Power Supply Waveform Tools (Web-based)

A unified, lightweight web-based toolkit designed to visualize and edit test scripts for DC Power Supplies. This project currently supports Chroma 62000P (SCPI Sequence) and GW Instek PSW (CSV) formats, enabling engineers to verify automotive test profiles (e.g., ISO-16750-2 starting profiles) directly in the browser without installing proprietary software.

✨ Included Tools

1. Chroma 62000P Editor

A full-featured Waveform Editor for Chroma 62000P Series (List Mode / Sequence).

• Features:
  • Visual editing of Voltage, Time, and Slew Rate (V/ms).
  • Supports Program Linking (PROG:LINK) and Loop Counts (PROG:COUNT).
  • Real-time chart updates.
  • Export: Generates valid _W_mem.csv files for import into Chroma SoftPanel.

2. GW Instek PSW Viewer

A Waveform Previewer for GW Instek PSW Series.

• Features:
  • Parses PSW-formatted CSV files (.csv).
  • Intelligent header detection (automatically skips memo lines).
  • Visualizes Step-based voltage transitions.
  • Note: This tool currently serves as a viewer to verify waveform shapes before testing.

📝 Supported File Formats

Chroma 62000P (SCPI Sequence)

The editor expects (and generates) standard SCPI command lists:

CONF:REM ON
PROG:SEL 1
PROG:COUNT 1
PROG:LINK 0
PROG:SEQ:VOLT 12.0
PROG:SEQ:VOLT:SLEW 10
PROG:SEQ:TIME 0.5
...

###GW Instek PSW (CSV)The viewer looks for the Step header row and automatically detects Time(sec) and Voltage (V) columns.

memo,Sequence Example...
Cycle,1,1,7
...
Step,Point,Output,Time(sec),Voltage (V),Current (A)...
1,Start,On,10,14,MAX...
2,,On,8439,0,MAX...
