1. OverviewThis manual provides users with guidelines in writing commands for remote control of the LCR meter. It isconsidered that readers of this manual have carefully read the User Operation Manual of this product and are familiarwith operation methods this product.The LCR meter communicates with PC via RS232, USB or GPIB interface. For details of communication methods,please refer to different chapters of this manual. After the LCR meter is reliably connected to PC, user can controlthe LCR meter via programming commands. The LCR meter supports SCPI commands and part of GIPB Commoncommands1

2. Description to GPIB Common Commands*RSTFunction: Reset the instrument to factory setup.*IDN?Function: Query the instrument ID and return a string (unique identification code of the instrument).Return: Company name, Instrument model number, Version number*TRGFunction: Trigger the instrument externally.FETC?Function: Perform with *TRG command. Query measurement data manually. If the data automatic transmission functionis turned on, no need to use this command.*SAVFunction: Save files.Command: numeric value ,[string]Description: numeric value is internal file numbers 1 to 105.[string] is fileExample:name, max.10 strings.*SAV 1，“AB”Remarks: When sending this command, if the existing file is covered, there is no notification about it.*RCLFunction: Upload the existing files.Commands: numeric value Description: numeric value is internal file numbers 1 to 105.Example:*RCL 12

3. Introduction to SCPI CommandsSCPI (Standard Commands for Programmable Instrument) is standard commands for programmable instrumentsbased on IEEE 488.2 common commands. SCPI commands include two parts: IEEE 488.2 Common Commandsand Control Commands defined for SCPI instruments.Common Commands, as defined by IEEE 488.2, are supported by the instrument. Syntax and semantics of commoncommands must follow the rules of IEEE 488.2. Common commands are generally used to control reset, self-testand status operations in stead of measurement. For more details, please refer to chapter IEEE 488.2 CommonCommands.Control Commands defined for SCPI instruments are used to measure, read data, switch ON/OFF a function or amode and so on. This chapter includes the following contents:3.1 Command StructureThe SCPI is in a tree structure. The command on the top is called “root command” or called “root” in short. Toreach command of the lowest level, user must follow its route.Command terminatorIt is a symbol to end the command. For example: NL (Line break symbol, as 10 in ASCIIcode).Colon (:)It means a command level, going to the next level.Semic olon (;)It means multiple levels of commands.Question mark (?)It means query.Comma (,)Space ( )It is a break between multiple parameters.It is a break between commands and parameters. A symbolis used to representsspace In description of commands.It means contents of the original citation, which will not be processed by commandanalysis programm.Commands follow an asterisk are common commands.Quotation mark (“”)Asterisk (*) The following figure shows how to reach command of the lowest level by using colon and semicolon.3

If sending command: AA:BB:EE;FF;GGIt means the same to send below three commands::AA:BB:EE:AA:BB:FF:AA:BB:GG3.2 ParameterCharacter data and string dataCharacter data is consisted of ASCII characters. String data is consisted of ASCII charcters with quotation mark(“”).Numercial dataNumerical data includes integer number (NR1), Fixed point number (NR2), and Floating point number (NR3).
