10.3.6 GPIB settings

Option: R&S NG-B105 GPIB (IEC 625/IEE 488) bus interface

For remote control over GPIB, you can address the R&S LCX over a channel address.

Access:

1. Press the [settings] key at the front panel.

2. In the device settings menu, select "Interfaces".

3. Select "GPIB Address".

The controller must address the instrument with the GPIB bus address.

GPIB Address

Set the GPIB channel address of the connected instrument.

10.4 Connecting the R&S LCX for remote access

This section briefly explains how to set up the remote control connections for the inter-

faces provided by the R&S LCX.

Establishing the LAN connection

The R&S LCX provides Ethernet (LAN) connectivity. Provided the corresponding rights

are assigned, you can use these interfaces for remote control and data transfer from a

controller PC. The controller PC must also be connected in the network.

The "LAN" connector is at the rear panel.

To connect the R&S LCX to the LAN:

1. Connect the "LAN" socket using an RJ-45 cable to the LAN.

By default, the R&S LCX configuration uses DHCP that assigns the IP address

automatically.

NOTICE! If the R&S LCX cannot obtain an IP address automatically, or cannot

establish the connection, the icon in the status bar turns red.

Possible reasons are that the LAN does not support DCHP or requires a specific

TCP/IP configuration, or that the connection is missing.

To troubleshoot the problem, proceed as follows:

a) Check if you have connected both the R&S LCX and the controller PC to the

LAN.

b) Consult your network administrator to request support and an IP address, if

necessary.

c) If necessary, assign the IP address manually as described in "Assigning the

LAN interface addresses manually" on page 169.

Establishing a USB remote control connection

You can use the USB B interface for remote control and data transfer from a controller

PC. Remote control over USB requires the VISA library, or the corresponding TMC or

CDC protocol drivers. The controller PC and the instrument must be connected at the

USB B interface.

The USB B connector is at the rear panel.

To connect the R&S LCX to the controller PC:

► Connect the USB B connector using a double-shielded USB cable to the controller

PC.

VISA detects and configures the instrument automatically when the USB connec-

tion is established. You do not have to enter an address string or install a separate

driver.

Establishing the GPIB remote control connection

Option: R&S NG-B105 GPIB (IEC 625/IEE 488) bus interface

You can use the GPIB bus interface for controlling the instrument remotely.

The USB B connector is at the rear panel.

169User Manual 1179.2260.02 ─ 08

To connect the R&S LCX to the controller PC:

1. Connect the IEC 625/IEEE 488 connector of the R&S LCX to the controller PC with

a double-shielded GPIB bus interface cable.

2. Configure the settings for remote control as described in "Assigning the GPIB

address manually" on page 173.

The controller must address the instrument with the GPIB bus address, see Sec-

tion 10.2.3, "GPIB interface (IEC/IEEE bus interface)", on page 155.

10.5 Adjusting interface addresses

Depending on the network capabilities, the TCP/IP address information for the instru-

ment can be obtained in different ways.

●

If the network supports DHCP (dynamic host configuration protocol), the address

information is assigned automatically. This mode enables you to establish a physi-

cal connection to the LAN without any additional instrument configuration.

●

If the network does not support DHCP, or if the instrument is set to use an alternate

TCP/IP configuration, you must set the addresses manually, see "Assigning the

LAN interface addresses manually" on page 169.

●

SCPI Raw Port

As an alternative, you can establish a raw TCP/IP connection using sockets for

sending raw SCPI commands to the instrument. To configure the connection,

assign the port, and, if necessary, the host name of the instrument, see "Assigning

the SCPI raw port and hostname manually" on page 172.

Assigning the LAN interface addresses manually

If the network provides DHCP, this protocol assigns the IP address automatically

(default setting). But you can also assign the address manually, if necessary. It is

assumed that you have connected controller PC and the instrument, see "Establishing

the LAN connection" on page 24.

To assign the IP addresses for the LAN interface manually:

NOTICE! Risk of network failure. Connecting to the network can cause network

failure. Errors can affect the entire network.

Consult your network administrator before performing the following tasks:

● Connecting the instrument to the network

● Configuring the network

● Changing IP addresses
