2 Features and Functions
Output Configuration
Introduction
This section contains the information to help you configure
the U2761A for outputting waveforms. You may not need to
change some of the parameters discussed here, but they are
provided so that you will have accessibility when needed.
Output Function
The U2761A can output five standard waveforms (Sine,
Square, Ramp, Triangle, and Pulse), and DC. You can select
one of the three built-in Arbitrary waveforms or create your
own custom waveforms. In addition, you can internally
modulate Sine, Square, Ramp, Triangle, and Arbitrary
waveforms using AM, FM, PM, FSK, PSK, or ASK. The linear
or logarithmic frequency sweeping is available for Sine,
Square, Ramp, Triangle, and Arbitrary waveforms.
The table below shows which output functions are allowed
with modulation and sweep. Each “V” indicates a valid
combination. If you change to a function that is not
applicable for modulation, or sweep; then the modulation or
mode will be disabled.
