DISPlay Subsystem
The DISPlay group of commands is used to control the selection and presentation of textual, graphical and TRACe measurements.
DISPlay:CLEar
Description:
Clear display traces and all data buffers. Clears averaging filters to empty. Does NOT clear errors.
Syntax:
DISPlay:CLEar
Argument:
None Valid Modes: All
 
DISPlay:ENVELOPE[:STATe]
Description:
Enable or disable the Envelope mode. Syntax: DISPlay:ENVELOPE <Boolean> Argument: <Boolean> = { 0, 1, ON, OFF }
Valid Modes:
Pulse and Modulated
 
DISPlay:MODUlated:TIMEBASE
Description:
Set or return the Modulated Mode timebase in seconds/division. The ML2439A has fixed timebase settings in a 1-2-5 sequence. If the argument does not match one of these settings, it will be forced to the next highest entry.
Optional units:
minutes.
Syntax:
DISPlay:MODUlated:TIMEBASE <numeric_value>
Argument:
<numeric_value> = 10e-9 to 10 s, (1-2-5 sequence), 30 s, 1, 2, 5, 10, 30, 60 min
Valid Modes:
Modulated Mode
Note: There are separate time bases for the modulated mode and the pulse mode. The arguments selected are saved and restored independently by mode.
 
DISPlay:MODUlated:TSPAN
Description:
Set or return the horizontal time span of the display in modulated mode. Time span = 10* Time/Division.
Optional units:
minutes.
Syntax:
DISPlay:MODUlated:TSPAN <numeric_value>
Argument:
<numeric_value> = 100e-9 to 100 s in a 1-2-5 sequence, 300 s, 10, 20, 50, 100, 300, 600 min
Valid Modes:
Modulated mode
 
DISPlay:PULSe:TIMEBASE
Description:
Set or return the Pulse Mode timebase in seconds/division. The ML2439A has fixed timebase settings in a 1-2-5 sequence. If the argument does not match one of these settings, it will be forced to the next highest entry.
Optional units:
minutes.
Syntax:
DISPlay:PULSe:TIMEBASE <numeric_value>
Argument:
<numeric_value> = 5e-9 to 50e-3, (1-2-5 sequence) 60 min Valid Modes: Pulse Mode
Note: There are separate time bases for the modulated mode and the pulse mode. The arguments selected are saved and restored independently by mode.
 
DISPlay:PULSe:TSPAN
Description:
Set or return the horizontal time span of the display in pulse mode. Time span = 10* Time/Division.
Optional units:
minutes.
Syntax:
DISPlay:PULSe:TSPAN <numeric_value>
Argument:
<numeric_value>= 50e-9 to 500e-3 in a 1-2-5 sequence, 600 min
Valid Modes:
Pulse mode
Note There are separate time bases for the modulated mode and the pulse mode. The arguments selected are saved and restored independently by mode.
 
DISPlay:[TEXt:]LIN:RESolution
Description:
Set or return the display resolution for linear power and voltage readings. The number of significant digits displayed is equal to the argument. This command also sets the resolution of measurements returned in remote mode.
Syntax:
DISPlay:[TEXt:]LIN:RESolution <numeric_value>
Argument:
<numeric_value> = 3 to 5
Valid Modes:
All
 
DISPlay:[TEXt:]LOG:RESolution
Description:
Set or return the display resolution for logarithmic power and voltage readings. The number of decimal places displayed is equal to the argument. This command also sets the resolution of measurements returned in remote mode.
Syntax:
DISPlay:[TEXt:]LOG:RESolution <numeric_value>
Argument:
<numeric_value> = 0 to 3
Valid Modes:
All
 
DISPlay:TRACe:HOFFSet
Description:
Set or return the statistical mode horizontal scale offset in dB. The offset value will appear at the leftmost edge of the scale with units dBr (decibels relative).
Syntax:
DISPlay:TRACe[1|2|3|4]:HOFFSet <numeric_value>
Argument:
<numeric_value> = -50.00 to +50.00
Valid Modes:
Statistical
 
DISPlay:TRACe:HSCALe
Description:
Set or return the statistical mode horizontal scale in dB/Div.
Syntax:
DISPlay:TRACe[1|2|3|4]:HSCALe <numeric_value>
Argument:
<numeric_value> = 0.1 to 5.0 in a 1-2-5 sequence Valid Modes: Statistical
 
DISPlay:TRACe:VCENTer
Description:
Set or return the power or voltage level of the horizontal centerline of the graph for the specified channel in channel units. If a change in the vertical scale causes the center maximum value to be exceeded, the center will be forced to the maximum value for the new range.
Syntax:
DISPlay:TRACe[1|2|3|4]:VCENTer <numeric_value>
Argument:
<numeric_value> =
–200.00 to +200.00 for dBm units
± 10,000 times the vertical scale power/div for watts units
± 10,000 times the vertical scale volts/div for volts units
Valid Modes:
All
 
DISPlay:TRACe:VSCALe
Description:
Set or return the power or voltage vertical sensitivity of the trace display in channel units.
Syntax:
DISPlay:TRACe[1|2|3|4]:VSCALe <numeric_value>
Argument:
Units = dBm, dBV, dBmV, dBuV , <numeric_value> = range in dB/division
Units = watts <numeric_value> = range in watts/division
Units = volts <numeric_value> = range in volts/division
Valid Modes:
