Si2166D precision

  • I have DM 525 HD and now new DM Two UHD.

    DM 525: 4.3.3r3-2021-10-29; image Experimental 2017-07-20

    DM Two: 4.5.1r11-2021-10-29; image Experimental 2021-11-22

    DM 525 has BCM73625 (G3) (DVB-S2) tuner where signal is displayed with 0.01 dB precision

    DM Two has Si2166D (DVB-S2) where signal is displayed with 0.25 dB precision

    e.g I have the same channel connected to both tuners (same dual converter) and first displays 14.17 dB (87%) and second 14.00 dB (87%)

    I doubt older DM 525 tuner is better than new DM Two tuner :smiling_face:

    What is cause of such difference? Is this by design, software issue or my configuration issue?

    Thanks for helping!

  • This is just a converter showing this information. So you can't really do a compare like that.

    Use a Satfinder tool and check your true signal in the cable if you really need full correct information.

  • Not even sure it's the same. As you self write one calculate at 0.01 and the other 0.25 then of cause the decimals would be different :winking_face:

  • No I don't know how they calculate, but I can see values via e.g. webif at the same moment: I have connected both tuners to one converter with two outputs. 525 to B and Two to A and I earlier I had 525 connected to A and same result. My question is about displaying these values by Dreamboxes, not about calculating.
