The following settings are used to configure the analyzer for remote control using SCPI commands.
Using a mouse
Talker/Listener Address Sets the VNA 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 VNA as the system controller of external devices. Learn about the VNA as controller.
See the rear panel of the VNA-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 VNA application - (Click File, then Exit). The VNA 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 VNA VXI-11.2 interface is enabled, and if the VNA 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 VNA address.
Automatically Enable on Startup When checked, SICL Enabled is automatically selected when starting the VNA application.
Provides ability to communicate with the VNA from a PC that uses a Windows, or non-Windows, operating system.
Sockets Enabled When checked, provides the ability to control the VNA 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 VNA using port number 5024.
How to send single SCPI commands using Telnet:
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).
Enable Remote Drive Access When checked allows access to the hard disk. The default is unchecked. When unchecked, hard disk access is blocked and any of the following commands will return an error:
Show SCPI Parser Console Launches a window that is used to send single SCPI/GPIB commands from the analyzer keyboard. This window can also be used to capture the SCPI traffic used over HiSLIP.
IO Monitor enables monitoring activity on the remote control.
Clicking on the Configure button accesses the IO Monitor Configuration dialog to enable/disable this function.
Enabling the IO monitor provides detailed error message with debug information.
Example of Error message:
Disabling the IO monitor increases measurement speed.
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.
LCL appears when NOT under SCPI control
RMT appears when under SCPI control. The RMT label does NOT appear when under COM control. Remote operation disables the front panel keys except for the Macro/Local key.
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.
