Phase Noise Limit Line
Selects the shape of the phase noise limit line.
For more information see Chapter 4.9, "Using Limit Lines" , on page 31.
"None" No limit line.
"Noise floor
and x Ranges" Limit line defined by the noise floor and x corner frequencies and
slopes. The application supports up to 5 ranges.
Remote command:
CALCulate:PNLimit:TYPE
on page 107
Selected Traces
Selects the trace(s) to assign a phase noise limit line to.
For more information see Chapter 4.9, "Using Limit Lines" , on page 31.
Remote command:
CALCulate:PNLimit:TRACe
on page 107
Noise Floor
Defines the noise floor level in dBm/Hz of the DUT.
For more information see Chapter 4.9, "Using Limit Lines" , on page 31.
Remote command:
CALCulate:PNLimit:NOISe
on page 107
Range x - Range y
Defines the corner frequencies and slope for a particular segment of phase noise limit
lines.
The slope defines the slope of the limit line segment to the left of the corner frequency.
