About

Enables remote control of Siglent SPD3303X DC power supplies via SCPI over TCP/IP, supporting output control, measurement, timers, and network configuration.

README

基于 Siglent SPD3303X Quick Start Guide 及公开 SCPI 文档编写的 MCP Server,通过 TCP/IP (SCPI 端口 5025) 远程控制 SPD3303X 系列可编程直流电源。

⚠️ 注意:SPD3303X 使用端口 5025(不是 5024!)

适用型号:SPD3303X、SPD3303X-E、SPD3000X 系列

通道规格

通道 电压范围 电流范围 说明
CH1 0–32V 0–3.2A 可调,支持定时器
CH2 0–32V 0–3.2A 可调,支持定时器
CH3 2.5/3.3/5V 3.2A 固定 可选电压档位

快速开始

pip install -r requirements.txt

使用示例

> connect host=192.168.1.103
Connected to 192.168.1.103:5025

> configure_channel channel=CH1 voltage=5.0 current=1.0
CH1 configured:
  Voltage: 5.0 V
  Current Limit: 1.0 A

> set_output channel=CH1 state=true
CH1 output: ON

> measure channel=CH1
CH1: 5.001 V, 0.234 A, 1.170 W

> quick_snapshot
=== SPD3303X Quick Snapshot ===
Device: Siglent,SPD3303X,...
Track Mode: 0 (Independent)
  CH1: Set=5.000V/1.000A | Meas=5.001V, 0.234A, 1.170W
  CH2: Set=3.300V/0.500A | Meas=3.301V, 0.000A, 0.000W
  CH3: Set=3.300V | Meas=3.301V, 0.000A, 0.000W
