** Name: MT_TunerGain (MT2060 only)
**
** Description: Measure the relative tuner gain using the demodulator
**
** Parameters: hUserData - User-specific I/O parameter that was
** passed to tuner's Open function.
** pMeas - Tuner gain (1/100 of dB scale).
** ie. 1234 = 12.34 (dB)
**
** Returns: status:
** MT_OK - No errors
** user-defined errors could be set
**
** Notes: This is a callback function that is called from the
** the 1st IF location routine. You MUST provide
** code that measures the relative tuner gain in a dB
** (not linear) scale. The return value is an integer
** value scaled to 1/100 of a dB.
