + DR”.
As the calibrations are based on real position data a good GPS reception is necessary.
Requirements for ADR calibration phase
• ADR calibration process requires good GPS position fix
• The calibration should only be executed when driving forwards
Getting Started 1515.7236.02 - 02 25
Page 44
&S
SMX-PPS2 Starting Operation
R
T
The following parameters are being measured when calibrating:
• Sensitivity and zero point output of the internal Gyro
• Temperature drift of the Gyro
• Pulse ratio of the vehicle wheel ticks
The course calibration of the gyro and the resolution of the vehicle wheel ticks need to
be executed when doing sensor calibration.
The fine calibration of the sensor signals is an ongoing process for the whole drive.
For details please refer to the following sections and to the corresponding u-blox
documentation for the LEA-6R chipset. To get a link, please refer to section "u-blox
Internet Pages".
Validity of Calibration Data
As the R&S TSMX-PPS2 is only equipped with a short time back-up buffer for this
memory (backup time ~ 3 hours).
For that reason the device will run a new calibration every time the USB power was
disconnected for longer than this period. Calibration of the senor data will be kept.
5.3.2 Providing Vehicle Sensors Data
Even better the device knows to interpret the measurement data of the used sensors,
the more precise and quicker is the calibration process. The sensitivity and offset of the
embedded gyro is already programmed at factory for that purpose.
To speed up ADR calibration and to achieve proper function the system needs to know
the parameters of the external vehicle sensors.
a) Polarity of the direction signal
This setting is mandatory and important when the sensor cable is connected.
Default setting: “1 – High=Backward”
Direction Signal Polarity
ADR positioning will not work or is incorrect if the polarity setting is erroneous.
b) Resolution of the speed pulses
Setting optional but could speed up calibration process. System is able to calculate
resolution based on the driven GPS distance.
How to enter senor data:
ROMES: The sensor data is normally needed to be provided when loading
R&S TSMX-PPS2 driver. Please refer to the related ROMES documentation.
u-center: Please refer to section "Verifying ADR Settings" on page 33 how the enter.

5.3.3 Monitoring Calibration Status
The current state of the ADR calibration will be continuously reported from
R&S ROMES software. Please refer to the R&S ROMES manual for details.
For requesting the status of the ADR calibration, please refer to section "ADR
Calibration Status" on page 36.
There are different steps for calibration
• No calibration
• not yet calibrated (Calibrating)
• coarsely calibrated (Coarse Calib)
• finely calibrated (Fine Calib)
Minimal calibration state for ADR
A sufficient ADR performance can be expected when at least coarse
calibration has been achieved.
Fine calibration isn’t mandatory for ADR assistance.
If the calibration status reaches “Fine Calibration” the user can expect very good
ADR functionality and the device will use this feature to improve the accuracy
respectively to bridge short times with poor or missing GPS reception.
How to see if ADR works properly?
ROMES: the ADR state will be reported in the GPS status view (see R&S ROMES
documentation for details).
u-Center: whether ADR is used is displayed in the “Data View” of the u-center
software
Figure 5-1: GPS status overview
If calibration does not start measurement see troubleshooting section "ADR Calibration

5.3.4 Deleting Calibration Data
A delete of the sensor calibration data is necessary under the following circumstances:
• when changing the measurement vehicle
• when exchanging vehicle sensors
• when the GPS provides insufficient localization data especially after tunnels or
in situations with bad GPS coverage
R&S ROMES software will offer a dedicated action menu in the R&S TSMX-PPS2
software driver for deleting this data. Please refer to the R&S ROMES documentation
how to initiate this.

