Power Meter Modes
The Spectrum Master offers an optional
High Accuracy Power Meter (option 19)
that uses external power sensors.
Setting the transmitter output power of
a base station properly is critical to the
overall operation of a wireless network.
A 1.5 dB change in power levels means a
15% change in coverage area. Too much
power means overlapping coverage which
translates into cell-to-cell self-interference.
Too little power, too little coverage, creates
island cells with non-overlapping cell
sites and reduced in-building coverage.
High or low values will cause dead zones/
dropped calls, lower data rates/reduced
capacity near cell edges, and cell loading
imbalances along with blocked calls.
High Accuracy Power Meter (Option 19)
For the most accurate power measurement
requirements select the high accuracy
measurement option with a choice of
sensors with:
• Frequency ranges:
10 MHz to 26 GHz
• Power ranges:
–40 dBm to +51.76 dBm
• Measurement uncertainties:
≤ ± 0.18 dB
These sensors enable users to make
accurate measurements for CW
and digitally modulated signals for
2G/3G and 4G wireless networks.
The power sensor easily connects to the
Spectrum Master via a USB A/mini-B
cable. An additional benefit of using the
USB connection is that a separate DC
supply (or battery) is not needed since
the necessary power is supplied by the
USB port.
PC Power Meter
These power sensors can be used with a
PC running Microsoft Windows
®
via USB.
They come with PowerXpert™ application,
a data analysis and control software. The
application has abundant features, such as
data logging, power versus time graph, big
numerical display, and many more, that
enable quick and accurate measurements.
High Accuracy Power, option 19, uses USB power
sensors for accurate measurements up to 26 GHz
PowerXpert on a PC uses the same
USB power sensors
