2.5.1 General Configuration
The LTE signaling application is programmed as follows:
●
The application is controlled by SCPI commands with the following syn-
tax:
...:LTE:SIGN:...
●
After a
*RST
, the DL signal is switched off.
To activate the DL signal use
SOURce:LTE:SIGN:CELL:STATe ON
.
Query the cell state using
SOURce:LTE:SIGN:CELL:STATe:ALL?
. The result
ON,ADJ
indicates that the DL signal is available.
●
To initiate a connection setup use
CALL:LTE:SIGN:PSWitched:ACTion
CONNect
.
To query the connection state use
FETCh:LTE:SIGN:PSWitched:STATe?
.
