CATV Signal Level Meter

LM838　

Features

LM838 can test CATV signal level both at channel and frequency mode. At SCAN mode, it can scan all channels and store signal level. At spectrum mode, it can carry out spectrum display and test for a certain frequency range. Also it can measure CATV TILT, C/N, trunk cable Voltage, ect. The big LCD clearly displays all testing results. It especially fit for CATV station as a professional measurement instrument.
At TILT mode it can be set 7 channels and this instrument can store 24 groups (100 channels per group). It has lots of menu of setup. the menu include: Auto off time setup; level unit setup; frequency step; TILT channel setup; channel amend; channel plan select; channel edit; channel sort; operator, etc.
