8.6 OUTPut Commands

:OUTPut:APMode

Syntax

:OUTPut:APMode <wsp> OFFON01

Description This command sets the whether you set the attenuation factor, or the through-power to alter the attenuation of the filter.

When you are switching the absolute power mode ON, the attenuation factor (in dB) becomes the base value for the through-power (in dBm), at the time at which this command is processed. That is, if the attenuation factor is set to 32.000dB, and the absolute power mode is switched on, then the base value for the through-power is set to 32.000dBm. Use the
