Adjacent Channel Power Measurements

ACP

Adjacent channel power can be measured at frequency offsets of 0 to 3 MHz, and filter bandwidths of 10 kHz to 1.23 MHz with 100 Hz resolution. This measurement returns three, channel-tuned power values:

Center Channel - the channel power at the center frequency

Upper ACP Ratio - the ratio of the total power in the specified bandwidth at the specified offset above the center frequency, to the power at the center frequency.

Lower ACP Ratio - the ratio of the total power in the specified bandwidth at the specified offset below the center frequency, to the power at the center frequency.

This measurement must be calibrated using the ACP Cal field each time the tune frequency is changed. You must always remove power at the ANT IN or RF IN/OUT connector before calibrating channel power to ensure accurate calibration.

Channel Power Measurements

Chan Pwr

Channel power can be measured using one of two filters selected with the Ch Pwr Filt field on the CDMA ANALYZER screen:

1.23M - Channel power is the absolute power level of the RF signal in a 1.2 3MHz bandwidth centered around the RF channel or tune frequency setting.

30kHz - Channel Power measures the power in a 30 kHz band.

This measurement must be calibrated using the Chan Pwr Cal field each time the tune frequency is changed. You must always remove power at the ANT IN or RF IN/OUT connector before calibrating channel power to ensure accurate calibration.

Refer to the Agilent Technologies 8935 CDMA Base Station Tests Applications Guide for more information about channel power measurements.
