Hi,
I have a Siglent SDS 1052DL oscilloscope. It looks good, works.. almost good.
The problem is strage values of voltage measurmets depend on a set scale:
10V scale:
5V scale:
2V scale:
1V scale:
500mV scale:
and 200mV scale (which is very ...ech. strange):
A circuit: simple voltage divider, power supply stable 5V. Out voltage of the divider 1.552V measured by meter.
At 500mV scale the measurement is similar to indications of the meter, but other values are rounded.
I've made a test with 12V on second channel, and with a large scale (I do not remember the value), oscilloscope shown me 18Volts!.
My question is, if it is normal for that kind of equipment, or maybe this Sglent is a crap?
Best regards
Edgarus.
