CX180/E test sets when the units are equipped with the DOCSIS or Euro DOCSIS cable modem
options however the option is not available when the enhanced version below is fitted. The USG
frequency is adjustable from 5MHz to 42 MHz (US DOCSIS version) or 5 to 65 MHz (Euro DOCSIS
version) in 1MHz steps while the level is adjustable over a dynamic range of 5 to +58 dBmV in 1dBmV
steps
The
Enhanced USG + FEC
option is available for the CX120 and CX180 models only however the
cable modem and enhanced USG options are mutually exclusive for both CX120 and CX180. The USG
+ FEC option supports CW, QPSK, QAM-16, QAM-64 and QAM-128 signal generation. The USG
frequency is adjustable from 5MHz to 65MHz while the level is adjustable over a dynamic range of 68
dBuV to 119dBuV (8dBmV to 59dBmV)
If a digital modulation type is selected, then a symbol rate needs to be selected (160K to 2.56M) as well. The symbol rate depends
