Case study:

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

The wrong approach:

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

Our innovative solution:

The BUF100 Sonoran Buffer Amplifier series represents  a family of rack-mountable, quad buffered output amplifiers where each input channel is routed to four (4) separate output connectors and each channel buffered through a unity gain amplifier. This architecture allows connecting four devices to a single input channel. Each output is individually buffered. The disruption of one output will not affect other outputs for that channel. For example – 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.

Buffer amplifier configuration:

20KΩ differential input impedance
10KΩ single-ended input impedance

* Satisfactory with most of low impedance S/C outputs
* Higher impedance configuration available upon request

X 1, Unity Gain Input range +/-30V 10KOhm input impedance

  • Gain accuracy – 1.000 ±0.1%, typical
  • Up to sixteen (16) differential input channels
  • Four (4) short circuit protected outputs
  • Better than -100 dB noise floor – better than ideal 16 bit ADC resolution
  • Bandwidth – DC to 200K Hz ±1 dB
