GENERAL
INFORMATION
Introduction
Congratulations! You now own Trilithic’s Model One 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 eight “favorites”), or as a full-span display. It also features a single channel SPECTRUM Mode which displays the presence of interfering beats in addition to the carrier amplitudes. The unit enables you to take the direct power measurement of QAM signals, carrier-to­noise measurements, data logging and also supports a voltmeter function.
The Model One makes it easy to obtain a hard copy of installation data or documen­tation of a problem via its printer function. By connecting the unit to a serial printer, you can download its display or records. If you are using a parallel printer, you can print out the records.
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. It’s tough, plastic shell and protective jacket make the Model One 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 One is rugged and convenient to use. It weighs only 1.5 lbs and can be carried and operated with one hand. All measurement functions are accessible via a single keystroke. Other functions are simplified through the combination of dedicated function keys and “softkeys”.

LEVEL MEASUREMENTS
The Model One can display a single channel, groups (up to eight) of “favorite” channels or all channel amplitudes.
The channel plans for the display can be configured either on the unit’s front panel or downloaded from a PC.
Single Channel Display
When tuned to a single channel, the Model One displays bar graphs for the video and audio carriers. It also shows numeric readouts of the carrier amplitudes and V/A difference. In addition, the unit provides a spectral display of intermodulation products or other undes­ired signals that may be present.
TILT AND “FAVORITE” GROUP DISPLAY
Press the TILT button to display a graph showing the amplitudes of up to eight user-selected video carriers. This display also shows the calculated difference in amplitude (tilt) between the HIGHEST and LOWEST channels in the user-selected group. Press TILT again and the Model One displays a numeric list which shows the amplitudes of the carriers in the group.
SCAN DISPLAY
Press the SCAN button to display the full span of video carriers. This mode is useful to make a quick check of your system’s overall flatness and amplitude.
The Model One can be set to display both audio and video carriers at reduced frequency spans. This means that you can impose amplitude limits on the display. By using the unit’s frequency marker, you can zoom in on any suspect channel that appears in the display.

SPECTRUM DISPLAY
Press the SPECT button to display the spectrum measurements with frequency spans from 2 MHz to 50 MHz or a full­spectrum scan.
CARRIER-TO-NOISE (C/N)
Press the C/N button to measure the C/N ratio of the CATV transmission system.
DIGITAL CHANNEL MEASUREMENT
The meter includes a special single­channel mode that you can use to measure the actual power of a QAM signal. The display will show the actual shape of the modulation “haystack”. This feature provides you with a powerful tool for detecting in-channel unflatness or mismatches that might affect digital transmission quality.
DATA LOGGING
The Model One has the capability to store the amplitudes of all video and audio carriers. This means that up to 24 full data records can be captured in non­volatile memory and later uploaded to your PC for record-keeping.
Each record carries the time, date, and the configuration of the meter at the time of record capture. It also enables you to annotate the record with a title name or comment.
VOLTMETER FUNCTION
This meter is equipped with a built-in voltmeter which can be used for trouble­shooting power supplies or power drops.
The Model One displays the voltage as a bar graph and numeric readout. It can accommodate AC or DC voltages up to 120 Volts.
Model One Operating Manual ""! TRILITHIC 6 – General Information
PRINTER FEATURE
In addition to being able to upload data records to a PC, the Model One can also download records or it’s current display to a serial printer.
If you are using a parallel printer, the Model One can download records. This is useful to obtain an instant hard copy of your installation or to document a problem (see Printer Operation page 66 for more information).

NOTE: Since the Model One memo­rizes the video parameter set up, be careful not to set the display contrast too low. This may cause the liquid display to be too dim or not visible at all which can affect your meter’s operation.
SHUTDOWN TIME
The Model One’s automatic shutdown timer can be adjusted to one of several parameters. You may set it so that it will stay on until you manually turn it off.
You can also set it so it will shut off after there has been no key pad activity for a specified time interval (3 minutes, 5 minutes, 10 minutes or 30 minutes). By setting it to one of the timer shut offs, you can save battery power during periods of inactivity.
