| GENERAL |
The Model LF 941D TV Signal Level Meter enables speedy and accurate measurement of VHF/UHF TV and CATV signals.
This level meter can measure levels of digital broadcast signals as well as conventional analog broadcast signals.
Since ten programmable channels are provided to store arbitrary frequencies, a pilot signal, FM broadcast signals, and frequently used frequencies can be stored. The large digital display for level readout and bar-graph level indicator for antenna installation enhance speedy and accurate level measurements.
This compact & lightweight level meter is ideal for VHF/UHF antenna and CATV installations. |
