Hi guys,
Link to the BNC switch project website
www.linkbone.comI want to share with you the project that I have been recently working on. The BNC switch with remote access via 10/100 Ethernet or RS-232 interfaces for measurement and test automation. This is an analog signal multiplexer allowing to do connect up to 15 signal points to one common signal line. This is a passive BNC switch for analog or digital signal routing. It can be used for making measurements with an oscilloscope at multiple test points. With signal generator connected, it can be used for routing system clock or any other signal. Please have a look at the attached picture with BNC switch example application.
Here are some preliminary specs/features:
- Bidirectional signal routing
- DC to 50Mhz bandwidth
- Accept voltages up to +/-24V with 1.5A load per channel
- 50Ohm channel impedance
- Http server with user configuration Web page
- Telnet server and RS-232 command line interface
- RC5 infrared remote control
- Touch screen on front panel for manual control
- 19-inch rack muting system
There is also a dual BNC switch version with two 1-to-15 multiplexers/demuliplexers signal networks. The device can be also used for video/CCTV switching. I have also made an XLR switch version for audio.
Currently first lot of BNC switch boxes is in PCB assembly. I post more information with signal measurements when I will have the devices ready.
In the blog section I have prepared few application notes with code examples:

PS I hope I will not be taken as a spammer. I was reading this forum for a very long time. But finally I have decided to register to tell you about my project.
