Signal loss :
Signal loss is the amount of signal strength that is lost in antenna cable,
connectors, and free space. Signal loss is measured in decibels.
Smith Chart :
A Smith Chart is a graphical aid for electrical and electronics
characteristics in radio frequency (RF) circuits. Smith Chart was
invented by Phillip Smith at Bell Laboratories in 1939. The chart can be
used to display multiple parameters, such as impedance, and
admittance.
SOLR/SSLR/SSSR :
Short-Open-Line-Reciprocal (SOLR), Short-Short-Line-Reciprocal
SSLR), and Short-Short-Short-Reciprocal (SSSR) are calibrations
similar to SOLT/SSLT/SSST, but used when a good Thru is not
available. They have some accuracy degradation due to a less defined
Thru and have disadvantages of the parent calibration.
SOLT :
SOLT or Short Open Load Thru calibration method for coaxial line
types with simple and redundant standards. It is not band-limited. It
requires well-defined standards. It has lower accuracy at higher
frequencies. Calibrations standards with known reflection coefficients
are used to calculate the correction factors. Refer to Calibration.
Compare this with SSLT or Offset Short 1, Offset Short 2, Load, Thru
calibration method for waveguide line types.
SSL :
SSL or Short Short Load or Offset Short 1, Offset Short 2, Load
calibration method for waveguide line types uses Shorts with different
offset lengths. It is a calibration (common in waveguide) with simple
and redundant standards, but it is band-limited. It requires
well-defined standards. It has lower accuracy at higher frequencies.
Offset Short 1 is 1/8 wavelength, and Offset Short 2 is 3/8 wavelength.
Calibrations standards with known reflection coefficients are used to
calculate the correction factors. Refer to Calibration. Compare this with
OSL or Open Short Load calibration method for coaxial line types.
SSLT :
SSLT or Short Short Line Thru or Offset Short 1, Offset Short 2, Load,
Thru calibration method for waveguide line types uses Shorts with
different offset lengths. It is a calibration (common in waveguide) with
simple and redundant standards, but it is band-limited. It requires
well-defined standards. It has lower accuracy at higher frequencies.
Offset Short 1 is 1/8 wavelength, and Offset Short 2 is 3/8 wavelength.
Calibrations standards with known reflection coefficients are used to

OSLT or Open Short Load Thru calibration method for coaxial line
