SMART MEASUREMENTS FOR TRANSMITTER SYSTEMS
Commonly needed transmitter measurements are built in and can be accessed easily. These include field strength, occupied
bandwidth, channel power, adjacent channel power ratio (ACPR), and emission mask.
Occupied Bandwidth
Adjacent Channel Power Ratio
Emission Mask
OCCUPIED BANDWIDTH
This measurement determines the amount of spectrum used by a modulated
signal. The Site Master allows you to choose between two different methods
of determining bandwidth: the percent-of-power method or
the “x” dB down method.
ADJACENT CHANNEL POWER RATIO
Adjacent Channel Power Ratio is a common transmitter measurement. High
ACPR will create interference for neighboring carriers. This measurement
can be used to replace the traditional two-tone Intermodulation Distortion
(IMD) test for system non-linear behavior.
FIELD STRENGTH MEASUREMENTS
The Site Master can determine the effects of electromagnetic fields caused
by transmitter systems. Specific antenna factors of the connected antenna are
automatically taken into account, and field strength is displayed directly in
dBµV/m. The Site Master also supports a wide range of directional antennas.
If you are using a different antenna, Master Software Tools can be used to
edit the antenna list and upload the custom antenna list to the instrument to
accurately measure the maximum field strength.
EMISSION MASK
The emission mask is a segmented upper limit line that will display
frequency range, peak power and frequency, relative power and pass/fail
status for each segment of the mask. The emission mask must have at least
two segments. Emission mask adjusts to the peak power value of transmitted
signal level per government emission mask requirements.
