About

MCP server to remotely control Siglent SDM3000 series digital multimeters via TCP/IP SCPI protocol, enabling measurement, configuration, and data acquisition.

README

基于 SDM Programming Manual CN03-2 编写的 MCP Server,通过 TCP/IP (SCPI 协议,端口 5024) 远程控制 Siglent SDM3000 系列数字万用表。

适用型号:SDM3055X-E、SDM3055X、SDM3045X、SDM3065X

快速开始

pip install -r requirements.txt

通信协议

项目 说明
物理层 Ethernet (TCP/IP)
端口 5024
协议 Raw TCP Socket
命令 IEEE 488.2 + SCPI

可用工具(26 个)

连接

工具 说明
connect 连接 DMM
disconnect 断开
send_command 发送任意 SCPI 命令
get_id 设备 ID
reset 恢复出厂

测量(核心)

工具 说明
measure 一键测量:配置功能+量程+NPLC+自动调零 → 触发 → 读取值
read_value 快速读取当前值(不改设置)
configure_function 配置测量功能+量程(不读数,用于重复 read)
get_config 读取当前配置

测量功能:DCV/ACV/DCI/ACI/2W-Ω/4W-Ω/频率/周期/电容/通断/二极管/RTD/热电偶

相对值(NULL)

工具 说明
configure_relative 启用/禁用相对测量,设置参考值

限值测试

工具 说明
configure_limits 设置上下限、启用 PASS/FAIL 测试
get_limits 读取限值设置

统计

工具 说明
configure_statistics 启用/禁用、设置平均次数、清零
get_statistics 读取:平均值/最小值/最大值/标准差/峰峰值

dB/dBm 刻度

工具 说明
configure_scale 配置 dB 或 dBm 刻度

温度

工具 说明
configure_temperature 配置 RTD/热电偶类型、单位 (C/F/K)、参考端

触发

工具 说明
configure_trigger 配置触发源/斜率/延迟/计数
trigger 发送软件触发 (*TRG)

读数存储

工具 说明
configure_memory 设置存储点数、清零
get_memory_data 读取全部存储数据

直方图

工具 说明
configure_histogram 启用/量程/箱数/清零
get_histogram 读取直方图数据

系统

工具 说明
configure_system 蜂鸣器开关、通断阈值
get_network 读取网络设置
get_status 设备状态+错误队列
quick_snapshot 一键概览:功能+读数+NPLC+限值+相对+统计
