Product-Specific Commands—Description

:SOURce[1..n]:POWer:ATTenuation?

Description

This query returns a value corresponding to the

internal power attenuation of the source.

*RST sets the attenuation to 0 dB.

Syntax

:SOURce[1..n]:POWer:ATTenuation?[<wsp>MA

Ximum|MINimum|DEFault]

Parameter(s)

Parameter 1:

The program data syntax for the first parameter is

defined as a <CHARACTER PROGRAM DATA>

element. The allowed <CHARACTER PROGRAM

DATA> elements for this parameter are:

MAXimum|MINimum|DEFault.

MINimum is used to retrieve the instrument's

smallest supported value.

MAXimum is used to retrieve the instrument's

greatest supported value.

DEFault is used to retrieve the instrument's

default value.
