Agilent N8201A Performance Downconverter Synthetic Instrument Module, 250 kHz to 26.5 GHz 133
Remote Command:
:CALCulate:LLINe[1]|2:DELete
Example:
:CALC:LLIN:DEL deletes limit line/margin 1 (LLIN defaults to Limit Line 1)
Freq Interp
This key is grayed out in the time domain (when the N8201A is zero span). Sets the
interpolation to linear or logarithmic for the specified limiting points set, allowing you to
determine how limit trace values are computed between points in a limit table. The
available interpolation modes are linear and logarithmic. If the linear (Lin) mode is used for
both frequency and amplitude, a straight line is used when interpolating between points in
a limit table. If frequency interpolation is logarithmic (Log), frequency values between limit
points are computed by first taking the logarithm of both the table values and the
intermediate value. A linear interpolation is then performed in this logarithmic frequency
space. An exactly analogous manipulation is done for logarithmic amplitude interpolation.
If two amplitude values are entered for the same frequency, a single vertical line is the
result. In this case, if an upper line is chosen, the amplitude of lesser frequency (amplitude
1) is tested. If a lower line is chosen, the amplitude of greater frequency (amplitude 2) is
tested.
For linear amplitude interpolation and linear frequency interpolation, the
interpolation is computed as:
For linear amplitude interpolation and log frequency interpolation, the
interpolation is computed as:
For log amplitude interpolation and linear frequency interpolation, the
interpolation is computed as:
For log amplitude interpolation and log frequency interpolation, the interpolation
is computed as:
