DPO3032 - Offset Issue - Tektronix and Keithley If I switch from a generic probe (non-Tektronix) to a P6139A probe the offset goes away If there are no probes connected the offset is still there but only in the 1M-ohm setting The Offset is present in both DC and AC coupling (with non-Tektronix probe and no probe) Is there a probe impedence requirement for this scope?
