To me the interface of the power supply itself is quite good, so I didn't see the need to invest in the software. The logging is very useful to me and I used to capture battery charge curves. I don't recall averaging being implemented in the supply. It can save all data in .csv format to a pendrive, so Excel or other spreadsheet software can manipulate data quite nicely. The sample interval goes from 200ms to 60s and the supply nicely calculates the time duration depending on the sample interval, the different collection of logged information per channel (P, V, A) and the memory available. |

I guess measurements/log performed right on the instrument are more accurate (in time/timestamps) than reading back through lan/pyvisa etc. since they avoid the command overhead and jitter. Although 200ms is not too fast. Have you found this restrictive? |
| rsjsouza:
It is restrictive if I want to log fast current transients, but for that I have an oscilloscope. I simply live with the fact this is a pretty good power supply with a built-in 5Hz DSO - plenty for what I use. |

Hi, is the (transformer?) hum normal? It appears as soon as the device gets plugged in. |
