I experience a problem when I use the 500mV range on all 2203, 2204 and 2205 scopes.
The values are strangely scaled by a factor x400. E.g. if the actual peak voltage is 300mV (this what the +/-1V range returns as well), then the value the 500mV range returns is 120. This is consistent with all three instruments and only for this range, all >1V ones return the actual magnitude.
I couldn't find any relevant information in the programmer's guide. Is there something specific to the mV scales?
Thanks in advance,
