Average Power measurements are made using a factory-calibrated power detector.The detector measures power during the time that power control groups are gated on. Each Average Power measurement is computed from data taken during a 10 ms (one-half of one traffic frame) sampling period, ensuring that at least one out of the eight available power control groups in the half-frame will be gated on, even if the transmit data rate is 1200 bps.

For example, if the data rate is 9600 bps (full-rate) average power will be measured during all eight available power control groups. If the data rate is 1200 bps, Average Power will be measured during only one power control group. (The Test Set is able to determine the pseudo-random positioning of the power control groups that are gated on). The benefit of this measurement process is that measurement results will be consistent across all possible transmit data rates.

Use the “TRIG” command to trigger Average Power measurements when using single trigger mode. (The command “TRIG:AST ‘Arm’” will not trigger Average Power measurements).
