Printed Getting Started manual 3.2.2 Setting Up the Instrument The R&S EVSF1000 can be operated in a variety of places without detrimental effects on its features. Even the movement caused by transportation or mobile use does not impair its functioning.
Page 10 3.2.2.1 Connecting the R&S EVSF1000 to the Board Power The R&S EVSF1000 is connected to the board power (11 V DC to 32 V DC) of the flight inspection plane or the drone. The R&S EVSF1000 is inline with DO-160G, Section 16, Category A. (200 ms DC power interruption without reboot of R&S EVSF1000 for a minimum of 20 V DC input.)
Page 11 EVSF1000 Preparing for Use Using the connector plate, you can remove and replace the R&S EVSF1000 quickly and easily. While the tray remains connected to the aircraft permanently, you can remove the R&S EVSF1000 quickly and easily, without having to disconnect all cables from the instrument individually.

Localizers are posi- tioned in both areas, however they transmit their ILS signals using different frequen- cies, one that must travel farther, one for close-up.
Page 37 A predominant 150 Hz means that the aircraft is too low and needs to climb. 6.1.3 ILS Localizer and Glidepath Measurements and Results A single receiver board in the R&S EVSF1000 can measure data at two different receiver frequencies at the same time. Therefore, the ILS Localizer and Glidepath measurements can detect both course and clearance data simultaneously, and display the individual results.

Access VNC: [m] > Down arrow key The R&S EVSG-K4/-K5 options are firmware applications that add functionality to per- form GBAS and SCAT-I analysis on the R&S EVSF1000. The R&S EVSG-K4 option enables you to receive and analyze the very high frequency (VHF) data broadcast (VDB) signal-in-space transmitted from a ground-based aug- mentation system (GBAS) ground subsystem to the airborne subsystem.

Page 116 The GBAS specification [1] defines the TDMA timing structure, including timing budget of the VDB bursts, burst data contents and message encoding in great details. The R&S EVSF1000 receives the required training sequence, decodes the message according to [1] and demodulates the D8PSK modulated data automatically.
Page 117 The R&S EVSF1000 requires a valid PPS signal for the analysis of a GBAS/SCAT-I signal and for detection of the individual time slots. If the R&S EVSF1000 finds a valid PPS signal at its selected trigger connector, the status line of the display indicates "PPS Locked".

Page 178 Note: PPS input recommended. It is strongly recommended that you connect the PPS signal of the GPS receiver to the "PPS In" connector of the R&S EVSF1000. Although it is possible to store data on the R&S EVSF1000 without the PPS signal connected, this may lead to an incorrect assignment of the stored data to the actual GPS time.
Page 179 ® Common Instrument Settings R&S EVSF1000 GPS Configuration For details see Chapter 10.2.1, "GPS Data Synchronization", on page 160. "OFF" No PPS synchronization is performed. "PPS_IN rise" Stored GPS time is synchronized to the rising edge of the incoming PPS signal.
