3.3.7.4 [Channel power On Off]
Enable or disable channel power measurement. After
pressing [Measurement setup], soft menu about parameter
setting for channel power measurement. Channel power is
used to measure channel power of transmitter. According
to channel bandwidth set by user, obtain absolute value of
main channel powerby integral of linear power.
pops up. Adjacent channel power is used to measure
adjacent channel power ratio of transmitter, absolute value
of main channel power and absolute value of adjacent
channel power are obtained by integral of linear power,
and then obtain adjacent channel power ratio.
3.3.7.5 [Occupied bandwidth On Off]
Enable or disable occupied bandwidth measurement. After
pressing [Measurement setup], softmenu about parameter
setting for occupied bandwidth measurement pops up.
Occupiedbandwidth is used to measure bandwidth occupied
by signal of transmitter. It can be measured by the ratio of
in-band power to total power within frequency span,
default to 99% (this valuecan be set by user).

3.3.8.2 [Tracking source On Off]
RF output completely synchronizes with spectrum received
in frequency sweep. Frequency of tracking source can’t be
separately set.
3.3.8.3 [Output power]
Power output range of tracking source is from 0 dBm to
-30 dBm.

Soft menu related with the measurement of tracking source
pops up.
Network measurement function of tracking source mainly
is used to measure amplitude-frequency characteristic; RF
output completely synchronizes with spectrum measurement,
and it can be used as scalar network system. When network
