Noise Type File Format

Noise type filenames must begin with "WGN" and end with ".DAT". The first line in the
file is a value that represents the number of sample points in the file. The assumed
resolution is 0.01 dBm.
Each subsequent line will contain one data value in the assumed units of dBm, with lines
separated by a carriage return. The maximum range for the data values is determined by
the minimum and maximum Noise Density of the instrument.
A sample data file containing three sample points with a resolution of 0.01 dB is as
follows:
3
-130.00
-90.25
-90.75

Multipath Type File Format

All of the twelve paths in a multipath channel can be driven dynamically by a single data
file. During a dynamic run, the path values for path Doppler, Delay, Loss, and AoA are
modified sequentially according to the fading file values.
Multipath type filenames must begin with "MPF" and end with ".DAT". The first line in
the file is a value that represents the number of sample points in the file.
The second through thirteenth line in the file represents the path Type, Correlation Path,
Correlation Value, Rate, Std Dev, and K-factor settings, which remain fixed during a
dynamic run.
Each subsequent line contains Doppler, Loss, Delay and AoA values for each of the 12
paths. Each of these path settings must begin with a semi-colon delimiter ";" and use an
ASCII space character to separate the four values. If a path is off, the values between
semi-colons are ignored.
The assumed resolution, range and units for each value is as follows:
