船用HC-401型多功能测试仪
NMEA0183多功能测试仪是船舶行业通信、导航维修工程师的测试仪器，主要有四大功能:
1、NMEA0183数据检测：任何设备的NMEA0183数字信号(RS-232或RS-422或TTL电平)均可检测，在液晶 屏上可直接显示各种语句信息。
2、刪EA0183数据信号发生器：可模拟各种船舶通导设备产生的数字信号；例如：GPS导航信息、测深仪深 度信息、水温信息、计程仪速度信息、计程仪200脉冲信号、电罗经航向信息、磁罗经航向信息、气象仪风向 风速信息、AIS船舶信息、雷达跟踪目标数据信息、自动舵航迹跟踪信息、舵角信息等。
3、 NMEA0183信号波形检测：是一台小型的示波器，测试NMEA0183信号的波形幅度，数据脉冲宽度等。
4、 信标检测：可检测船舶VDR信标的工作状态，以确定当船舶遇险时信标能有效发送37.5KHZ的定位信号。

NMEA MULTI TESTER (HC-401)
NMEA0183 MULTI TESTER is the first choice of testing instrument for the communication and navigation maintenance engineers in ship industry. It has four main functions:
1,NMEA0183 data detection: any device's NMEAO183 digital signal (RS-232 or RS-422 or TTL level) can be detected, on the LCD screen can directly display all kinds of statement information.
2,the NMEAO 183 data signal generator: digital signal can simulate all kinds of ship navigation equipment produced; for example: GPS navigation information, sounding depth information and temperature information, log information, log 200 pulse signal, gyro compass, magnetic compass information information, meteorological instrument wind information, AIS ship information and radar tracking the target data information, automatic tracking information, rudder rudder angle etc..
3,NMEAO 183 signal waveform detection: is a small oscilloscope, testing NMEAO 183 signal waveform amplitude, data pulse width, etc..
4,beacon detection: can detect the ship VDR beacon working state, to determine when the ship is in distress, the beacon can effectively send 37.5KHZ positioning signal.
