2.3 Function details

1. The video signal testing function (NF - 705 including simulation standard definition

video CVBS, HD / 3 g - SDI HD video)

The built-in 3.5 inch TFT LCD screen, intuitive and convenient showed that the quality of the

camera video equipment such as ball machine images Can be measured, Test the analog video

signal, support NTSC/PAL image signal. also can directly test the HD/3g-SDI HD video signals,

support 720 p24, 25,30,50,60;1080 p24, 25,30,50,60;1080 i50, 60 frame rate, etc.

2. The video signal attenuation analysis function

Test whether video signal intensity attenuation is too high or not. As the video signal Cable is too

long cause decay, video signal attenuation can create image dim, reduce image dynamic range;

if Video signal too strong,will cause the virtual shadow,lower image quality.This item can capture

and analyze synchronization level signal test and analysis of synchronization Video signal

attenuation amplitude, help to analyze video cable quality construction personnel. If beyond the

normal range, the tester screen will have corresponding hints.

3. Cloud control function

Users can via this product RS485 interface to control cloud from top to bottom and turn around,

change times +/- : focus+/ aperture control,preset Settings and calls,address code set. Mainly

is the RS485 communication interface control; Support of RS485 protocol includes: Pelco D,

Pelco P, samsung, panasonic, Ming jing, Vito, Ann and more than 20 Kind of agreements, can

also according to customer demand to increase agreement;Support the baud rate include:2400,

4800, 9600, 19200.

4. The camera power supply function

This product is specially set up for the camera power supply DC12V/1 a power supply output port,

provide temporary for the camera. The power supply. mainly used in some cameras live

demonstration and test, at the same time, for some need to install the camera fields, because

there is no power supply prior to the implementation of the scene, must find a temporary power

supply for camera, it Plays a role of the power supply output.

5. Video color bar signal

This product can produce high standard color bar signal and white, blue, purple, green, yellow,

black, red seven color standard video signal, NTSC / PAL video signals, video signal is optional.

Video output to the external display device to help test Channel line,and the working state of the

display devices are in good condition or not.

6. Ethernet cable testing

Cooperate with parts of the network cable test head, which can realize visualized wiring and

wiring sequence, detection Cable is connected correctly or not, is open circuit or line order

wrong, etc.

7. RS485 protocol testing

This product can control testing equipment output of RS485 signals, detect the detailed data of

RS485 signal directly Shown on the screen,easy to get the capture and analysis to the signal data.

8. High precision digital multimeter functions (NF - 703, NF - 703)

Built-in high-performance, low power consumption, 3 3 / 4 a counting (4000) automatic range

digital multimeter, clear reading, Single test method,Can be used to measure the AC voltage,

DC voltage and resistance, on-off testing, diode,high measurement range and high accuracy

that more convenient construction personnel for efficient analysis and testing of the circuit.

9. The audio test

Built-in amplifier circuit, magnetic speaker within 1 w, front- end can connect microphones and

other audio signal test.
