CH<x>:PROBEFunc:EXTDBatten
Description
Use this command to specify the input --output ratio (expressed in deci-
bel units) of external attenuation or gain between the signal and the
instrument input channels.
The channel is specified by x. The value of x can range from 1 through
4 for four--channel instruments, or 1 through 2 for two--channel instru-
ments.
The query form of this command returns the user--specified attenuation
in decibels: 1X = 0 dB, 10X = 20 dB, 100X = 40 dB, etc.
This command is equivalent to selecting Attenuation from the Vertical
menu, and then either viewing or setting Ext Att(dB).
