Configure for GPIB, SCPI, and SICL

The following settings are used to configure the analyzer for remote control using SCPI commands.

How to Configure for SICL / GPIB Operation

Using front-panel
[softkey] buttons

Using Menus

  1. Press System

  2. then [Configure]

  3. then [SICL/GPIB]

  1. Click Utility

  2. then System

  3. then Configure

  4. then SICL/GPIB/SCPI


SICL / GPIB dialog box help



Talker/Listener Address  Sets the PNA address used to send and receive GPIB/SCPI commands to the system controller (external computer).

Use the National Instruments interface or the ACE (Keysight Connection Expert) interface to change the System Controller address. Use the PNA as the system controller of external devices. Learn about the PNA as controller.

See the rear panel of the PNA-X and N522x models.


SICL Enabled  When checked, the analyzer is capable of running GPIB programs on its computer to control analyzer functions. The programs must be run from a GPIB-capable programming environment (VEE, Visual Basic). This mode does not allow control of external GPIB instruments. To uncheck this box, exit the PNA application - (Click File, then Exit). The PNA restarts with the SICL enabled box unchecked unless Automatically Enable on Startup is checked.

Learn more about Configuring for VISA and SICL.

Note: When SICL Enabled is checked, the PNA VXI-11.2 interface is enabled, and if the PNA hard disk image is new enough to have the VXI-11.3 interface, it also enables that. Learn more about LXI/VXI.

Address  Sets the PNA address.

Automatically Enable on Startup  When checked, SICL Enabled is automatically selected when starting the PNA application.

LAN Sockets/Telnet

Provides ability to communicate with the PNA from a PC that uses a Windows, or non-Windows, operating system.

  • These settings are checked by default. If you have security concerns, clear these check boxes.

  • These settings remain after the PNA is shutdown and restarted.

Sockets Enabled  When checked, provides the ability to control the PNA from a remote SCPI program using port number 5025. See the C# example that illustrates how this is done.

Telnet Enabled  When checked, provides the ability to send single SCPI commands from a remote Windows, or non-Windows, PC to the PNA using port number 5024.

How to send single SCPI commands using Telnet:

  1. On the remote PC, click Start, then Run

  2. Type: telnet <computer name> 5024
    where <computer name> is the full computer name of the PNA. See how to find the computer name of the PNA.

  3. A Telnet window with a SCPI> prompt should appear on the remote PC screen.

  4. From the SCPI prompt:

    • Type single SCPI commands

    • If an invalid SCPI command is sent, the prompt will disappear. Press Enter or Ctrl C to recover the SCPI prompt.

    • To exit the telnet window click X in the upper-right corner.

    • To get a normal telnet prompt, press Ctrl  ] (closing bracket).

    • To close the normal telnet window, type Quit and press Enter.


HiSLIP has the same functionality as VXI 11 (SICL) with better performance. Therefore, it is enabled by default on the analyzer.

Address  0 by default. No change is necessary.

On the remote computer, use address string TCPIP0::<hostname>::hislip<address>. ("hislip" is case-sensitive).

SCPI Monitor / Input

GPIB Command Processor Console  Launches a window that is used to send single SCPI/GPIB commands from the analyzer keyboard.

Note: Press Control+Z , then enter, to close the console window.

Note: The Status Register system can NOT be used from the GPIB Console.

  • Type a valid command, with appropriate arguments and press enter.

  • Use the arrow keys to recall previous commands.

  • The console window may launch behind the analyzer application. Press Control+Tab to bring the console window to the top.

Monitor GPIB Bus  Enables monitoring activity on the GPIB.

Show GPIB Bus Monitor Window  Shows and hides the window monitoring GPIB activity.

Local and Remote Operation

The analyzer LCL and  RMT (Local and Remote) operation labels appear in the lower right corner of the status bar.

Note: The status bar is NOT visible when the analyzer is preset. See how to make the status bar visible.

To return to Local (front panel) operation, press the Macro / Local key

Sending the GPIB "GTL" (go to local) command also returns the analyzer to Local operation.

Sending the GPIB "LLO" (local lockout) command disables the front panel Local button.
