Reading Rigol DP800 Record (*.ROF) Files with Excel
Date: 07.17.2015
Solution: The Rigol DP800 series of power supplies have the option to data log the
output voltage and current using the Record feature.
This application note covers how to convert the binary file format native to the
record file type (*ROF) to decimal using HxD (A hex-to-decimal software
package) and the ReadDPROF file, a worksheet created using Microsoft Excel
2010.
The end of this document describes the format of the data in the *ROF file and the
Excel functions that were used to convert each data point to decimal.
Steps:
1) Configure the DP800 outputs and Devices (DUTs) for your experiment
2) Insert a USB stick (FAT32 format) into the USB slot on the back panel of
the instrument
