The BNC 505-4C Four Channel Pulse Generator has multiple modes of operation and 16 different edges in a single instrument. As a pulse generator it provides rate, delay, width, and output adjustability with each channel. As a digital delay generator, model 505 provides fine resolution, timing, and low jitter.
The outputs are synchronized to one another with coherence of 5 ns. A channel’s timing can be referenced to any other channel or to the zero delay point (To) The edges are adjustable in 100 ns steps. Channels can be selectively gated, enabled / disabled. Each channel possesses separate output level and polarity characteristics along with system level gating capability. Model 505 provides the ability to store custom parameter settings which are able to be recalled for later use.
