Note 1: BNC with Probe Readout pin which causes the instrument to change V/div
indication, input impedance, and attenuator setting according to the probe
(when equiped with a probe indicator).
Note 2: Measured up to 200 MHz input frequency; in dc and ac coupling of input.

See Note 1
Note 1: In GND position: channel disconnected from input, and connected to
ground, BNC open (when not in 50
Ω
position). The GND coupling is
available for all channels except EXTTRIG.
