8.5 INPut Commands

:INPut:ATTenuation

Syntax

:INPut:ATTenuation <wsp>

 

<value>[DB]MINDEFMAX

Description

This command sets the attenuation factor for

 

the instrument. The attenuation factor is used,

 

with the calibration factor (see ) to set the filter

 

attenuation.

 

Attenuationfilter(dB) = Att(dB) - Cal(dB)

 

You set the attenuation factor by sending a

 

value (default units are dB), or by sending

 

MIN, DEF or MAX, which specify the

 

minimum, default and maximum values for the

 

attenuation factor.

 

The minimum value and the default value are

 

those values for which Attenuationfilter = 0dB.

 

The maximum value is that value for which

 

Attenuationfilter is at its greatest.

:INPut:ATTenuation?

Syntax

:INPut:ATTenuation? [<wsp>

 

MINDEFMAX]

Description

The query returns the current attenuation

 

factor, in dB.

 

Attenuationfilter(dB) = Att(dB) - Cal(dB)

 

By sending MIN, DEF, or MAX with the query

 

the minimum, default or maximum value

 

possible for the attenuation factor is returned.
