DC Coupling Dynamic Range

Postby franceconve » Mon Jun 08, 2009 8:31 pm

I'm using a 2205 oscilloscope to analize analog signals in the range of 0-3V. I've notice that there is no way to waste half of dymamic range of the oscilloscope A/D converter. Infact if I use the +/-2V range I see the overange indication.
Is there any way to adjust the offset and maintain full dynamic range (i.e. subctracting a DC component)?

The 2205 has nine input ranges, from ±50 mV to ±20 V. It is not possible to change these.

You can try using resolution enhancement to reduce the effect of quantisation in the waveform.
