This encoder is used to test trunked mobile radios that use the MPT 1327
standard. It is primarily intended to be controlled using IBASIC programs running
on the Test Set's IBASIC controller or on an external controller.
The
Address Qualifier
address qualifier is a bit mask. It indicates the number of bits in the identity field
which have to be compared by a radio unit (RU) when it is deciding whether the
ALH or MOVE message is addressed to that RU.
The address qualifier is a two-digit decimal integer without leading zeros. It has
the range 0 through 20 and its default value is 0.
•
A value of 0 corresponds to no bits being compared (all RUs receive the ALH or MOVE
message).
•
A value of 20 corresponds to all bits being compared (the ALH or MOVE being
addressed to one specific RU).
•
For a value of M between 0 and 20, sub-divide the RU population into 2
field allows you to enter the address qualifier. The
