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.

! TRILITHIC Model One Operating Manual

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.

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

A “P” for PASS or “F” for FAIL appears for
each channel selected by the marker.
This indicates that the channel meets the
requirements which were set up in the
LIMITS EDIT menu: minimum video level,

maximum ∆ video level, maximum ∆
video/audio difference, and minimum ∆

video/audio difference (see page 26).

A PASS (P) or FAIL (F) indication is also
given for the displayed scan spectrum.
This will indicate “–” until the first scan is
completed. The channel status of a “DIGI”
or “SNGL” type channel is not used to

OPERATION

Introduction

Once you have studied the Model One’s
basic operation (see Chapter 4 page 37),
you can proceed with more complex
operations.

Transmission Characteristic
Test

The Model One enables you to test for the
transmission characteristics of your CATV
device via it’s scanning frequency network
analyzer function. One of the primary
needs of a CATV system is to ensure the
quality of the signal transmission.

The meter enables you to do this by
measuring the gain distribution of the
transmission line and loss insertion by
measuring the transmission characteris­tics and loss insertion for cable, branch
line, distributor, amplifier, etc. The Model
One utilizes the signal of your CATV
headend to acheive this.

To test the transmission characteristics,
you first need to enable the TRANSMIS­SION option.

Press the SET button.

Press F2 or F3 to scroll to MEASURE­MENTS and then press F1 (ENTER) to
select that screen.
