In the V1.5 firmware, Siglent added the ability to read/write measurement types used by Power Analysis, including:
- PFACtor Power Factor
- RPOWer Real Power
- APOWer Apparent Power
- RPOWer Reactive Power
- PANGle Phase Angle
Bug report: They use RPOWer for both Real Power and Reactive Power. As a result, you can't specify Reactive Power via SCPI.
Additionally, the above measurements are **** until you turn on Power Analysis, and there's no way to control Power Analysis via SCPI. I think all of the other options can be controlled by SCPI, so this seems like an omission.
Feature request: Add SCPI commands to control Power Analysis, at least to turn it on. That way I could configure the scope to display power measurements entirely via SCPI.
For now I can simply script VNC to click on the right spots ("Analysis" then "Power Analysis" then "Test State" on), but it would also be nice if it wouldn't reset everything when I do.
Nice to have: Ideally there would be UI for configuring measurement display of power analysis rather than just SCPI. (For example, a "Power" tab in the "Measure select" window could let you select Power Analysis measurements.)
Nice to have: It would also be nice to have RMS() be an available math function in the function editor. Right now I can define F1=C1*C2 and display RMS(F1), but real power is RMS(C1)*RMS(C2).
