SOLT : Short-Open-Line_Thru (SOLT) is a calibration
(common coaxially) with simple and redundant
standards. It is not band-limited. It requires
well-defined standards. It has lower accuracy at
higher frequencies, and is poor with on-wafer.
TMA : A Tower Mounted Amplifier (TMA) amplifies
signals from an antenna to reduce the noise figure
of a base transceiver station (BTS). This helps to
improve the overall sensitivity of the BTS. A TMA
is a low-noise amplifier (LNA) that is usually
mounted as close as practical to the antenna in
Base Transceiver Stations or in mobile masts.
When using a TMA, the antenna is able to receive
weaker signals.
VBW : Video Bandwidth (VBW)
VSWR : Voltage Standing Wave Ratio (VSWR)
