Seems like you have trouble with the signal? Or maybe with the PWM
parameter?
All I can say is: works for me:
$ czap zdf
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
reading channels from file '/home/js/.czap/channels.conf'
1 ZDF:394000000:INVERSION_OFF:6900000:FEC_NONE:QAM_64:110:120
1 ZDF: f 394000000, s 6900000, i 0, fec 0, qam 3, v 0x6e, a 0x78
status 1f | signal 8585 | snr c0c0 | ber 00029220 | unc ffffffff | FE_HAS_LOCK
