Calibration Files
All Paragon4 unit firmware comes bundled with two interpolation files used for
forward and reverse power calibration. These files are required to be used with
the optional external power sensor assembly (p/n 030 03547-xxx).

Caution: Forward & reverse power readings will not be accurate without the
optional external power sensor assembly (p/n 030 03547-xxx).

Calibration Files
Special electrical sensors are used to measure the values of real world quantities such as forward or re-
verse RF power. These sensors represent all measurements in Volts and require a conversion to proper
units where applicable. This conversion is achieved by use of mathematical transfer functions, which also
provide a way of calibrating the sensor hardware.
verse RF power. These sensors represent all measurements in Volts and require a conversion to proper
units where applicable. This conversion is achieved by use of mathematical transfer functions, which also
provide a way of calibrating the sensor hardware.
The transfer function can be represented by a simple look-up table that approximates a continuous func-
tion by a series of data points. Each data point represents an {X
tion by a series of data points. Each data point represents an {X
in
, Y
out
} pair, where X
in
is the sensor’s
output-a measurement in Volts, and Y
out
is the corresponding value in a desired unit of measurement. Li-
near interpolation is used to generate Y
out
values for any given X
in
value in between the data points sup-
plied in the look-up table.
The series of data points in a look-up table are listed in a text calibration file and is read by the Piecewise
Linear Interpolation Calibrated Conversion (PWLICC) software module, employed in Paragon4 radio
base station to convert the sensor output into a desired value.
