Description

Buffer Amplifier Box


 

Case:

You need to distribute a single output or a group of output signals to multiple locations.

The Wrong Solution:

Your typical option is a messy cluster BNC “T” Connectors!

 


Our Innovative Solution

The BUF100-series Buffer Amplifier Box is a family of rack-mountable, quad buffered output amplifiers wherein each input channel is routed to four (4) separate output connectors with each channel buffered through a unity gain amplifier.  This architecture allows four devices to be connected to a single input channel and, as each output is individually buffered, the disruption of one output will not affect the other outputs for that channel, i.e. if Ch2 Output B is shorted, Outputs A, C and D on Ch2 will not be affected.  Each input is a differential amplifier that will accept true differential or single-ended signals.
