FAST ComTec represents in Germany, Austria and Switzerland  products from Berkeley Nucleonics Corporation (BNC).  There is a large product range available from General purpose Pulse Generators to Digital Delay Generators. Random-, Tail-, Ramp-, Delay-Generators and optical Modules as Benchtops or as NIM-Modules. 

The benchtop pulse generators feature a fast risetime and low jitter. Our most popular digital delay pulse series 575 and 577 generators are now available with selectable time references. With up to eight channels of delay and width control, each individual channel's reference can be set either to the trigger or to any other channel. So look below if you require a picosecond pulse generator or nanosecond pulse generator for your application. 

Introducing a Digital Delay/Pulse Generator with Optical Outputs

BNC offers optical outputs to trigger, delay, gate and sync multiple devices for use in high EMI and RFI environments. Optical outputs allow distribution over longer distances while maintaining the precision timing and coherence between channels.

The Model 575 and 577, BNC's latest digital delay/pulse generators, provide the ability to select timing references for each channel, to sum the timing  

of the various channels onto any other channel as well as to control both the delay and width of each channel, provide unique properties such as divide by N, independent channel gating, and independent channel amplitudes and polarities.

Copper cables are not suited for long distances and noisy environments. Copper cables can couple external noise onto its signal line. Over long distances, signals in coax and twisted-pair are attenuated and bandwidth-limited which results in width, jitter and timing errors. Level discriminators at the end of a copper cable will provide increased jitter when faced with a slower leading edge. Similarly, the timing will be delayed or in the extreme ignored due to slower leading edges.

"This optical output solution addresses our customers' need", stated John Yee, Sr. Applications Manager. "We have picked a transmit-receiver family that can be used in a variety of applications and can offer   even more connector and speed options. We can also provide optical triggering of our unit".

BNC's 575 / 577 optical options allow you to combine both optical and electrical outputs in pairs. For example, on a four-channel device, 2 or 4 of the channels can be optical. The wavelength and light properties selected are also compatible with Fast Ethernet standard 100Base-SX.

We offer BNC pulse generators only if end users are in Europe, other customers please contact BNC directly.
