Conversational control using telnet (using port 23)
You can use telnet to perform conversational control by sending SCPI commands to the
E5061A/E5062A on a message-by-message basis. For telnet, the socket of port 23 is used
for communications.
In this example, in order to show you the control procedure using telnet, you control the
E5061A/E5062A (IP address: 1.10.100.50 and host name: e5061a) from the external
controller in the Windows environment.
Step 1. Open the MS-DOS command prompt screen.
Step 2. At the MS-DOS prompt, type telnet 1.10.100.50 or telnet e5061a and press the return key.
Step 3. The telnet screen opens.
Step 4. Type a command and press the return key; it is sent to the E5061A/E5062A and executed.
If you enter a command that queries some data, the query response is displayed below the
line you have entered the command.
Figure 2-4 shows the screen after using the :SYST:PRES command on page 479 to reset,
the :SENS{1-4}:FREQ:STAR command on page 418 and :SENS{1-4}:FREQ:STOP
command on page 419 commands to set the sweep start value and stop value to 1 GHz and
2 GHz respectively, and checking the settings.

Step 5. Select Disconnect from the Connect menu in the telnet screen (1 in Figure 2-4) to break the
connection to the E5061A/E5062A and select Exit from the Edit menu to exit the telnet. (In
other environment such as the UNIX environment, press ] while holding down the control
key. The telnet prompt appears. At the telnet prompt, type quit and press the return key.
The connection to the E5061A/E5062A breaks and telnet finishes.)
