Tx dynamic power measurement
Input frequency ranges
411 to 420 MHz
450 to 484 MHz
821 to 934 MHz
1700 to 1980 MHz
Measurement method
Measurement data
capture period
Captures a user-defined trace consisting of 20, 40, or 80 ms duration
power steps with user-defined step size produced by a test mode in
the mobile station under test; measures the total power in a 1.23 MHz
bandwidth centered on the active reverse channel center frequency in
each step period
1.25 ms
Measurement trigger
Tx signal output by the mobile station must provide a pulse (off-on-off)
followed by the stepped power burst beginning at the user-specified
output power
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
None. User must set the test set’s receiver power control field to manual
and set the receiver power to the expected full power of the power
sweep produced by the mobile station
Measurement accuracy
< ±1 dB 15 to 55 °C, typically < ±0.5 dB. (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 step duration time 20, 40, or 80 ms
Measurement step size
−0.01 to −90.0 dB
Measurement number of steps 0 to 99
Measurement result
A graph displaying the discrete power at each power step along with
numeric power results for each step
Measurement graphical controls Marker on/off with position, trace start step, trace span, and return to
default scale
Concurrency capabilities
None
