12 Channel Commands
:CHANnel<N>:PROBe:HEAD:SELect
Command :CHANnel<N>:PROBe:HEAD:SELect {<int> | <quoted_label_string>}
The :CHANnel<N>:PROBe:HEAD:SELect command selects the probe head
being used from a list of possible probe head choices. You can select by
the position number in the list of probe heads, or you can select by the
label given when the probe head was added.
<N> An integer, 1-4.
<int> Specifies the number of the head (or position) in the configure list. The
entry at the top of the list starts at 1.
<quoted_label_st
ring>
Specifies the label of the probe head given with the
:CHANnel<N>:PROBe:HEAD:ADD command.
Example This example add a couple of probe heads to the list then selects the
probe head using a number and a label.
myScope.WriteString ":CHANnel1:PROBe:HEAD:ADD 'N5445A:B1.5-2.5S'"
myScope.WriteString ":CHANnel1:PROBe:HEAD:ADD 'N5444A:2.92','foo'"
myScope.WriteString ":CHANnel1:PROBe:HEAD:SELect 1"
myScope.WriteString ":CHANnel1:PROBe:HEAD:SELect 'foo'"
Query :CHANnel<N>:PROBe:HEAD:SELect? {MODel | LABel}
The :CHANnel<N>:PROBe:HEAD:SELect? query returns a SCPI formatted
string of the selected probe head. Optional parameters are:
• MODel — Returns the model of the probe head.
• LABel — Returns the label of the probe head. This is the same label
given with the :CHANnel<N>:PROBe:HEAD:ADD command and that can
also be used with the SELect command.
If no parameter is specified, the MODel format is returned.
Example This example shows a few queries of the channel 1 probe head selection.
Dim strProbeHead As String
myScope.WriteString ":CHANnel1:PROBe:HEAD:SELect?"
strProbeHead = myScope.ReadString
Debug.Print strProbeHead ' Prints "N5444A:2.92".
myScope.WriteString ":CHANnel1:PROBe:HEAD:SELect? LABel"
strProbeHead = myScope.ReadString
Debug.Print strProbeHead ' Prints "foo".
myScope.WriteString ":CHANnel2:PROBe:HEAD:SELect? MODel"
strProbeHead = myScope.ReadString
Debug.Print strProbeHead ' Prints "N5444A:2.92".
