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).

Starting and Stopping Recording
Access
: [Record]
Access VNC : [p]
When you press the key, data is recorded to the selected list, indicated in the status
bar ("Rec List"). The number of data sets that the list currently contains is indicated as
"Size". How often and when a new data set is entered in the list depends on the
"Trig-
ger Source" on page 222.
If enabled, raw, unprocessed I/Q data is also recorded to a separate file (see "Rec IQ"
on page 221).
Trigger Source
Access
: [Trigger] > "Source"
Access VNC : [k] > "F2"
Determines how often and when a new data set is entered in the list during recording.
"Time" Data is stored in regular time intervals, defined by "Time"
on page 220.
"Ext." Data is stored each time a trigger signal from a connected external
trigger device is received. The trigger device must be connected to
the "Trigger In" connector on the rear panel of the R&S
EVSG1000.
Trigger Edge
Access
: [Trigger] > "Trig Edge"
Access VNC : [k] > "F5"
For external triggering, this setting defines whether data is stored when the positive
(rising) or negative (falling) edge of the trigger signal is received. Select the key repeat-
edly to toggle between the two settings.
Recording a single data record (GBAS/SCAT-I mode only)
Access
: [Single]
Records the selected and currently displayed slot or frame only.
This function is only available for GBAS/SCAT-I mode (R&S EVSG1000-K4/-K5).
