Engineering:BNC 575
BNC 575 is electronic test equipment by Berkeley Nucleonics Corporation. It is the 2007/2008 version of a series of benchtop digital delay generator/pulse generator that began with the BNC 400 and BNC 500 in 2000. This version improves upon the earlier designs with better resolution (250ps), more channels (up to 8, each with separate delay and widths) and more functionality (summed channels, more output and input options, more allowable communication protocols.) Channel-to-channel and external trigger jitter have both been significantly improved from earlier designs. The BNC 575 replaces the BNC 565 and BNC 555. New capabilities include int/ext clock for synchronizing and pulse picking, summing timing of several channels onto one, independent trigger and gate and selectable timing reference for each channel.
Features
The BNC 575 features a single timing board that is coupled to modular input boards and modular output boards. In this way the BNC 575 can be configured to have a number of different electrical and optical inputs and outputs. This designs also allows for customization of the unit. For example, optical outputs were developed to deliver timing pulses in a harsh electrical environment. The Gate input can be converted to a second Trigger input, and one can select which channel operates with which of the two triggers.
Personal Computer to Pulse Generator Communication-RS232, USB, Ethernet and GPIB The 575 comes standard with RS232 and USB; Ethernet and GPIB interfaces are optional. All menu settings can be set and retrieved over the computer interface using a simple command language. The command set is structured to be consistent with the Standard Commands for Programmable Instrumentation (SCPI). The syntax is the same for all interfaces.
