LM828
Signal level meter is specially designed and manufactured for CATV system
installation and testing. It's a portable instrument, easy to carry with
many functions.
This instrument can test CATV signal level both at channel and frequency
mode. At SCAN mode, it can scan all channels and store signal level. Also
it can measure CATV TILT, C/N, trunk cable Vo1tage, etc. The LCD clearly
displays all testing results. It especially fit for CATV station as a
professional measurement instrument.
At TILT mode it can be set 2 channels and this instrument can store 13
