10.2.1 GPS Data Synchronization
Together with the measurement results, the GPS data at the time of signal input is also
stored, if available (see
Chapter 11.6, "GPS Configuration" , on page 177). Storing
GPS data is useful to synchronize specific measurement results with the precise time
and location of the input signal. However, signal transmission via the RS232 serial con-
nection can cause delays in the stored GPS time as opposed to the actual time of
input. Therefore, it is useful to synchronize the stored GPS data to the PPS signal also
provided by the GPS receiver.

Recording GBAS/SCAT-I measurement results
In GBAS/SCAT-I mode, one record is stored for each slot, in a time interval of 62.5 ms,
as long as recording is active. Triggering is not supported. Recording is continued even
if the display update is temporarily stopped (by the "Pause" function).
You can start and stop recording from any measurement view using the [Record] key.
You can record the selected and currently displayed slot or frame only using the
[Single] key.
The record contains measurement values and the message bitstream for the slot. All
records are stored in a CSV file. This basic CSV file contains a data link for each
record in the list. The link points to a further CSV file which contains all human-reada-
ble texts for that record. All data files for the current recording are stored in a sub-direc-
tory that is exported together with the basic CSV file.
