// measure.cpp
// (c) Mobilink Telecom Inc, 1999, 2000
//
// May 21, 2000
// Nick Steffen
//
// Contains the measurement object
//
// June 27, 2000
// Added SetCableLoss() & GetCableLoss()
//
// September 20, 2000
// Added different version of GetTxPower()
// It accepts a third parameter which determines whether,
// when the expected power is not within 3 dB of the actual power,
// the search direction is from 33 dBm to 0 dBm or the other direction.
//
// February 9, 2001
// Modified GetUpperRampStatus() to change T0 as a function of band
//
// February 15, 2001
// Modified GetUpperRampStatus() to change -0.5 dB to -0.55, and -7.0 dB to -5.7
//
// March 2, 2001
// Modified to use HP8960
//
// March 5, 2001
// Modified GetTxPower() for 8960 to correctly measure power when expected and actual are different.
//
// March 11, 2001
// Added logging to 8960 clauses.
