:SENSe:RFLection:REFerence:UNIT
:SENSe:RFLection:REFerence:VSWR
:SENSe:RFLection:REFerence:RFACtor
:SENSe:RFLection:REFerence:RPOWer
Syntax
:SENSe:RFLection:REFerence:UNIT <PredefExpr>
Parameters
PredefExpr is one of the following predefined expressions: RETurn-
loss|VSWR|RFACtor|RPOWer
.
Default is RETurnloss.
Command
Switches the display to following units: return loss (dB), VSWR (-), reflection
factor (mRho) or reflected power (%).
Query
Reads and returns the current setting.
Example
:SENSe:RFLection:REFerence:UNIT DBM
:SENSe:RFLection:REFerence:UNIT?
Returns the following string: "DBM"
Syntax
:SENSe:RFLection:REFerence:VSWR <real1>
Parameters
real1 is a floating point real number.
The minimum value for real1
is 1.0. The maximum value for real1 is
1000.0. The default value for real1 is 10.0.
Command
This command sets the maximum VSWR value for reflection display when
the unit is set to VSWR.
Query
Reads and returns the current setting.
Example
:SENSe:RFLection:REFerence:VSWR 500
:SENSe:RFLection:REFerence:VSWR?
The value returned in this example is: "500.0"
.
Syntax
:SENSe:RFLection:REFerence:RFACtor <real1>
Parameters
real1 is a floating point real number.
The minimum value for real1 is 0 mRho
. The maximum value for real1 is
2000 mRho
. The default value for real1 is 2000 mRho.
Command
This command sets the maximum factor value for reflection display when
the unit is set to reflection factor.
Query
Reads and returns the current setting.
Example
:SENSe:RFLection:REFerence:RFACtor 1000
:SENSe:RFLection:REFerence:RFACtor?
The value returned in this example is: "1000.0"
.
Syntax
:SENSe:RFLection:REFerence:RPOWer <real1>
Parameters
real1 is a floating point real number.
The minimum value for real1 is 0.0 %
. The maximum value for real1 is
200.0 %
. The default value for real1 is 200.0 %.
Command
This command sets the maximum power value for reflection display when
the unit is set to reflected power.
