CALCulate:PNLimit:FC3 is available for special phase noise limit lines with three seg-
ment or more.
CALCulate:PNLimit:FC4 is available for special phase noise limit lines with four seg-
ment or more.
CALCulate:PNLimit:FC5 is available for special phase noise limit lines with five seg-
ments.
Parameters:
<Frequency> Offset frequency relative to the carrier frequency.
The minimum offset is 1 Hz. The maximum offset depends on
the hardware you are using.
*RST: 1 MHz
Example:
CALC:PNL:FC1 2MHZ
Defines a corner frequency at 2 MHz offset.
Manual operation: See "Range x - Range y" on page 59
CALCulate:PNLimit:NOISe <NoiseLevel>
This command defines the noise floor level of the DUT.
The noise floor level is necessary for the calculation of a phase noise limit line.
Parameters:
<NoiseLevel> Range: -200 to 200
*RST: 0
Default unit: dBm/Hz
Example:
CALC:PNL:NOIS -150
Defines a noise floor level of 150 dBm/Hz.
Manual operation: See "Noise Floor" on page 59
CALCulate:PNLimit:TRACe <Trace>
This command selects the trace to assign a phase noise limit line to.
Parameters:
<Trace> Range: 1 to 6
*RST: -
Example:
CALC:PNL:TRAC 1
Assigns the phase noise limit line to trace 1.
Manual operation: See "Selected Traces" on page 59
CALCulate:PNLimit:TYPE <Shape>
This command selects the shape of a phase noise limit line.
