Hi all,
I am now testing a DVB-T system on a STB. The hardware configurations
are:
SAA7130 + TDA10046 + TD1316
I used a DVB-T modulator to generate DVB-T signals (with a 4MBit bitrate
TS stream, single programme).
But when I use "tzap" to lock the corresponding frequency (only one
single frequency available on the transmission line, which is only 1
meter long), the screen dump are:
< snip. >
status 1f | signal afaf | snr ffff | ber 0000004e | unc 00000000 |
FE_HAS_LOCK
status 1f | signal afaf | snr ffff | ber 0000004a | unc 00000000 |
FE_HAS_LOCK
status 1f | signal afaf | snr ffff | ber 0000004c | unc 00000000 |
FE_HAS_LOCK
status 1f | signal afaf | snr ffff | ber 0000004c | unc 00000000 |
FE_HAS_LOCK
status 1f | signal afaf | snr ffff | ber 00000040 | unc 00000000 |
FE_HAS_LOCK
status 1f | signal afaf | snr ffff | ber 00000040 | unc 00000000 |
FE_HAS_LOCK
status 1f | signal afaf | snr ffff | ber 0000004c | unc 00000000 |
FE_HAS_LOCK
status 1f | signal afaf | snr ffff | ber 00000040 | unc 00000000 |
FE_HAS_LOCK
< snip. >
The "ber" field is quite strange, I do not know are there any users
notice these status responses? Should the "ber" field is zero for a good
signal?
And any other abnormal state shown on the above screen dump? Please
help.
Thanks.
Best regards,
Lo Chun Chung
