numbers, but they are usually stored in text files and displayed in
human-readable notations, such as decimal nnn.nnn.nnn.nnn or
172.16.255.1 (for IPv4), and hexadecimal
nnnn.nnnn.nnnn.nnnn.nnnn.nnnn.nnnn.nnnn or
2C01:AB18:0:1234:FF03:567C:8:1 (for IPv6). In IPv4, each decimal
group (nnn) represents values from 000 to 255, or binary values of 8
bits. In IPv6, each hexadecimal group (nnnn) represents values from
0000 to FFFF, or binary values of 16 bits (0000 0000 0000 0000 to 1111
1111 1111 1111).
IPv6 : Internet Protocol Version 6 (IPv6) is a numerical label that is used to
identify a network interface of a computer or other network node
participating in an IPV6-enabled computer network. IPv6 uses 128 bits
for the address (as compared to an IPv4 address, which is defined as a
32-bit number). Pv6 was developed in 1995, and it is standardized as
RFC 2460. V6 began being deployed worldwide in the year 2000. I
addresses are binary numbers, but they are usually stored in text files
and displayed in human-readable notations, such as hexadecimal
nnnn.nnnn.nnnn.nnnn.nnnn.nnnn.nnnn.nnnn or
2C01:AB18:0:1234:FF03:567C:8:1 (where FFFF [Hex] = 65535 [Dec]).
Ea hexadecimal group (nnnn) represents values from 0000 to†FFFF, or
binary values of 16 bits (0000 0000 0000 0000 to 1111 1111 1111 1111).
LST : Line Sweep tools (LST) is PC-based post-processing software that
efficiently manipulates line sweep and PIM traces for reporting
purposes.
NF : Noise Figure (NF) is a measure of degradation of the signal-to-noise
ratio (SNR) that is caused by components in a radio frequency (RF)
device. The noise factor (F) of a system is defined as the signal-to-noise
ratio of the input power of the system divided by the signal-to-noise
ratio of the output power of that system. F (the noise figure) is defined
as the decibel value of the noise factor. NF = 10log (F) where log uses
the base 10, or common log. This formula is valid only then the input
termination is at standard noise temperature.
OBW : Occupied Bandwidth (OBW) is a measure of the bandwidth containing
99% of the total integrated power of the transmitted spectrum, centered
on the assigned channel frequency. Interference to other channels or to
other systems can occur if OBW is too large.
OSL : OSL or Open Short Load calibration method for coaxial line types.
Calibrations standards with known reflection coefficients are used to
calculate the correction factors. Refer to Calibration. Compare this with
SSL or Offset Short 1, Offset Short 2, Load calibration method for
waveguide line types.
