The SLM 1453I is a basic signal analyzer that offers the standard features and fundamental analog and digital TV-RF channel measurements. It provides a numeric readout of the signal level dBmV, audio-to-video dB ratio (A/V), and carrier-to-noise dB ratio (C/N) of analog NTSC channels off-air or on cable. It provides average power dBmV, Digital Flatness dB, C/N, Emulated Bit-Error-Rate (BER) and digital quality assessment (Good, Marginal, Fail) analysis on digital TV channels off-air or on cable.
The SLM 1453I Signal Level Meter is the affordable answer to equipping the Installer and Service technician. The SLM 1453I will tune to any CATV channel in the spectrum from 5 to 878 MHz. In addition, frequency tuning allows the user to tune to any frequency to measure pilots, DMX carriers, converter control signals, or other carriers used in today's modern systems. The SLM 1453I also allows you to switch between US Cable, HRC, IRC and VHF/UHF channel plans, including 8-VSB HDTV Off-air channels, Custom, or build your own custom channel plan, right from the keyboard.
The basic tools required to perform a quality installation will include a signal level meter. The technician who can verify an installation with his signal level meter can be assured that he has completed a good installation that will continue to provide the subscriber with the quality pictures that subscribers expect today. Likewise, the service technician must rely on his signal level meter to troubleshoot problems in the distribution and drop system. The CATV system is very carefully designed to provide specific signal levels at every point in the system, from the Trunk or Node to the distribution amplifiers and the drop. The Installer and Service technician must be able to insure these levels meet the design criteria for trouble free and long-term subscriber service.
The SLM 1453I will allow you to test any RF connection in the distribution system on any channel as simply as tuning any TV set. The SLM 1453I tunes the entire CATV band of channels from channel 2 through channel 137; a full 878 MHz of tuning capability so that you can use the SLM 1453I on any system and measure the level on any converter channel, Band Edge, Premium or Pay-Per-View channel. Unlike many signal level meters, the SLM 1453I is handheld and a quality tool that will provide confidence to the user.
