12 Channel Commands
:CHANnel<N>:PROBe:ECOupling
Command :CHANnel<N>:PROBe:ECOupling {NONE | AC}
The :CHANnel<N>:PROBe:ECOupling command sets the probe external
coupling adapter control. The 1154A and 1159A probes have external
coupling adapters that you can attach to the end of your probe. When you
attach one of these adapters, you should use the ECOupling command to
set the external coupling adapter control to match the adapter connected
to your probe as follows.
If an 1153A, 1154A, or 1159A probe is not connected to the channel you
will get a settings conflict error.
<N> An integer, 1-4.
Example This example sets the external coupling adapter for channel 1 to ac:
myScope.WriteString ":CHANNEL1:PROBE:ECOUPLING AC"
Query :CHANnel<N>:PROBe:ECOupling?
The :CHANnel<N>:PROBe:ECoupling? query returns the current external
adapter coupling value for the specified channel.
Returned Format
[CHANnel<N>:PROBe:ECOupling] {NONE | AC}<NL>
Example This example places the external coupling adapter value of the specified
channel in the string variable, strAdapter, then prints the contents of the
variable to the computer's screen.
Dim strAdapter As String ' Dimension variable.
myScope.WriteString ":CHANNEL1:PROBE:ECOUPLING?"
strAdapter = myScope.ReadString
Debug.Print strAdapter
NOTE
This command is valid only for the 1153A, 1154A, and 1159A probes.
Parameter Description
NONE Use this setting when there is no adapter connected to the end of your
probe.
AC Use this setting when you have an ac coupling adapter connected to the
end of your probe.
