BERKELEY NUCLEONICS CORPORATION 505-4C Four Channel Pulse Generator

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.

Channel Bandwidth
Channel Bandwidth is the bandwidth over which power is measured. This is usually the bandwidth in which almost all of the power of a signal is contained.

Jitter
Jitter in technical terms is the deviation in or displacement of some aspect of the pulses in a high-frequency digital signal. Jitter is the time variation of a periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals. Jitter is a significant, and usually undesired, factor in the design of almost all communications links (e.g., USB, PCI-e, SATA, OC-48). In clock recovery applications it is called timing jitter.

Overshoot
Overshoot is the distortion that follows a major transition; the difference between the peak power point and the pulse-top amplitude computed as a percentage of the pulse-top amplitude.

Rise Time
Rise time refers to the time required for a signal to change from a specified low value to a specified high value, usually 10 and 90 percent of pulse-top amplitude (vertical display is linear power).
