Figure 5-7 shows the results of the measurement using a GSM signal source with an output

power level of –35 dBm.

When the channel power measurement is on, a

CH PWR icon appears to the left of the dis-

play. Channel power is calculated at the end of a sweep. An hourglass is displayed as the

calculations are performed.

NOTE: The channel span must be set equal to or larger than the integration

bandwidth. If not, Site Master will set the channel span equal to the integration

span. When the integration bandwidth and channel span are set to the same

value, the Site Master uses all the sampling points for integration, providing the

most accurate measurements. The ratio of the integration bandwidth to channel

span is kept constant. When the integration bandwidth is changed, the ratio re-

mains the same. The ratio can be changed by changing the channel span. For

example, when the integration bandwidth is doubled, the Site Master will double

the channel span.
