FSW-K40
120User Manual 1173.9286.02 ─ 15
Parameters:
<HalfDecade> Start offset frequency of the half decade you want to display.
Note that the half decade you want to display has to be part of
the current measurement range.
Range: 100 mHz...300 mHz to 3 GHz...10GHz
*RST: Half decade display is off.
Example:
DISP:TRAC:X:HDEC 1KHZ
Displays the half decade beginning with 1 kHz.
Manual operation: See "Half Decade" on page 52
DISPlay[:WINDow]:TRACe:X[:SCALe]:SCOPe <Scope>
This command selects the way the application scales the horizontal axis.
Parameters:
<Scope> HDECade
Shows a particular half decade only.
You can select a particular half decade with .
MANual
Shows a custom part of the measurement range.
You can select the start and stop offsets with .
MRANGe
Shows the complete measurement range.
*RST: MRANGe
Example:
DISP:TRAC:X:SCOP MRAN
Shows the complete measurement range on the x-axis.
Manual operation: See "X-Axis Scope" on page 51
DISPlay[:WINDow]:TRACe:X[:SCALe]:STARt <StartFrequency>
This command selects the start frequency of the display range.
Before you can use the command you have to select a manual display range for the x-
axis with DISPlay[:WINDow]:TRACe:X[:SCALe]:SCOPe.
Parameters:
<StartFrequency> Start offset frequency of a half decade.
Note that the start offset you want to display has to be part of the
current measurement range.
Range: 100 mHz to 3 GHz
*RST: Manual display range is OFF
Example:
DISP:TRAC:X:STAR 100HZ
Defines 100 Hz as the start of the display range.
Manual operation: See "X-Axis Start / Stop" on page 52
