6.1.1 Remote Control Interface
4051 series signal/spectrum analyzer is compatible only to two remote control interfaces: LAN and GPIB. As
shown in the following table:
Table 6.1 Types and VISA Addressing Character Strings of Remote Control Interfaces

(note 1)
Description
LAN
(Local Area Network) Original socket protocol:
TCPIP::host_address::port::SOCKET Remote control can be realized by the
connecting the instrument through the
network port on the rear panel of the
instrument. For details, refer to:
―6.1.1.1
LAN Interface‖ .
GPIB
(IEC/IEEE Bus Interface) GPIB::primary address[::INSTR] Remote control can be realized by the
connecting the instrument through the
port on the rear panel of the instrument.
Comply with the bus interface standards
of IEC 625.1/IEEE418. For details, refer
to:
― 6.1.1.2 GPIB Interface‖ .
Note 1: VISA stands for Virtual Instrumentation Software Architecture, which is a standard software interface
function library. Users may use the library to control the instrument via such interfaces as GPIB, LAN and
USB. Users should firstly install VISA library on the control computer and use it to remotely control the
instrument. See the User Manual of the VISA library to be installed for more details.

6.1.1.1 LAN Interface
The signal/spectrum analyzer may use RJ45 communication cables (shielded or unshielded Class 5 TP) to
connect to 10Mbps/100Mbps/1000Mbps Ethernet for remote control via the control computer inside LAN. In
