●
WHILE <query> <> <value>
:
Waits until the <query> returns a certain <value>, e.g. a specific state is reached.
●
WAITKEY <message>
:
Displays a dialog box with a <message> and waits until the box is closed by the
user.

2.5.1 Signaling Application
The WCDMA signaling application is programmed as follows:
●
The application is controlled by SCPI commands with the following syn-
tax:
...:WCDMa:SIGN:...
●
After a
*RST
, the DL signal is switched off.
To activate the DL signal use
SOURce:WCDMa:SIGN:CELL:STATe ON
.
Query the cell state using
SOURce:WCDMa:SIGN:CELL:STATe:ALL?
. The result
ON,ADJ
indicates that the DL signal is available.
●
To initiate a connection setup in the CS domain use
CALL:WCDMa:SIGN:CSWitched:ACTion CONNect
.
Depending on the settings, this may also initiate a connection setup in the PS
domain.
To initiate a connection setup in the PS domain after the CS connection has been
established, use
CALL:WCDMa:SIGN:PSWitched:ACTion CONNect
.
To query the connection states use
FETCh:WCDMa:SIGN:CSWitched:STATe?
and
FETCh:WCDMa:SIGN:PSWitched:STATe?
.
●
To switch on dedicated downlink channels for reduced signaling use
CALL:WCDMa:SIGN:RSIGnaling:ACTion ON
To query the reduced signaling state use
FETCh:WCDMa:SIGN:RSIGnaling:STATe?
.
The following sections describe how to configure the signaling application. Some of the
listed configuration commands are not relevant for reduced signaling, but can never-
theless be executed before the reduced signaling mode is enabled.
The subsequent sections describe how to switch on the cell signal and the UE, how to
set up a CS or PS connection, and how to switch on dedicated DL channels for
reduced signaling. These sections distinguish between signaling and reduced signaling
mode. Some examples for actions possible after connection setup are also given.
