9th port receiver , BSR64K Motorola

Hello , does someone know who to use theus feature of the BSR64K ?, is there the need of using a software besides the configuration of the fft and snr made on the BSR? , I have noticed that when a display , for instance

BSR#fft display 2/1 startfreq 0 endfreq 81920000 table

Power Level Measurement - Slot : 2, Port : 1
==================================================

Number of Samples : 512, 9th Receiver Opmode : Tap-in
Window Coefficient used : Rectangular
Start Frequency : 0 Hz, End Frequency : 81920000 Hz
Frequency Step Size : 320000 Hz

Frequency (Hz) Power Level (dB)
-------------- ----------------
0 -39.9222
320000 -67.476
640000 -71.3327
960000 -78.0045
1280000 -84.2884
1600000 -90.309
1920000 -87.2987
2240000 -83.3193
2560000 -78.0045
2880000 -83.3193

3520000 -78.8477
3840000 -61.6698
4160000 -71.5009
..............................................
thouse level are the level of the signal reaching the CMTS on the upstream port ?, why are they negative ?

And , when I display for instance

BSR#snr display 2 7
SNR Setup: slot 2 upstream 7 Start Freq 5000000 End Freq 42000000 channel-width 6400000
modulation-type Auto ingress-cancel Auto equalization On

27400000 16QAM On On 33.8
27400000 16QAM On Off 33.3

why is there only thouse tyes of modulation if in a CMTS 2x8 Module I work with docsis2.0 and 64QAM, this can not give a real measure , there is no option to choose 64QAM.

I appreciate any response . Regards.

what sw are you running

Please post the output from show chassis stat and we can go from there

re sh chas stat

I wanted to see the type of cards, but you left of the software the system is running. could you report the output with the image as well?

Thanks
Carl
