HP 8920A User Manual page 195

NOTE: In order to ensure that the Test Set makes the correct decisions regarding the presence of the
mobile stations's RF carrier, the Test Set's RF power meter should be zeroed before using the
Call Processing Subsystem. Failure to zero the power meter can result in erroneous RF power
measurements. See
information on manually zeroing the RF Power meter.
The CALL BIT screen should not be used to change any parameter that can be set
on any other Call Processing Subsystem screen. The contents of the applicable
fields on the CALL CONTROL screen and the CALL CONFIGURE screen are
not updated to reflect any changes made while using the CALL BIT screen. There
is no coupling between the CALL BIT screen and the Test Set.
For example: changing the value of the SAT color code field (SCC) in the forward
control channel mobile station control message (MS IntVCh) does not change the
setting of the field on the CALL CONTROL screen.
SAT:
When using the CALL BIT screen the user is responsible for setting the contents
of all messages used in a messaging protocol. When using the CALL BIT screen,
the Call Processing Subsystem sends the correct messages at the correct times as
defined in the applicable industry standard. Message content is the responsibility
of the user.
When the CALL BIT screen is displayed and the Call Processing Subsystem is in
the connected state, the Test Set constantly monitors the station's transmitted
carrier power. If the Power falls below 0.0005 Watts, the error message
Power Loss indicates loss of Voice Channel
Test Set will terminate the call and return to the active state.
