thanks for response, i know how to do home certification, i"m doing every job, but take time at least 3 to 5 min to lock up,
is it possible just conect to the cable coax which is conect to the modem or emta, an then see wht"s my power level for upstream ,down stream, and snr?
same as test signal level in channel 2, it give you +18, or +4 or......,
i can go to the »
192.168.100.1 and cjeck the level,
but i realy need to learn this way with meter, if can i catch it fast less than 10 secound would be great.
