specified channel.
Returned Format
[:CHANnel<N>:UNITs] {VOLT | AMPere | WATT | UNKNown}<NL>
Example This example places the vertical units for the specified channel in the
string variable, strUnits, then prints the contents of the variable to the
computer's screen.
Dim strUnits As String
myScope.WriteString ":CHANNEL1:UNITS?"
strUnits = myScope.ReadString
Debug.Print strUnits

UNITs can also be set using the CHANnel<N>:PROBe:EXTernal:UNITs command when
CHANnel<N>:PROBe:EXTernal command has been set to ON.
