182 Agilent Infiniium 90000 Series Oscilloscopes Programmer's Reference
12 Channel Commands
:CHANnel<N>:INPut
Command :CHANnel<N>:INPut {DC50 | DCFifty}
The :CHANnel<N>:INPut command selects the input coupling and
impedance for the specified channel and is always DC coupling, 50
Ω input
impedance. This command is provided for compatibility with other
Infiniium oscilloscopes.
<N> An integer, 1 - 4.
Example This example sets the channel 1 input to DC50.
myScope.WriteString ":CHANNEL1:INPut DC50"
Query :CHANnel<N>:INPut?
The :CHANnel<N>:INPut? query returns the selected channel input
parameter and is always DC coupling, 50
Ω input impedance. .
Returned Format
[CHANnel<N>:INPut] DC50<NL>
Example This example puts the current input for channel 1 in the string variable,
strInput. The program then prints the contents of the variable to the
computer's screen.
myScope.WriteString ":SYSTem:HEADer OFF"
myScope.WriteString ":CHANNEL1:INPUT?"
strInput = myScope.ReadString
Debug.Print strInput
