CDMA Tuned Channel Power Measurement
Input Frequency Range
• 30 MHz to 1000 MHz.
Input Connector
• RF IN/OUT (usable on antenna input (ANT IN) with relative power measurement
capability only).
Measurement Bandwidth
• Measures the total power in a 1.23 MHz bandwidth centered on the active reverse
channel center frequency.
Maximum Input Level
• +35 dBm (3 Watts continuous, 10 Watts allowable for 10 seconds per minute).
Measurement Range
•
−
50 dBm to +10 dBm (usable to +35 dBm with degraded accuracy).
Measurement Update Rate
• Typically 2 readings-per-second.
Measurement Accuracy
• Relative Mode (uncalibrated against average power)
•
0 to
−
10 dB relative level: ±0.1 dB.
•
−
10 to
−
20 dB relative level: ±0.2 dB.
•
−
20 to
−
40 dB relative level: ±0.5 dB.
• Calibrated Mode (calibrated against average power)
•
±1.0 dB at ±5° C from the calibration temperature.
Measurement Method
• Reports the average channel power for all active power control groups captured.
Measurement Period
• Measures power in a 1.23 MHz bandwidth over one-half of a CDMA frame (8 power
control groups) in full, half, quarter or one-eighth rate modes.
