1 Key features
The test suites R&S SMx-K361 provide eCall tests with the sequencer tool
R&S CMWrun. The tests are performed on a connected in-vehicle system (IVS). The
tests are as closely aligned with the selected test specification as possible.
The following standards are supported:
●European Union regulation 2017/79, annex VI, Technical requirements for compati-
bility of eCall in-vehicle systems with the positioning services provided by the Gali-
leo and the EGNOS systems
●United Nations regulation ECE/TRANS/WP.29/GRSG/2017/12, annex 8, Test meth-
ods for the navigation solutions
The test equipment simulates a global navigation satellite system (GNSS). The
R&S CMWrun controls the test equipment via SCPI commands and the IVS typically
via vendor-specific commands. The test cases can be performed fully automatic, with-
out user interaction.
Table 1-1: Supported test cases
Test case Test purpose
1. Verify NMEA transmis-
sion from DUT
Checks that the GNSS receiver outputs the navigation parameter data to
external devices in NMEA-0183 format
2. Location accuracy (static
receiver)
Estimates the error in the evaluation of the plane view and altitude in the
autonomous static mode. A static location is simulated and the error between
actual and determined location is calculated
3. Location accuracy (mov-
ing receiver) open sky
Estimates the error in the evaluation of the plane view, altitude and velocity in
the dynamic mode. A certain trajectory is simulated and the error between
actual and determined location as well as the velocity error is calculated
4. Location accuracy (mov-
ing receiver) intermitted
reception and urban can-
yon
Estimates the error in the evaluation of the plane view, altitude and velocity in
the dynamic mode with signal impairments. A certain trajectory is simulated,
signal is faded and partly blocked. The velocity error and the error between
actual and determined location as well as the velocity error is calculated
5. Time-to-first fix (TTFF)
under cold start conditions
Determines the time to first navigation fix for a reset receiver. The ephemeris
and almanac data from all satellites are cleared and thus, the receiver has to
gain all data and the time to first fix is measured. One measurement step
comprises signal acquisition at the TX level of -130 dBm and the cold start of
the DUT, until it can acquire the signal again. The cold start is executed with
specified repetitions. The same is executed with the TX level of -140 dBm.
The averaged measurement time must not exceed 60 s for the signal level of
-130 dBm and 300 s the signal level of -140 dBm.

Test case Test purpose
6. Reacquisition time Evaluates the restore time for signal tracking for a certain GNSS constella-
tion after tracking was lost due to signal blockage. To simulate blockage, the
radio frequency signal is switched off for a specified time and the recovery
time is measured after the signal was switched on. One measurement step
comprises signal off, signal on, until the DUT can acquire the signal again.
Each step is executed with specified repetitions.
7. Tracking and acquisition
sensitivity
Verifies the sensitivity of the GNSS navigation module in signal acquisition
mode and in tracking mode. The acquisition time is measured with the signal
level of -144 dBm. The tracking time is measured with the signal level of
-155 dBm. The reacquisition time is measured after configurable signal
blockage with the signal level of -150 dBm. The acquisition, tracking and
reacquisition time must be within the required limits of ≦3600 s for TAcquisition,
≧600 s for TTracking, and ≦60 s for TReacquisition.

3 Test setup
The following figure provides an overview of the test setup. In this example, the instru-
ment R&S SMBV100A is used. The test setup with another supported instrument is
similar.
The test setup comprises the following components:
●An instrument, providing GNSS signals to the IVS for positioning.
Connect the RF output port of the instrument to the RF port of the IVS (GNSS
receiver).
●A computer executing the R&S CMWrun.
The computer controls the instrument via SCPI connections (typically LAN). It con-
trols the IVS typically via vendor-specific commands on a serial port interface.
●External attenuator is recommended for levels below -120 dBm, refer to "External
Power Attenuation" on page 20.

4.1 Preparation of controller PC
To set up the controller PC, install the base software of R&S CMWrun. No smart card
and no licenses are required for the R&S CMWrun with the R&S SMx-K361 eCall test
suite.
Refer to the sequencer user manual, section Installation.
Ignore the message indicating no license is found.
4.2 Preparation of instrument connection
1. For remote control of the instrument, configure the resource settings "Resources"
menu > "SCPI Connections". Configure the SCPI resource settings compatible to
the test instrument. For the control of R&S SMBV, the entry with an alias "SMBV" is
used. For the control of R&S SMW200A, the entry with an alias SMW is used.
Refer to the sequencer user manual, section Resources > SCPI Connections.
2. Configure measurement report settings.
For standard view of the measurement report, deselect "Treat "Ignored" as
"Failed"" in the configuration dialog of measurement report, tab "Fail Options".
To access the measurement report configuration dialog, proceed as follows:
a) To configure measurement report globally for all the tests, select "Resources"
menu > "Measurement Report..."
