1. General Introduction
DS2400B is new model with color screen and high
performance, which is developed for Analog TV
analysis by Deviser. This model can measure and
display most indexes of Digital TV (Channel Power);
Analog TV(Single-frequency Level, Carrier Level of Full
Channels Spectrum, HUM). Also DS2400B can
measure Trunk Voltage, Battery Voltage and
Frequency Spectrum Scanning.
DS2400B has RS-232 port for communicating with PC
and also the PC software – TOOLBOX which can make
files management and analysis.

1.1 Channel Measurement
DS2400B supports accurate signal level test in
analogue TV and single frequency modes.
For Analogue channels, you can get video level, audio
level and △V/A etc.
1.2 Tilt/Level List
Tilt/Level list test is the effective solution to check the
flatness and amplitude, and DS2400B support 12
channels tilt max.
1.3 Channel Scanning
DS2400B supports video and audio level display of all
channels, which could up to 160 channels most. Also
its zoom in/out of 5 levels and marker function make
your observation easier.
1.4 Spectrum Scanning
DS2400B has spectrum function, It provides several
spans, and two sample modes (AVG and PEAK).In

order to detect and know the interference, it has
peak-hold function which shows the difference
between peak spectrum and current spectrum by
marker and double-marker function.
1.5 Hum Measurement
HUM is also named as power supply hum modulation
distortion, which comes from the low-frequency
interference of power supply.
1.6 Limit Measurement
DS2400B 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 after the
testing, pass/fail indicator can be viewed.
1.7 Auto Test
DS2400B provides a convenient way to automatic test
the cable system. You can set up test items including
level, spectrum, limit test, HUM, tilt, etc. And the test
result will be saved automatically.

1.8 Voltage Measurement
DS2400B can measure battery voltage, trunk voltage
and identify AC or DC automatically of the cable
system.
1.9 Multiple User Channel
DS2400B can create five user channel plans max,
which contains digital channels or analog channels or
mixed channels. Also they can be switched easily. So it
is very suitable for multi-network maintenance.
1.10 File Management
DS2400B can store the results of channel level test, tilt
test, channel scanning, spectrum scanning and HUM
test for analogue TV channel. User can manage and
analyze these files via meter or PC.
1.11 Intelligent Power Management
DS2400B with full charged is able to work over 5 hours.
The power supply monitoring system will monitor the
status of power and ensure the instrument in power
