Step 5
After sending the sine wave in the SICOFI-4 transmit path the result of the Level
Metering function will be present in the LMR bit of the configuration register CR2.
Examples for reading back the CR2 register:
0 0 1 0 0 0 1 0 = 22
0 0 1 1 0 0 1 0 = 32
Step 6
By programming different levels for the level metering function the actual PCM coded
level can be found. Also a change of the AX1 gain filter will change the PCM level in the
transmit path.
If an analog signal is applied to the SICOFI-4 analog input, the level of this analog signal
can be calculated. To calculate the analog level, the gain setting of the SICOFI-4 filters
together with the 0 dBm0 reference voltage have to be taken into account.
