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.
6.4.4 Signal Path Settings
The signal path for input signals comprises an RF connector on a frontend, an RX module
connected to this frontend, a fixed or flexible baseband link and a baseband board or
signaling unit. Output signals use a reverse path with a TX module instead of an RX
module.
To define a signal path the RF connector and the RX/TX module must be selected. The
baseband board or signaling unit to be used is selected implicitly via the type of the
firmware application and the firmware application instance or used sub-instrument.
Typical commands for selection of RF connector and RX/TX module look like this:
●
ROUTe:<Application>:GENerator<i>:SCENario:SALone
●
ROUTe:<Application>:MEASurement<i>:SCENario:SALone
