The instrument uses RS-232 interface (standard configuration) to communicate with the computer to complete all the functions of the instrument. Through the standard SCPI command, users can easily compile various collection systems suitable for themselves. -

Page 32: Scpi Language
in communication, the instrument can enable software handshake. The high-level language software engineer should compile the computer communication software strictly according to the following handshake protocol: The instrument command parser accepts only ASCII format, and command response also returns ASCII code. The command string sent by the host must end with NL ('\n'), and the instrument command parser does not start executing the command string until it receives the terminator. -
Page 33: Scpi Command Reference
8. SCPI Command Reference This chapter includes the following aspects: Command parser - understand some rules of command parser. Command grammar——Writing rules of command line Query syntax——Writing rules for query commands Query response——Query response format Command Reference This section provides all the SCPI commands used by the instrument, through which all the functions of the instrument can be fully controlled. -