1. Check USB cable connection
2. Check if USB port is working well on the PC/Laptop/Tablet
3. Nothing helps U contact your local R&S service
8.2 Device not selectable in software
The virtual COM for the R&S TSMX-PPS2 (u-blox 6 GPS Receiver) might not being
listed in the Windows Device Manager.
1. Check if the USB device driver had been installed correctly. Depending on the
type of software application this has to be executed as a separate step:
a. u-center: no special measures are necessary for device driver
installation. This is integral part of the u-center setup.
b. R&S ROMES: device driver for u-blox LEA-6R module need to be
installed separately previous to starting software application. The
device driver is included in the CD-ROM (..\software\Drivers\
ublox_USB_driver.exe).
c. OEM application: the software originator is responsible for adding this
into the dedicated setup
2. Check the device driver version.
If necessary, install the latest driver version for LEA-6 chipsets from the u-blox
homepage. Please refer to section "u-blox Internet Pages" on page 44 for a link).
8.3 No GPS position fix
1. Check if GPS antenna is connected correctly.
2. Check if GPS antenna has free line of sight to the sky.
3. Signal is too poor or no signal U change to location with brighter sky view.
4. Check the GPS receiver configuration. If necessary reset to factory settings.
(see section "Recover GPS Factory Settings" on page 37).
5. For ADR users: Reset sensor calibration and restart calibration (see section
"Deleting Calibration Data" on page 28).

8.4 No Time Pulse (PPS)
1. Check your PPS cable connections
2. Check the position fix mode of your device. It has to be at least “2D” or “3D”
position. In this case the PPS LED has to blink.
a) If displayed “No Fix”, change your location to a place with brighter and
better sky view.
b) If Fix Mode is “2D” or even “3D” and PPS LED is blinking and no PPS
signal can be detected on the output, please send the device to your
local R&S service.
8.5 ADR Calibration fails
1. Check with u-center software whether the external sensor signals (speed and
direction) and the embedded gyroscope are being detected (see section
"Sensor Measurement Data" on page 35).
• If speed signal is missing check whether the Sensor Cable is plugged in
and connected correctly to the vehicle signals (speed & direction). Maybe
check the outputted signal with an oscilloscope.
• If the gyroscope signal is missing please send the device to our support,
because greater damage could be happened to the device
• If all signals are displayed go on with next step
2. Try to restart the calibration by clearing the latest calibration data to get sure
not to have any corrupted calibration data set (see section "Resetting Sensor
Calibration" on page 34).
3. Execute sensor calibration and monitor calibration status (see section "ADR
Calibration Status" on page 36). If it still fails, please proceed with next step.
4. Restore factory settings and repeat with step 3. If nothing helps please contact
the local R&S service.

8.6 Checking extern sensor signals
1. Check with u-center software whether the external sensor signals (speed and
direction) and the embedded gyroscope are being detected (see section
"Sensor Measurement Data" on page 35).
• If speed signal is missing check whether the Sensor Cable is plugged in
and connected correctly to the vehicle signals (speed & direction). Maybe
check the outputted signal with an oscilloscope. If the Sensor Cable is
firmly fixed to the car and measuring of the signals is only possible on the
Sensor Cable connector (the pin out could be find in section “Sensor cable
/ SENSOR IN” on page 20).
Measuring direction: Changing from forward to reverse gear has to be
combined with a change of the signal level (for example as a rule from 0 V
to 12 V, sometimes also reverse) between the DIRECTION+ and the
DIRECTION- pins.
Measuring speed: When moving the vehicle, there should be a
continuous square-wave, sinus- or a triangle-shaped signal (differs from
car to car) with a frequency proportional to the driven speed between the
SPEED+ and the SPEED- pins.
• If the gyroscope signal is missing please send the device to our support,
because greater damage could be happened to the device.
• If all signals are displayed go on with next step.
2. Check position of installation.
• The device has to be firmly fixed horizontal with the printed, brighter
chassis side up to the car chassis in a way that the device could not move
or turn (see section “Placing the R&S TSMX-PPS2” on page 15).
• If the placement of the device is correct proceed with the next step.
3. Restore factory settings to exclude faulty settings (see section “Recover GPS
Factory Settings” on page 37). In this regard consider that the configuration is
stored into BBR/Flash (U set corresponding tick in the u-blox GPS
Configuration window!).
4. Check with u-center software whether the external sensor signals could now
be detected.
• If the signals are available proceed with sensor calibration (see section
"ADR Calibration Status" on page 36)
• If the signals are still not present please contact the local R&S service.
