LEVEL TEST
The DS1151B takes accurate signal level test on
analogue TV, QAM and single frequency channel.
When turned to a channel, the levels of video and audio,
△V /A also with the peak-hold level and △Peak–Peak
value can be easy displayed. To get more details of a
channel, a single channel SPECTRUM mode is
supported at level function.
Eight base channel plans and up to five user plans are
provided. You can determine the user plan automatically
by a special fast building mode.
The test data of level measurement can be saved and
printed out to a serial or parallel printer.

CHANNEL SPECTRUM SCANNING
A full span of audio and video carriers can be displayed
efficiently. You can zoom in or out for 5 levels to
observe the overall flatness and amplitude of your
system. By using marker, you can change the scanned
channels and read out the test data of video and audio
carriers. At most 150 channels are supported in SCAN
mode.
It is easy to save the scanning data or print it out in
report format.
FREQUENCY SPECTRUM
Frequency spectrum is applied ranging form 2.5 MHz to
62.5 MHz, or according to selected user plan. To
determine the problem of disturbance, the peak-hold
level spectrum can be enabled, and two curves are
displayed in one screen. One is for the real test spectrum,
another is for the peak-hold level spectrum. You can
read out the test data and frequency by marker and delta
maker function. Especially, the data of frequency
spectrum could be saved and printed out.
TILT/LEVEL LIST
To fast check the flatness and amplitude, the
4
TILT/LEVEL LIST function is favorite for you. The
level of up to 12 channels can be displayed as spectral
graph or in level table by pressing the TILT button. You
can save or print the test data of TILT/LEVEL LIST
measurement as you like.
C/N
C/N test on line is supported by the meter. To get the
more accurate C/N data, the method of shutting off
carrier is enabled.
DATA LOGGING
Up to 110 files can be saved in one meter depending on
the size of the saved files.
You can select and save the test data of LIMIT TEST,
LEVEL mode, SCAN mode, SPECTRUM mode, TILT
mode or all of them in one file. The file name can be
determined directly to define the saved contents, and the
saved files can be transmitted to PC for data analysis.
AUTO TEST
DS1151B provides a convenient way to automatic test
the cable system according to test commands edited by
user. You can select the test items including LEVEL,
5
SPECTRUM, LIMIT and TILT. Automated tests can be
executed immediately and the test data will be saved
automatically.
LIMIT TEST
You can fast check the cable system by the limit test
function. Each enabled channel will be tested according
to the limits set by user, and marked by pass /fail
indicators. Limit test results are video level, audio level,
△V/A, and pass/fail indicator can be viewed on the
LCD screen.
VOLTMETER
The problem of power supplies or drops can be found
out by a built-in voltmeter of DS1151B with voltages
ranging from 0 to 100V.
PRINTER OUTPUT
You can get a hardcopy of the saved file by a serial or
parallel printer, and the measured data can be printed in
report format. It is useful to document a problem.
QAM MEASUREMENT
The instrument is capable of measuring the actual power
of QAM signal, and showing the shape of the
6
modulation wave. This function takes it enable to detect
the flatness of the QAM signal and found out the
problem of the digital transmission system.
MULTIPLE USER PLAN
You can build up to five user plans in one instrument. It
makes it easy to quickly select the correct user plan for
the cable system at which you are working.
INTELLIGENCE POWER MANAGEMENT
To conserve battery life, the difference power supplying
method is used for difference working condition. The
instrument can work with the built-in battery for 6 hrs
on maximum power supply status. When working in
power saving mode, part circuits of the meter will
power down automatically.
FAST CHARGE
The meter has the capability to full charge the battery
during 3hrs. A specified charger is used, and the
charging time, temperature, voltage and charging
current are detected when charging. The charging
process will be stopped automatically as soon as the full
charge is detected.

3.1 INTRODUCTION
Now you can use the DS1151B according to the
description of chapter 3. Each measurement mode can
be accessed via buttons on the keypad, and it will be
discussed with detailed descriptions on how to perform
the measurement. But before the test operation, It is
important to make the meter to be compatible with your
cable system by learning your user plan at first.
3.2 LEARN USER PLAN

Figure 3-19
To build a new zero reference data according to the
signal of CATV system, you need to connect the cable
with the RF input port of the meter. You may have a
noise generator (such as DS5032). You can connect the
noise generator with the meter and power on the noise
generator.
Press F1(ENTER), the DS1151B scans the amplitude
automatically according to the video carriers of
selected user plan. The span of spectrum measurement
will be set as full span of selected user plan. After

*Serial printer cable—P.310075L25
(5pins Din connector to 25pins D-sub male
connector)
Connect the Din connector end to the instrument and
D-sub connector to the printer, select the right printer
type, enter the LOAD mode and select the desired file to
begin the printing operation.
To print the report by parallel printer, a parallel printer
adapter and data cable are needed.
*Parallel printer adaptor--0115005
(9pins D-sub connector to 25pins D-sub connector)
