Examples
CH2:PRObe:CAL
ibrate:CALIBRATABLe?
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.

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.

Commands Listed in Alphabetical Order
Syntax
CH<x>:PRObe:C
OMMAND <Q String>, <QString>
Arguments
<QString> are quoted strings specifying the probe command and value to set in
the probe attached to the specified channel.
Examples
CH1:PROBE:COMMAND “MODE”, “4–4V1MH z” sets a Tektronix VPI-DPG probe
to the 4-4V1MHz mode.
CH1:PROBE:COMMAND “OUTPUT”, “ON” turns the output of a Tektronix
VPI-DPG probe on.
CH1:PROBE:COMMAND?“MODE” might return CH1:PROBE:COMMAND
“MODE”,“4-4V1MHZ”
.
CH<x>:PRObe:DEGAUss (No Query Form)
This command starts a degauss auto-zero cycle on a TekVPI current probe
attached to the input channel specified by <x>, where x is the channel number.

Syntax
CH<x>:PRObe:DEGAUss EXECute
Arguments
EXECute initiates the degauss operation.
CH<x>:PRObe:DEGAUss:STATE? (Query Only)
This command returns the state of the probe degauss for the channel specifiedby
<x>, where is x is the channel number.
NOTE. This command will return
PASSED
for probes that do not support degauss
operations.

CH<x>:PRObe:DEGAUss:STATE?
Returns
NEEDED indicates the prob
e should be degaussed before taking measurements.

RECOMMENDED in
dicates the measurement accuracy might be improved by
degaussing the probe.
PASSED indica
tes the probe is degaussed.
FAILED indicates the degauss operation failed.
RUNNING indicates the probe degauss operation is currently in progress.
CH<x>:PRObe:FORCEDRange
This comma
nd specifies the range of a TekVPI probe attached to the channel
specified by <x>, where x is the channel number.
NOTE. This command will return
PASSED
for probes that do not support degauss
operations.

Syntax
CH<x>:PRObe:FORCEDRange <NR3>
CH<x>:PRObe:FORCEDRange?
Arguments
<NR3> is a floating point number that specifies the range, which is probe specific.
Returns
The query form of this command returns 0.0 for probes that do not support
forced ranges.
CH<x>:PRObe:GAIN
This command specifies the gain factor for the probe attached to the channel
specified by <x>, where x is the channel number. The "gain" of a probe is the
output divided by the input transfer ratio. For example, a common 10x probe
has a gain of 1V.
