DISPlay[:WINDow]:TRACe:X[:SCALe]:STOP <StopFrequency>
This command selects the stop 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:
<StopFrequency> Stop offset frequency of a half decade.
Note that the stop offset you want to display has to be part of the
current measurement range.
Range: 300 mHz to 10 GHz
*RST: Manual display range is OFF
Example:
DISP:TRAC:X:STOP 3KHZ
Defines 3 kHz as the end of the display range.
Manual operation: See "X-Axis Start / Stop" on page 52
DISPlay[:WINDow]:TRACe:Y:[:SCALe] <Range>
This command defines the display range.
Note that you have to select manual y-axis scaling before you can use the command.
Parameters:
<Range> Range: 1 to 200
*RST: 100
Default unit: dB
Example:
DISP:TRAC:Y 80
Defines a display range over 80 dB.
Manual operation: See "Top / Range / Bottom" on page 52
DISPlay[:WINDow]:TRACe:Y[:SCALe]:AUTO <Mode>
This command turns automatic scaling of the vertical axis on and off.
Parameters:
<Mode> ON
Automatic scaling is on.
OFF
Automatic scaling is off.
ONCE
Automatic scaling is performed once, then turned off again.
*RST: ON
Example:
DISP:WIND2:TRAC:Y:SCAL:AUTO ONCE
Scales the vertical axis once.
Manual operation: See "Y Axis Scaling" on page 52
