Examples
RF:MEASUre:TY
Pe ACPR
sets the RF measurement type to ACPR.
RF:MEASUre:TYPe? might return NONE, the default.
RF:POSition
This command specifies the vertical position for the frequency domain traces. The
vertical position is the location of the Reference Level with respect to thetop
of the graticule, in divisions. The lower limit is –10 divisions. The upper limit
is +10 divisions.
Conditions
MDO3000, MDO4000/B, or MDO4000C model
s with option SA3 or SA6 only.
Group
RF
Syntax
RF:POSition <NR3>
RF:POSition?
Related Commands
RF:UNIts
Arguments
<NR3> is a floating point number.
Examples
RF:POSITION –3 moves the frequen
cy domain baseline indicator down3 graticule
divisions from its default position.
RF:POSITION? might return 3.0
000, indicating the baseline indicator has been
set 3 divisions up from its default position.
RF:PRObe:AUTOZero (No Query Form)
This command executes the attached probe’s AutoZero function, for probes that
support this feature. See your probe documentation for more details.
Conditions
MDO3000, MDO4000/B, or MDO4000C models with option S
A3 or SA6 only.

RF:PROBE:AUTO
ZERO EXECute
performs the AutoZero function in the probe.
RF:PRObe:CALibrate (No Query Form)
This command executes a calibration or initialization for a probe attachedto
the RF input,
if the probe is calibratable. To determine whether the probe is
calibratable, use RF:PRObe:CALibrate:CALIBRATABLe?.
Conditions
MDO3000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.

Arguments
EXECute — executes a calibration for the attached probe.
INITialize — initializes the attached probe.
Examples
RF:PROBE:CALIBRATE INIT initializes the probe attached to the RF input.
RF:PRObe:CALibrate:CALIBRATABLe? (Query Only)
This query returns a boolean value that indicates whether the attached probe is
calibratable.
Conditions

Syntax
RF:PRObe:CALibrate:CALIBRATABLe?
Examples
RF:PRObe:CALibrate:CALIBRATABLe? might return 0, indicating that the
probe attached to the RF input is not calibratable.

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.

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.

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.
