TRILITHIC
6 – General Information
SPECTRUM DISPLAY
Press the
SPECT
button to display the
spectrum measurements with frequency
spans from 2 MHz to 50 MHz or a full-
spectrum 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 single-
channel 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 non-
volatile 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 trouble-
shooting 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.
