ACPMEAS Measure Adjacent Channel Power

ACPMEAS Syntax

The ACPMEAS command makes a measurement and calculates the

adjacent channel power (ACP) of a transmitter. The measurement

determines the leakage power that is in the adjacent channels from the

carrier. The result is the ratio of the leakage power in the adjacent

channel to the total power transmitted by the transmitter.

The instrument state is evaluated to determine if the ACP

measurement can be made with the current parameter settings. If the

ACP state is set to default, the best settings for the measurement

parameters will be used. If the ACP state is set to current, the

measurement will be made with the current settings even though the

results may not be optimum.

The instrument state parameters that can be affected by the

ACPMEAS command are frequency span, resolution bandwidth, video

bandwidth, and detection mode. If trace math or video averaging are

currently on, they will be turned off.

The optional command SNGLS or CONTS can be used to make a single

measurement, or to measure continuously. If no parameter is speciﬁed,

the measurement is only made once. The results generated by

ACPMEAS are categorized as follows and can be queried using the

respective query command shown:

• lower channel power (ACPLOWER)

• upper channel power (ACPUPPER)

• total power transmitted (ACPPWRTX)

• maximum adjacent channel power (ACPMAX)
