7. Data rate

Type	Toggle

Units	None

Choices	“9.6” or “14.4”

Default	“9.6”

The Data rate ﬁeld determines the data rate associated with the HSCSD 2x2 call. Selecting '9.6' sets up a call at 9.6 kbit/s per timeslot (19.2 kbit/s) and selecting '14.4' sets up a call at 14.4 kbit/s per timeslot

(28.8 kbit/s).

The value of the Data rate ﬁeld can not be changed while a call is in progress.

8. Measure

Type	Toggle

Units	None

Choices	“Master” or “Slave”

Default (slave unit)	“Slave”

Default (other units)	“Master”

The Measure ﬁeld sets which of the uplink TCHs are to be measured or demodulated. The display updates (next to the Mobile reports and Peak Power displays) to show which timeslot is being analyzed.

The Measure ﬁeld also selects which analyzer level to use, either the Master input level (see page 34) or the Slave input level (see page 36).

The default is reset when you select the instrument type (see page 24).
