3. Push DC, AC,orGND (ground).
UseDCcouplingtopassbothACandDC
components.
DC
Use AC coupling to block the DC component
and show only the AC signal.
AC
Use Ground (GND) to display the reference
potential.
GND
4. Push Ω.
Ω
1M 50
Set the input impeda nce (termination) to 50 Ω
or 1 MΩ if using DC or Gnd coupling. Input
impedance is automatically set to 1 MΩ when
using AC coupling.
For more information on input impedance, see
Quick Tips below.
