FIGURE 5.1 : TDA10021 MAIN USER INTERFACE WINDOW
Table 5.1 Descriptions for the TDA10021 main user interface window
Channel Configuration
RF in [MHz]
Set the RF input signal frequency in MHz
SR [Mbaud]
Set the symbol rate for the channel decoder in Msps
Modulation
Set the QAM format (4, 16, 32, 64, 128 or 256QAM)
Spectral inversion
Automatic search for spectral inversion or force the spectal inversion
Program Fron-End
Run the algorithms to lock the complete system
Channel Status
BER
BER indication after the demodulation (RS decoder input)
RF AGC / IF AGC
Value between 0 and 255 indicating the tuner AGC level. 0 = to much power/ 255
= not enough power
MSE
Mean square error indicating the signal quality (low MSE means good signal quality)
AFC=xxKHz
Indication of the corrected frequency drift in KHz
