KEYSIGHT U2761A 20 MHz USB Modular Function Generator

The Keysight U2761A is a 20 MHz USB modular function generator with arbitrary waveform and pulse generation capability. It can operate as a standalone or modular unit when used together with the U2781A USB modular product chassis. The U2761A adopts the latest direct digital synthesis (DSS) technology that digitally creates arbitrary waveforms and frequencies from a single fixed frequency source. DDS offers the precision of digitally controlled logic - increasing the stability while reducing the complexity of the generator. This generates an accurately stable output signal for clean, low distortion sine wave and square wave coupled with fast rise and fall time up to 20 MHz and linear ramp waves up to 200 kHz. The U2761A is able to generate pulses from 500 µHz to 5 MHz. Designed with variable period, pulse width and amplitude parameters, the U2761A is ideal for a wide range of applications demanding flexible pulse width signals. With internal AM, FM, PM, ASK, FSK and PSK modulation it is easy to modulate waveforms. The U2761A connects to the computer through Hi-Speed USB 2.0 connectivity.

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).
