DSO firmware version 3.43

In firmware versions prior to V3.4, a pull-up resistor was (incorrectly) active on V2 hardware ADC input and so would limit floating noise. Re-enabling this pull-up however is not a good option, because the pull-up resistance interacts with source input. For a low impedance load this is less of an issue, but for moderate to high impedance loads, this may cause highly inaccurate measurements.

Ben,
if I understand this right, you did consider both ADC’s (regarding the parallel connected input pins) - correct?
