2.2.3.3 Using an Optional Battery Pack (R&S EVSG-B3) As an alternative to the fixed AC or DC power supply, the R&S EVSG1000 can be operated by a battery pack if the R&S EVSG-B2 and R&S EVSG-B3 options are instal- led. If the battery pack is installed and no DC power is supplied, the R&S EVSG1000 automatically switches to battery operation (during operation).
12 V DC, the internal battery is charged regardless whether the instrument is switched on or off. Starting Process The boot process of the R&S EVSG1000 takes about 30 seconds. Then the instru- ment automatically starts the measurement mode used before the instrument was switched off.

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 EVSG1000. 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.

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 EVSG1000 receives the required training sequence, decodes the message according to [1] and demodulates the D8PSK modulated data automatically.
The R&S EVSG1000 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 EVSG1000 finds a valid PPS signal at its selected trigger connector, the status line of the display indicates "PPS Locked".
