Dunno what to suggest then for a display upgrade/hack. :-// |

Simply open the S version .ugf file in a hex editor (or maybe notepad) and change the 'SPD3303S' header to 'SPD3303D'. (EDIT: Ooops, I had that the other way around... :-//) --- End quote --- does this really work? Any1 tried and gives the 0.000A accuracy ? And where do I get the S firmware. I was only able to find the D FW. thanks :) |

I couldnt find the firmwares for SPD3303D/SPD3303S anywhere live but archive.org does have them https://web.archive.org/web/20150908094808/http://www.siglentamerica.com/prodcut-gjjrj.aspx?id=175&tid=17&T=2 Just tried the hex edit and successfully flashed the S version of 1.01.01.01.06R2 over the 1.01.01.01.06R1 on an SPD3303D. Extra digits are there now 🥳, but haven't tested much. |

I have an old SPD3303D power supply, which is discontinued but in excellent condition. Firmware version 1.01.01.06R2. "upgraded" to SPD3303S . It has a minor voltage issue on the first channel. Has anyone managed to calibrate the SPD3303D/S? I am using the NI VISA Test Panel and PYVISA lib with the SPD3303X calibration guide https://www.eevblog.com/forum/testgear/siglent-sds3303x(-e)-calibration-fw1-01-01-02-07r2-best-practice/ with no success. The issue is that after executing the commands "*CALCLS 0" and "*CALCLS 1" correctly, the command "CALibration:VOLTage CH1,1,0.8736" is not accepted, and the power supply beeps. I tried downgrading to SPD3303D, changing the number of decimal places, removing and adding different line-ending characters, but without success. I also tried downgrading the firmware to the only one I found, 1.01.01.03R1, but also without success. The device doesn’t want to update through EasyPower. Has anyone had a successful calibration of such a power supply? |
