Siglent SPD4121X software
Remote control and data logging for the Siglent SPD4121X power supply, on Windows, Linux and macOS - with the same panel BenchMesh uses for every power supply.
Status
Very likely. Support for the Siglent SPD4121X 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 SPD4121X yet. If you own one, connecting it once and reporting the result moves it to Community-confirmed.

- Over USB-TMC or LAN (SCPI socket). USB Test & Measurement Class (USB id f4ec). No vendor driver needed on Linux; on Windows BenchMesh installs Microsoft’s WinUSB driver with one click. Then press Detect in BenchMesh: it identifies the power supply by its reply and adds it to the bench.
- What can I control on the SPD4121X?
- Power supply: set current, current limit, ocp, output, remote, voltage, voltage limit; read cc, cv, fail, iout, ocp, output, ovp, pout.
- Can I log SPD4121X measurements to CSV?
- Yes. Right-click any reading to add it to a recording; every instrument on the bench is sampled on one shared timeline and exported as one CSV.
