Remote control
This chapter mainly describes the program control basics, program-control interface and configuration method and basic VISA
interface programming method of S3602 series vector network analyzers, as well as the concept of I/O instrument driver library. to
facilitate remote control of the user. Specific contents include:

Remote Control Interface
The instrument with the remote control function generally supports four kinds of remote control interface: LAN, GPIB, RS-232 and USB.
Specific port models depend on the instrument functions.
The remote control interfaces and associated VISA addressing character strings are shown in the following table.

Description
LAN
(LocalAreaNetwork)
VXI-11 protocol:
TCPIP::host_address[::LAN_device_name][::INSTR]
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:
9.1.1.1 LAN Interface
GPIB
(IEC/IEEE Bus Interface)
GPIB::primaryaddress[::INSTR]
Remote control can be realized by the connecting the
instrument through the port on the rear panel of the
instrument.
Comply with the IEC625.1/IEEE 418 bus interface
standard.For details, refer to: 9.1.1.2 GPIB interface
USB
(UniversalSerialBus)
USB::<vendorID>::<product_ID>::<serial_number>[::INST R]
Port of the rear panel of the instrument For details, refer
to:9.1.1.3 USB interface
9.1.1.1.
LAN Interface
The vector network analyzer can be controlled remotely by the 10Base-T and 100Base-T LAN computer. Various instruments in the
LAN are combined into a system for unified control with the computer in the network. In order to realize the remote control within LAN,
the vector network analyzer should be configured with the port connector, network card, relevant network protocol and network service
in advance. At the same time, the controlling computer in the network should be configured with the instrument control software and
VISA library in advance. Three working modes of the network card:
10Mbit/s Ethernet IEEE802.3;
100Mbit/s Ethernet IEEE802.3u;
1Gbit/s Ethernet IEEE802.3ab.
Connect the controlling computer and vector network analyzer to the common TCP/IP network through the network ports. Use the
RJ45 cable (shielded or non-shielded Class 5 twisted pair) between the computer and vector network analyzer. Use the packet
