Command Descriptions
CH<x>:POSiti
on
Sets or queries the vertical position of the specified oscilloscope channel. The
value of <x> can vary from 1 through 4 for 4-channel instruments or 1 through
2 for 2-chann
el instruments.
The position voltage value is applied to the signal before digitization. This
command is e

Examples
CH2:POSITION 1.32E0 positions the channel 2 input signal 1.32 divisions
above the center of the display.
CH1:POSITION? might return -1.32E0, indicating that the current position of
channel 1 is at -1.32 divisions.
CH<x>:PRObe
Sets or queries the attenuation factor of the specified channel or voltage probes.
The value of <x> can vary from 1 through 4 for 4-channel instruments or 1
through 2 for 2-channel instruments.
