CH<x>:PROBEFunc:EXTUnits
Description
This command sets the unit of measurement for the external attenuator
of the specified channel. 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 instruments. There is also a corresponding query that
returns the user--specified unit of measurement for the external attenua-
tor. Unless these units are set to the factory default string value of
”None”, they become the attenuated units of measurement for that
channel. It is assumed that the probe connected to the specified channel
is of the correct type to receive the output of the user’s external trans-
ducer or network.

H <str>
This can contain a string of up to eight characters to indicate the atten-

instrument attenuators only display the first two characters.
Example 1
CH4:PROBEFunc:EXTUnits ”Pa”
This command sets the unit of measurement for the Channel 4 external
attenuator.
Example 2

are Pascals.
