[linux-dvb] Tzap utilities questions - status of TDA10046

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
