Power vs. time and power control measurement
Absolute power measurement
Using 5 MHz resolution bandwidth
Accuracy
0 to –20 dBm ±0.7 dB (nominal)
–20 to –60 dBm ±1.0 dB (nominal)
Relative power measurement
Accuracy
Step range ± 1.5 dB ±0.1 dB (nominal)
Step range ± 3.0 dB ±0.15 dB (nominal)
Step range ± 4.5 dB ±0.2 dB (nominal)
Step range ± 26.0 dB ±0.3 dB (nominal)
Multicarrier power measurement
This measurement is used for adjusting multicarrier power
amplifiers to transmit well balanced multiple carriers. The
measurement is similar to a combination of those for ACPR
and intermodulation distortion product measurements
giving in-channel and out-of-channel performance results.
The results are displayed for the different frequency offsets
either in relative power to the carrier in dBc or in absolute
power in dBm.
Minimum carrier power –15 dBm (nominal)
at RF input
ACPR dynamic range, RRC weighted, 3.84 MHz
two carriers noise bandwidth
5 MHz offset –64 dB (nominal)
10 MHz offset –68 dB (nominal)
ACPR accuracy, two carriers
5 MHz offset, ±0.70 dB (nominal)
–48 dBc ACPR
Spectrum emission mask measurement
The spectrum emission mask measurement measures
the in-channel and out-of-channel spurious emissions to
provide useful figures of merit for spectral regrowth and
emissions produced by components and circuit blocks. Up
to five pairs of offsets/regions can be defined in which the
user can specify the start and stop frequencies, resolution
bandwidth, and the start and stop amplitudes of the mask.
Minimum power –20 dBm (nominal)
at RF input
Dynamic range, relative
2.515 MHz offset –77.9 dB (–82.8 dB, typical)
1980 MHz region –72.2 dB (–77.2 dB, typical)
Sensitivity, absolute
2.515 MHz offset –88.9 dBm (–93.9 dBm, typical)
1980 MHz region –72.9 dBm (–77.9 dBm, typical)
Accuracy
Display = Abs Peak Pwr ±0.60 dB (±0.40 dB, typical)
Display = Rel Peak Pwg ±0.25 dB
Occupied bandwidth measurement
Occupied bandwidth (OBW) measurement measures the
frequency bandwidth corresponding to 99 percent of the
total transmitted power.
Minimum carrier power –20 dBm (nominal)
at RF input
Frequency resolution 100 Hz
