INPut[1]The INPut[1] subsystem controls the input attenuation an d impedance of the Agilent
E1446A’s “Input 1” BNC.
Subsystem Syntax INPut[1]
:ATTenuation <attenuation>
:IMPedance <impedance>
:ATTenuation
INPut[1]:ATTenuation <attenuation> controls the input attenuator of the “Input
1” BNC. Input attenuation can range from 0 to 31 dB in 1 dB steps.
