5 Remote Control
This chapter includes the remote control basis as well as the remote interface and its configuration method of the
S2438 series microwave power meter, and also briefly describes the concept and classification of the I/O driver
library so that the user can have a preliminary knowledge about the remote control of this instrument. The specific
content includes:
Remote control basis
Remote interface and its configuration
Basic programming method of the VISA interface
I/O library
5.1 Remote Control Basis
5.1.1 Remote interface
The instrument with the remote control function generally supports three remote interfaces: LAN, GPIB and USB. The
type of the port supported by the instrument of a specific model is determined by the function of the instrument.
Table 5.1 Remote Interface Type and VISA Addressing String
Remote Interface
VISA Addressing String (Note 1)
Description
LAN
(Local Area Network)
Raw socket protocol:
TCPIP::host_address::port::SOCKET
Controller realizes remote control by
connecting the instrument via the
network port on the rear panel of the
instrument.
For the specific protocol, please refer
to: 5.1.1.1 LAN interface.
GPIB (IEC/IEEE Bus
Interface)
GPIB::primary address[::INSTR]
Controller realizes remote control by
connecting the instrument via the port
on the rear panel of the instrument.
The
IEC
625.1/IEEE
418
bus interface standard is observed. For
details, please refer to: 5.1.1.2 GPIB
interface.
USB
(Universal Serial Bus)
USB::<vendor ID>::<product_ID>::
<serial_number>[::INSTR]
Instrument
‟
s rear panel port For
details, please refer to: 5.1.1.3 USB
interface.
Note 1: VISA or Virtual Instrumentation Software Architecture is a standard software interface function library which
can be used by the user to control the instrument through GPIB, RS232, LAN and USB interfaces. The user should first
install the VISA library on the control computer and use it to implement remote control of the instrument. For details,
please refer to the user manual of the installed VISA library.
