Anrtisu Cell Master MT8212B, Руководство пользователя, Страница: 173 / 294

When the channel power measurement is on, a
CH PWR
icon appears to the left of the
graph. 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, the Cell Master will set the channel span equal to the integra-
tion bandwidth. When the integration bandwidth and channel span are set to
the same value, the Cell Master uses all the sampling points for integration,
providing the most accurate measurements. The ratio of the integration band-
width to channel span is kept constant. When the integration bandwidth is
changed, the ratio remains the same. The ratio can be changed by changing
the channel span. For example, when the integration bandwidth is doubled, the
Cell Master will double the channel span. Integration Bandwidth must be at
least one tenth of the channel span.
