Tsys
Calculate system noise temperature from AOS data.
This one is too complicated. Use
qTsys,
or even better, use
Noise. It's also possible to
calculate noise temperature using
LinPlot.
Syntax:
Tsys
Options:
/diode,
assume cold/hot from noise diode
Thot=T,
hot temperature for receiver tests. default 295K
Tcold=T,
cold temperature for receiver tests. default 80K
zero=x,
limit considered to be zero to avoid error: default 1.0E-6
infinity=x,
highest noise temperature allowed: default 1.0E5
Tmm=[lower,upper],
override plot window range for Tsys
/gain,
plot the gain as well.
This is intended for noise measurements of the LNA using
a noise diode.
HotWhich=n,
the spectrum to use as hot spectrum: default read file hotspec.aos
ColdWhich=n,
the spectrum to use as cold spectrum: default read file coldspec.aos
AddComs=S,
additional comments for the plot. The variable
S is a string, or an array of strings.
PSfile='filename.ps',
filename for postscript output of Tsys
/showspectra,
plot the hot and cold spectra (default, no)
TsysAOS=T,
The Tsys data is returned in the variable T. This
can then be used in as input to
BackendOverplot.
/nowrite,
don't write out the tsys.aos file: default write it.
