Hi!
I'm about to buy my first scope. And it's gonna be DS1054Z probably. I just want to know if it's possible to measure/get characteristic of slow processes like charging and discharging batteries for instance. Automatically of course (kind of time-lapse during few hours). Is that possible?
Thx
Other people answered the question "Is it a very good way to measure slow processes ... with a DS1054z?" The answer to that question is probably no, but it is certainly possible.
The experimental setup:
- 12V sealed lead acid battery (UPS battery)
- DPS5005 (buck) power supply
- 25W constant current load
- Rigol 1054z
The settings:
- The load was set to draw 12.00 watts.
- CH1 is watching the voltage of the battery, DC coupled, 2.00V/div
- CH2 is watching the voltage of the battery, AC coupled, 50.0mV/div (to watch the noise fed back to the battery from the DPS5005)
- I am using the Rigol Bildschirmkopie software to take a screen capture every 10 seconds over USB
- I discard 5/6 screen captures to make the displayed GIF
If, for some reason, you want to watch the GIF made from every data point (~ 15 MB),
.
You probably want to collect data rather than screen captures, but I made this to show that you it's certainly possible and it's already useful even in this sort of dreadful setup.
For instance, we can see that as the battery drains more (and therefore the DC-DC converters V_input gets closer to its V_output, which was about 7 volts or so), its noise increases (or certainly changes shape).
