CDMA analyzer (continued)
Tuned channel power measurement
Input frequency ranges 411 to 420 MHz
450 to 484 MHz
824 to 934 MHz
1700 to 1980 MHz
Measurement method
Measures the total power in a 1.23 MHz
bandwidth centered on the active reverse
channel center frequency
Measurement data
capture period
0.3125 ms (very fast mode), 1.25 ms (fast
mode), or 10 ms (normal mode)
Measurement trigger 20 ms clock (frame trigger)
Maximum input level +37 dBm/1.23 MHz peak (5 W peak)
Measurement range
–61 to +30 dBm, usable to < –69 dBm/
1.23 MHz with reduced accuracy
Measurement level
ranging
Auto and manual
Measurement accuracy < ± 1 dB 15 to 55 °C, typically < ± 0.5 dB, for the
normal and fast modes
< ± 1.1 dB 15 to 55 °C, typically < ± 0.5 dB, for
the very fast mode (calibrated against average
power and within ± 10 degrees of calibration
temperature; calibration must occur between
20 to 55 °C)
Measurement resolution 0.01 dBm/1.23 MHz
Measurement result Channel power in a 1.23 MHz bandwidth
Concurrency capabilities Channel power measurements can be made
concurrently with all CDMA measurements that
support concurrency
Calibrate function
Calibrates the channel power measurement
over the entire operating frequency range of the
test set against the average power measure-
ment; no external cabling is required
