N/A

For 50 Ω input, 1 V/div is the maximum setting.

NOTE. The above table describes oscilloscope behavior only when no probe is

attached, and when the external attenuation factor is 1.0.

CH<x>:POSition

Arguments

<NR3> is the offset value for the speciﬁed channel <x>.

Examples

CH3:OFFSet 2.0E-3 sets the offset for channel 3 to 2 mV.

CH4:OFFSet? might return :CH4:OFFSET 1.0000E-03 indicating that the

offset for channel 4 is set to 1 mV.

CH<x>:POSition

Sets or returns the vertical position of channel <x>, where x is the channel

number. The position value is applied to the signal before it is digitized.

Increasing the position value of a waveform causes the waveform to move up.

Decreasing the position value causes t he waveform to move down. The position

value determines the vertical graticule coordinate at which input s ignal values,

minus the present o ffset setting for that chan

nel, are displayed. For example,

if the position for Channel 3 is set to 2.0 and the offset is set to 3.0, then input

signals equal to 3.0 units are displayed 2.0 divisions above the center of the screen

(at 1 V/div).
