Introduction
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 with the U2781A USB modular product
chassis.
Various features of the U2761A
–– Latest DDS technology adoption for
more stable and accurate output
signal
–– Easy-to-use arbitrary waveform
editor for easy customization of
waveform generation
–– Built-in modulation capability eliminates the need for a separate
modulation source
–– Pulse generation up to 5 MHz with variable period, pulse width, and
amplitude that are ideal for wide variety of applications
–– Wide range of Application Development Environment (ADE)
compatibility
–– Low start-up cost with standalone capability
–– Flexibility in expanding your application when using it as modular unit
with the U2761A
–– Command logger function offered in the bundled software allows easy
command conversion into VEE programs
Direct digital waveform
The U2761A adopts the latest direct
digital synthesis (DDS) technology
that digitally creates arbitrary
waveforms and frequencies from a
single and fixed frequency source.
DDS offers the precision of digitally
controlled logic—reducing the
complexity of the generator while
increasing the stability. Thus, allowing
you to have a stable, accurate output
signal for clean, low distortion sine
waves and square waves with fast
rise and fall time up to 20 MHz and
linear ramp waves up to 200 kHz.
Pulse generation
The U2761A can generate pulses
from 500 μHz to 5 MHz. With variable
period, pulse width, and amplitude
parameters, the U2761A is ideally
suited to a wide variety of applica-
tions requiring flexible pulse width
signals.
Internal modulation
Internal AM, FM, PM, ASK, FSK,
and PSK modulation makes it easy
to modulate waveforms without
the need for a separate modula-
tion source. Linear and logarithmic
sweeps are also built in, with sweep
rates selectable from 1 ms to 500 s.
Arbitrary waveform editor
With every purchase of the U2761A,
it is bundled with an easy-to-use
application software, the Keysight
Measurement Manager. This
application allows customization of
waveforms generation.
