Test Mode Operating Mode
The test set can operate in two different operating modes (active cell mode or a test mode). Active cell mode is
the default operating mode and is used when emulating a normal GSM cell. Test mode (see
"CALL:OPERating" on page 266 for GPIB syntax) is used when it is not possible, or not desired, to
communicate via over-the-air signalling with the mobile station, but downlink stimulus and uplink
measurements are still needed. When test mode is selected, the choices of downlink stimulus (Test Function)
are:
• BCH (broadcast channel) (see "BCH Test Function Behavior" on page 526)
• BCH + TCH (broadcast channel + traffic channel) (see "BCH + TCH Test Function Behavior" on page 529)
• CW (continuous wave) (see "CW Test Function Behavior" on page 531)
See "CALL:FUNCtion" on page 249 for test function GPIB syntax.
Test Mode Operation
When the test set's operating mode is test mode:
• No over the air signaling is available.
• No capability to demodulate and decode uplink RACH bursts is available.
• Test mode features are determined by the test function: BCH, BCH + TCH, or CW.
• When the operating mode is set to test mode, auto triggering sets the trigger source to RF Rise. See "RF
Rise Trigger Source:" on page 149.
The test set's receiver remains on the uplink frequency determined by the broadcast channel see
"CALL[:CELL]:BCHannel[:ARFCn][:SELected]" on page 236 as long as receiver control is set to auto. If the
user needs manual control of the receiver parameters, receiver control should be set to manual. This gives
access to the receiver parameters of manual band, manual channel and manual frequency. See "Receiver
Control" on page 518.
NOTE "Setting the Active Cell Mode State" on page 510 has no effect while the test set is in test mode.
