## Questions & Answers

**Q: What are the actual dimensions of the power supply?**
A: Dimensions of the Siglent SPD3303C - from our website:
275×225×136 mm

**Q: I want to control this from my own windows program.  does it enumerate as a com port that i can send and receive text commands? i don't use labview.**
A: Yes, and it takes standard SCPI commands. Works great for this, I’ve been controlling mine with Python/PySerial.

**Q: Can the outputs be connected in series to produce higher voltages?**
A: Yes, in series mode, it can output 60 volts, but not 64 v as you might expect, which would be twice the 32 v that it outputs in independent or parallel mode.  I don't know why it limits to 60 volts in series mode, but it will output 60 v at 3.2 amps

**Q: Can this bench power supply negative voltages?**
A: The SPD3303C is an FLOATING unipolar power supply - like a battery.   The red terminal is always more positive than the black terminal.
