Can we use Dreambox DVB-S2X Si 21662 Rev B4 dual multistream tuner with DM7020HD

Zitat von gutemine

I'm pretty sure that it works also in 820 and 7080 as I use it heavily

Not In 820HD, I don't have 7080 and can not say

on the other hand si labs 2166 used In 900 UHD Is working without Issues I reported
so there Is something not updated In firmware used for 800se, 7020HD, 820HD

I use 7020HD with tuner A - BCM4505 and tuner B1 and B2 - silabs2166

1) from these two tuners obviously one Is not calibrated as they display very different values when used with same cable

2) from all 0.25 dB steps I have not seen more than 2 pcs 0.25 dB values when I used tuner In DM820 few days ago In latest original dream multimedia Image
once again tuner Is not calibrated and Is not working properly at all In 12 - 12.4 GHz - tested on 12.129 on Astra 2E

dual dvb s2 sil labs 2166 tuner does not output correct SNR levels

1) problem - signal SNR Is displayed with lower level than correct actual SNR - % and dB
for example tuning to transponder with FEC 5/6 - you can watch picture without break ups at 4.9 dB

2) problem - there are SNR levels are not displayed at all - for example there Is no 5.0 or 5.1 dB etc - from 4.9 dB you are jumping at 5.2 dB after that there Is no 5.3 dB but 5.4

dvb s2 BCM 4505 tuner does display SNR levels perfect - both % and dB

Dream Multimedia, please correct 1) and 2) problems for dual dvb s2 sil labs 2166 tuner

Hi

It Is known fact that after a FPGA updata new Vu boxes got much better tuner sensitivity
can you try to Improve tuner sensitivity of BCM4505 tuners - via driver or fpga updata or hardware

regards

there are some boxes that got problems with transponders with tuner B at 30000 sr
I heard that that applies to db7020hd too
I like to know as I think to buy that box
