Channel power measurement
The channel power measurement measures the total RMS
power in a user-specified bandwidth. The following specifi-
cations apply for the default bandwidth of 1.23 MHz.
Range at RF input +30 to –80 dBm
Absolute power accuracy for in-band signal (excluding
mismatch error), 18 °C to 30 °C
+30 to –28 dBm ±0.6 dB
at RF input
–28 to –50 dBm ±0.8 dB
at RF input
–50 to –80 dBm ±1.0 dB
at RF input
ACPR measurement
Power range +30 to –20 dBm
at RF input
Dynamic range (referenced to average power of carrier
in 1.25 MHz BW)
Offset frequency Integ BW Dynamic range
750 kHz (BTS) 30 kHz –82 dBc
885 kHz (MS) 30 kHz –82 dBc
1.98 MHz 30 kHz –85 dBc
Relative accuracy ±0.9 dB
Power statistics CCDF measurement
Range at RF input
Maximum +30 dBm (average)
+40 dBm (peak)
Minimum –40 dBm (average)
Code domain measurement
Code domain power
Power range Mixer level (RF input power
minus attenuation) is between
–15 and –5 dBm
Accuracy
Relative range
0 to –10 dBc ±0.015 dB
–10 to –30 dBc ±0.18 dB
–30 to –40 dBc ±0.51 dB
Symbol power vs. time

is within 20 dB of total power;
averaged power over a slot)
Symbol error vector magnitude
