Syntax

:OUTPut:POWer <wsp>

 

<value>[DBM]MINDEFMAX

Description

This command sets the through-power for the

 

instrument. The through-power is used to set

 

the attenuation of the filter.

Attfilter(dB) = ThroughPowerBase(dBm) - ThroughPower(dBm) + Attfilter@Base(dB)

You set the through-power by sending a value (default units are dBm), or by sending MIN, DEF or MAX, which specify the minimum, default and maximum values for the through- power.

The maximum value and the default value are

those values for which Attenuationfilter = 0dB. The minimum value is that value for which

Attenuationfilter is at its greatest. For example, if you have set INP:ATT 10 and INP:OFFS 2 and then switched UTP:APM ON, then the through power is set to 12dBm. The maximum through power, and the default through power, in this case is 22dBm. The minimum through power in this case is -38dBm.
