Display commands
The display command subsystem affects the screen of the instrument.
:DISPlay:TRACe:Y[:SCALe][:LOGarithmic]
:DISPlay:TRACe:Y[:SCALe]:LINear:VOLT
:DISPlay:TRACe:Y[:SCALe]:LINear:WATT
Syntax
:DISPlay:TRACe:Y[:SCALe][:LOGarithmic] <int1>
Parameters
int1 is an integer. The minimum value for <int1> is 1, the maximum is
20
. Valid values are 1, 2, 5, 10, 20. The default value is 10.
Command
Holds the upper limit of the power scale but changes the resolution (and
the lower limit) of the scale when int1 defines how many dB per scale unit
are shown on the display.
Query
Returns the current setting.
Example
:DISPlay:TRACe:Y[:SCALe][:LOGarithmic] 20
:DISPlay:TRACe:Y[:SCALe][:LOGarithmic]?
The value returned in this example is: "20"
.
Syntax
:DISPlay:TRACe:Y[:SCALe]:LINear:VOLT <real1>
Parameters
real1 is a floating point real number.
The minimum value for real1 is 0.00001
. The maximum value for real1
is 1.0
. The default value for real1 is 0.001.
Command
This command is only in effect when 9102 is set to voltage unit. It holds the
upper limit of the scale but changes the resolution (and the lower limit) of
the voltage scale. real1 defines how many volts per scale unit are shown
on the display. The resolution depends on which unit is set with
SENSe:REFLevel:UNIT. If it set to V the command and query is in Volts.
If it set to MV the command and query is in Milli Volts. If it set to UV the
command and query is in Micro Volts.
Query
Returns the current setting.
Example
:DISPlay:TRACe:Y[:SCALe]:LINear:VOLT 0.0005
:DISPlay:TRACe:Y:[SCALe]:LINear:VOLT?
The value returned in this example is: "0.0005"
.
Syntax
:DISPlay:TRACe:Y[:SCALe]:LINear:WATT <real1>
Parameters
real1 is a floating point real number.
The minimum value for real1
is 0.00000000001. The maximum value for
real1
is 0.1. The default value for real1 is 0.000001.
Command
This command is only in effect when 9102 is set to Watt unit. It holds the
upper limit of the scale but changes the resolution (and the lower limit) of
the Watt scale. real1 defines how many Watts per scale unit are shown on
the display. The resolution depends on which unit is set with
SENSe:REFLevel:UNIT. If it set to MW the command and query is in Milli
Watts. If it set to UW the command and query is in Micro Watts.
Query
Returns the current setting.
