Hi all,
I'm playing around and testing with my new DS2072A scope.
Someone other than me, has noticed different sensibility to noise and mechanical vibration between CH1 and CH2?
I found out by trying to connect two 50 Ohm terminator to the inputs.
CH1 got some spikes with terminator attached, CH2 near-no difference.
(500uV/div)
Without terminators:
With terminators:
Another strange behaviour I've noticed is a big difference in sensibility to mechanical vibration between CH1 and CH2.
Tapping front panel:
Closing top handle:
Not a big issue, but strange, not?
I've also noticed a slight positive DC offset (about 0.2div) on CH1, even after auto-cal run.
Bye,
Edoardo
