CH<x>:IMPedance

Sets or returns the channel probe impedance.

Vertical

CH<x>:IMPedance { FIFty | MEG }

CH<x>:IMPedance?

<x> specifies the input channel. Valid values are 1, 2, 3, and 4.

FIFty sets the specified channel to 50 Ω impedance.

MEG sets the specified channel to 1 MΩ impedance.

CH1:IMPEDANCE?

might return MEG.

CH<x>:INVert

Sets or returns the specified channel signal invert setting. This command is

equivalent to setting Invert in the Vertical menu.

Vertical

CH<x>:INVert { <NR1> | ON | OFF }

CH<x>:INVert?

<x> specifies the input channel. Valid values are 1, 2, 3, and 4.

<NR1> = 0 or OFF sets the channel to invert off (normal display).

<NR1> = 1 or ON sets the channel to invert on.

CH<x>:INVERT?

might return 0, indicating that channel 1 is not inverted.
