      產品詳細介紹Product Introduction

      MSG-2192 is a signal generator which generates DSRC and pseudo signal of road side optical beacon unit. DSRC transmits and receives radio, optical beacon through downlink and uplink.
      It enables to conduct transmitting and receiving test of such as car navigation system and on board unit.

      Features

      • Transmitting data of DSRC and optical beacon can be written through dedicated application software.
      • There is no display or setting switches on the body. Use USB or RS-232 instead
      • With the dedicated application software, setting, DSRC and optical beacon input are easily carried by a PC.
      *No simultaneous output of both DSRC and optical beacon
      *No editing or creation of DSRC and optical beacon data by the dedicated application

      Notes for MSG-2192
      1. Optical beacon and DSRC are inspected without considering of onboard application.
      Normal inspection cannot be carried when in onboard condition (condition windshield between) hence considered this is out of warranty. In addition, DSRC inspection is not conforming to SPF authentication therefore data receiving cannot be made. DSRC inspection enabled standard connection sequence and WCNC reading inspection.

      2. Radio act
      As this product is not conforming to Radio act in Japan, take appropriate action, such as using electric wave anechoic chamber to prevent leakage of radiation.
