Remote Control
IP address: 192.168.1.234
Subnet mask: 255.255.255.0
Gateway: 192.168.1.254(wireless router's IP address)
Step 4
Touch SSID button in [LAN] group, select an available Wireless LAN at functional field, and input
PASSWORD.
TIP
Due to the limitation of instrument hardware, instrument is unable to automatically acquire IP and
gateway, users must attain them from the administrator.
IP address cannot be the same as the LAN’s other equipment, otherwise instrument cannot
communicate.
For cryptographic Wireless LAN, users need to attain it from the administrator.
10.5
SCPI Language
SCPI-Standard Commands for Programmable Instruments is a common command that
Applent adopts and it is used to test instrument. SCPI is also called TMSL-Test and
Measurement System Language, which is developed by Agilent Technologies according to
IEEE488.2, so far it is widely used by equipment manufacturers.
Instrument built-in terminator is responsible for parsing user’s various command formats. Because terminator
is on the basis of SCPI protocol, but it is not fully consistent with SCPI, please read “SCPI command” chapter
before using instrument.
10.6
Handshake Protocol
Instrument adopts software handshake to reduce phenomenon of possible data loss or data error
during communication.
Instrument can start using software handshake, high-level language software engineer should
strictly do it according to the following handshake protocol to program communication
software:
Instrument terminator only accepts ASCII format, command response also returns ASCII
code.
Command string that sent by host must be ended with NL (‘\n’) mark, instrument
terminator will begin performing command string only after it receives end mark.
Instrument can set command handshake: instrument will return an identification code after it
receives command and finishes processing.
10.7
Handshake Identification Code
Instrument adopts the following error identification code:
