Making Measurements Making the Adjacent Channel Power (ACP) Measurement

Avg Type - Choose the type of averaging between Pwr Avg (RMS) or Maximum.

Limit Setup - Allows you to access the menu to setup the limit values and conditions.

Abs Limit - Allows you to enter an absolute limit value ranging from −200.00 to +50.00 dBm with 0.01 dB resolution.

Fail - Allows you to access the following menu to select one of the logic keys for fail conditions between the measurement results and the test limits:

AND - Fail is shown if one of the relative ACP measurement results is larger than Rel Lim (Car) or Rel Lim (PSD) AND one of the absolute ACP measurement results is larger than Abs Limit.

OR - Fail is shown if one of the relative ACP measurement results is larger than Rel Lim (Car) or Rel Lim (PSD) OR one of the absolute ACP measurement results is larger than Abs Limit.

Absolute - Fail is shown if one of the absolute ACP measurement results is larger than Abs Limit.

Relative - Fail is shown if one of the relative ACP measurement results is larger than Rel Lim (Car) or Rel (PSD).

Rel Lim (Car)- Allows you to enter a relative limit value of the carrier level ranging from −150.00 to +50.00 dBc with 0.01 dB resolution. The default is −45.00 dBc for Offset A and −60.00 dBc for offset B.

Rel Lim (PSD)- Allows you to enter a relative limit value of the power spectral density level ranging from −150.00 to +50.00 dB with 0.01 dB resolution. The default is −28.87 dB for Offset A and −43.87 dB for offset B.

Offset Adv - Allows you to access the menu to change the following advanced offset parameters:

Sweep Time - Allows you to select the sweep time manually (Auto is the default).

Data Points - Allows you to select the number of data points. The automatic mode chooses the optimum number of points for the fastest measurement time with acceptable repeatability. The minimum number of points that could be used is determined by the sweep time and the sampling rate. You can increase the length of the measured time record (capture more of the burst) by increasing the number of points, but the measurement will take longer (2048 is the default in Auto).
