Adjacent Channel Power Measurements
The chapter "Channel Configuration" of the operating manual was extended to include adjacent channel
power measurements.

The ACP STANDARD softkey activates the selection of a digital mobile-radio
standard. The parameters for the adjacent channel power measurement are
set according to the regulations of the selected standard.

The AVERAGE LIN/LOG softkey switches between linear and logarithmic
averaging in case of logarithmic level display.
In case of logarithmic averaging, the dB values of the display voltage are
averaged, in case of linear averaging the level values in dB are converted into
linear voltages or powers prior to averaging. These voltages or powers are
averaged and then again converted into level values.
For stationary sinewave signals the two averaging methods yield the same
result.
Logarithmic averaging is recommended if sinewave signals are to clearly
stand out against the noise since, with this averaging, noise suppression is
greater while the sinewave signals remain unchanged.
