SOURce:<Application>:SIGNaling<i>:CELL:STATe ON
Starts the signaling generator, reserves all necessary hardware and system resources
and changes to the generator state "PENDing", then "ON". If the cell signal is already
turned on the command has no effect.
If the hardware and system resources are already assigned to another firmware appli-
cation, this firmware application is released in order to start the signaling generator; see
Resource and Path Management.
If the signaling generator cannot be started due to an unrecoverable resource conflict
(e.g. a missing software option) it remains in the OFF state. The SCPI error "-213, Init
ignored, ...", is generated. See also Causes for Task Conflicts.
Command synchronization
Before you use the generator signal, use the query
SOURce:<Application>:SIGNaling<i>:CELL:STATe:ALL? to ensure that the
signaling generator is turned on and that the cell signal is available (response: ON,
ADJ; see below).
SOURce:<Application>:SIGNaling<i>:CELL:STATe OFF
Switches the generator off, releases the hardware resources for other generators, and
changes to the generator state "OFF". If the generator is already turned off the command
has no effect.
SOURce:<Application>:SIGNaling<i>:CELL:STATe:ALL?
Returns detailed information about the signaling generator state. The first returned value
(main state) indicates whether the signaling generator has been turned on previously
(ON or OFF). The second returned value indicates whether a cell signal is actually avail-
able at the RF output connector (ADJ, if the main state is ON) or not (PEND or ADJ, if the
main state is OFF).
Connection states
After the cell signal is available, the mobile station under test can attempt a registration
so that it is possible to set up a network connection. The connection states and state
transitions are network-specific; refer to the description of the individual signaling appli-
cations.
5.4.4 Reliability and Error Indicators
Reliability and error indicators describe the validity of measurement results and the pos-
sible source of inaccuracies or errors.
