Fields

Ch Loc:

The Ch Loc: field (NAMPS and NTACS system types only) sets the analog channel location that will be assigned to the mobile station by the Test Set as either an initial voice channel location or as a handoff channel location assignment.

For NAMPS systems, the choices are:

Lower - 10 kHz below standard wide analog channel

Middle - centered at the wide analog channel

Upper - 10 kHz above the standard wide analog channel

Wide - standard 25 kHz AMPS channel width

For NTACS systems, the choices are:

Narrow - standard narrow band NTACS channel, the default value

Wide - the JTACS channel

The :CEXT:SETT command is used to set the new channel location.

The query form of the command (that is, :CEXT:SETT?), can be used to determine the current setting of the Ch Loc right-hand field and CEXT:ACT? can be used to determine the actual setting of the Ch Loc: left-hand field.

The syntax and an example for NAMPS systems are as follows:

Syntax

:CEXTension:ACT?

:CEXTension:SETTing <‘><LOWER/MIDDLE/UPPER/WIDE><‘>

:CEXTension:SETTing?

Example

OUTPUT 714;"CALLP:NAMPS:CEXT:ACT?"

OUTPUT 714;"CALLP:NAMPS:CEXT:SETT ‘LOWER’"

OUTPUT 714;"CALLP:NAMPS:CEXT:SETT?"

ENTER 714;Last_ord_sent$

The syntax and an example for NTACS systems are as follows:

Syntax

:CEXTension:ACT?

:CEXTension:SETTing <‘><NARROW, WIDE CHAN><‘>

:CEXTension:SETTing?
