Displaying the carrier offset of the Doppler port in the DMU window 3.3.10.5
When using menus that support integrated phase measurement (see above), the display of the carrier
offset in the DMU window (see figure below) can be modified to take advantage of the accurate
estimate of the Doppler port.
By default, in these menus the carrier offset is computed using the default estimator.
The integrated phase estimator can be activated and the sampling period can be modified through the
Windows registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\IN-SNEC\CrtxHdr\SetDefault\Signal Processing\DMUX\Integ_Phase_Freq_Offset
With the following possible values:
0: Default estimator
1: Integrated phase estimator over 10ms period
2: Integrated phase estimator over programmable period (same as the Doppler port)
