RF:PRObe:CAL
ibrate:STATE? (Query Only)
This command returns the calibration state of the probe connected to the RF input.
Conditions
MDO3000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.
Group
RF
Syntax
RF:PRObe:CALibrate:STATE?
Returns
DEFAULT — Not calibrated
COMPensated — Last calibration passed
RUNNING — Probe calibration is in progress.
Examples
RF:PRObe:CALibrate:STATE? might return DEFAULT, indicating that the
probe is not calibrated.
RF:PRObe:COMMAND
This command 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 type. See the probe documentation for how to set
these string arguments.
The command form takes 2 string arguments: the first is the probe command
enumeration and the second is the data value.
The query form requires a single quoted string argument to specify the probe
command enumeration for which the response data is requested.
Conditions
MDO3000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.
Group
RF
Syntax
RF:PRObe:COMMAND <QString>, <QStrin g>
RF:PRObe:COMMAND? <QString>
Arguments
<QString> are quoted strings specifying the probe command and value to set in
the probe attached to the specified channel.

Commands Listed in Alphabetical Order
Examples
RF:PROBE:COMM
AND “MODE ”, “4–4V1MHz ”
sets a Tektronix VPI-DPG probe
to the 4-4V1MHz mode.
RF:PROBE:COM
MAND “O UTPUT”, “ON”
turns the output of a Tektronix
VPI-DPG probe on.
RF:PROBE:C
OMMAND?“MODE”
might return RF:PROBE:COMMAND
“MODE”,“4-4V1MHZ”
.
RF:PRObe:DEGAUss (No Query Form)
This command starts a degauss/AutoZero cycle on a TekVPI current probe
attached to the RF input.
Conditions
MDO3000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.
Group
RF
Syntax
RF:PRObe:DEGAUss EXECute
Examples
RF:PROBE:DEGAUSS EXECute begins the degauss/AutoZero operation.
RF:PRObe:DEGAUss:STATE? (Query Only)
This command returns the state of the probe degauss for the RF input.
NOTE. This command will return
PASSED
for probes that do not support degauss
operations.
Conditions
MDO3000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.
Group
RF
Syntax
RF:PRObe:DEGAUss:STATE?
Returns
NEEDED indicates the probe should be degaussed before taking measurements.
RECOMMENDED indicates the measurement accuracy might be improved by
degaussing the probe.

FAILED indicates the degauss operation failed.
RUNNING indicates the probe degauss operation is currently in progress.
Examples
RF:PROBE:DEGAUSS:STATE? might return FAILED, indicating the degauss
operation failed.
RF:PRObe:FORCEDRange
This command specifies the range of a TekVPI probe attached to the RF input.
Conditions
MDO3
000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.
Group
RF
Syntax
RF:PRObe:FORCEDRange <NR3>
RF: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.
RF:PRObe:GAIN
This command specifies the scale factor for the probe attached to the RF input.
Conditions
MDO3000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.
Group
RF
Syntax
RF:PRObe:GAIN <NR3>
RF:PRObe:GAIN?
Arguments
<NR3> is a floating point number that specifies the probe scale factor. Allowed
