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).

Arguments
<NR3> is a floating point number that specifies the position value for channel <x>,
in divisions, from the center graticule. The range is 8 to -8 divisions.
Examples
CH2:POSition 1.3 positions the Channel 2 input signal 1.3 divisions above the
center graticule.
CH1:POSition? might return : CH1:POSITION -1.3000 indicating that the
current position of Channel 1 is 1.3 divisions below the center graticule.
CH<x>:PRObe? (Query Only)
Returns all information concerning the probe attached to channel <x>, where x
is the channel number.

CH<x>:PRObe:AUTOZero (No Query Form)
This command executes the attached probe’s Auto Zero function, for probes that
support this feature. See your probe documentation for more details.

CH<x>:PRObe:CALibrate (No Query Form)
This command executes a calibration or initialization for the probe attached to
channel 1–4,
if the probe is calibratable. To determine whether the probe is
calibratable, use CH<x>:PRObe:CALibrate:CALIBRATABLe?. The channel is
specified by x, which can range from 1 through 4.

CH<x>:PRObe:CALibrate:CALIBRATABLe? (Query Only)
This query returns the state of the probe attached to channel 1–4, either 0 ifthe
probe is not calibratable, or 1 if the probe is calibratable. The channel is specified
by x, which can range from 1 through 4.

might return 0, indicating that the
probe attached to channel 2 is not calibratable.
CH<x>:PRObe:CALibrate:STATE? (Query Only)
This query returns the calibration state of the probe connected to the specified
channel. If the probe is calibratable, the state could be either DEFAULT (not
calibrated), COMPensated, or RUNNING (calibration is proceeding). If theprobe
is not cali
bratable, DEFAULT will be returned. The channel is specified by x,
which can range from 1 through 4.

CH<x>:PRObe:CALibrate:STATE?
Related Commands
CH<x>:PRObe:CALibrate
CH<x>:PRObe:CALibrate:CALIBRATABLe?
Returns
DEFAULT — not calibrated.
COMPensated — last calibration passed.
RUNNING — probe calibration is in progress.
Examples
CH2:PRObe:CALibrate:STATE? might return DEFAULT, indicating that the
probe is not calibrated.
CH<x>:PRObe:COMMAND (No Query Form)
Sets the state of the probe control specified with the first argument to the state
specified with the second argument. The commands and states are unique to the
attached probe. Only certain VPI prob
es support this command. See the specific
probe documentation for how to set these string arguments.
The command form takes 2 string argum
ents: the first is the probe command
enumeration and the second is the data value.
The query form requires a single qu
oted string argument to specify the probe
command enumeration for which the response data is requested.
