Siglent SPD3303C software
Remote control and data logging for the Siglent SPD3303C power supply, on Windows, Linux and macOS - with the same panel BenchMesh uses for every power supply.
Status
Very likely. Support for the Siglent SPD3303C was written from Siglent’s programming manual and follows the same engine as the bench-tested instruments, but nobody has confirmed it on a real SPD3303C yet. If you own one, connecting it once and reporting the result moves it to Community-confirmed.
Note: USB only; no MEAS:POWE? (power is V*I)
