CDMA analyzer (continued)
Fast device tune measurement
E1999A-202 FDT-enhanced
CDMA analyzer (continued)
Fast device tune measurement
Input frequency ranges 411 to 420 MHz
450 to 484 MHz
824 to 934 MHz
1700 to 1980 MHz
Measurement method
Allows user definition of an RF source power
output sequence simultaneously with a Tx pow-
er measurement sequence each consisting of
10 or 20 ms duration steps with a user-defined
step size. Sequence can be defined to repeat
over a number of frequencies inside of a single
frequency band. This measurement requires
a test mode in the mobile station in order to
operate. Measures the total power in a
1.23 MHz bandwidth centered on the active
reverse channel center frequency in each step
period
Measurement data
capture period
0.313 μs
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 capture
range
Mobile station’s transmit power must be within
± 9 dB of the expected power per the ranging
configuration
Measurement accuracy
< ± 1 dB 15 to 55 °C for the fast mode, typically
< ± 0.5 dB (calibrated against average power
and within ±10 degrees of calibration tempera-
ture. Calibration must occur between 20 to
55 °C)
