Overview
Congratulations! You now own Trilithic’s
Model Two Signal Level Meter
. This instrument is
designed to provide you with optimal features for reduced cost.
Amplitude measurements are fast and efficient. Carrier amplitudes are displayed singly, as a
group (up to 12 “favorites”), or as a full-span display. This product also features a single-channel
Spectrum Mode, which displays the presence of interfering beats in addition to the carrier
amplitudes. The unit lets you take the direct power measurement of QAM signals, carrier-to-noise
measurements, data logging, and also supports a voltmeter function.
5 user-defined channel plans may be stored, and the Model Two can perform a complete test of all
channels in the selected User Channel Plan to specified limits at the press of a single key. It can
also be set to automatically perform Level, Spectrum, Tilt (Favorite), and Limit tests at
programmed intervals unattended.
The Model Two can save files for Level, Tilt, Spectrum, Scan, Limit Test, and Auto Test
measurements. These files can be recalled to display the recorded data, or Scan, Spectrum, and
Limit files can be viewed graphically. The Model Two also makes it easy to obtain a hard copy of
installation data or documentation of a problem via its printer function.
The unit is the ideal signal level meter for HFC installations. It is durable, has many features, and is
simple to use in a wide range of conditions. Its tough, plastic shell and protective jacket make the
Model Two highly resistant to damage from shock and impact. When not in use, the unit and its
accessories are contained in a carrying case.
The Model Two is rugged and convenient to use. It weighs only 1.5 pounds and can be carried and
operated with one hand. All measurement functions are accessible via a single keystroke, and,
with the Fast Setup function, settings for each measurement mode can be accessed at the press
of a single key without going through nested menus. Other functions are simplified though the
combination of dedicated function keys and “softkeys”.
