How to Connect Two or More Sig

Introduction
A single-channel function generator or arbitrary
waveform generator meets the needs of most
engineers most of the time. But occasionally you face
a measurement challenge where you need to have
two or more source channels locked together in
frequency and phase.
To deliver maximum performance at a reasonable
price, test-equipment manufacturers design most
function generators with a single channel. Single-
channel instruments can be simpler and easier to use
than multi-channel instruments. In an environment
where engineers tend to share test equipment, it
makes sense to purchase single-channel sources and
use two single-channel sources in tandem when you
need multiple channels, rather than spending a
limited budget on a single, dual-channel instrument.
With single-channel sources you can disconnect the
units and use them separately again when you are
finished.
This application note describes the steps you need to
take to connect two or more signal generators to
create a multi-channel waveform generator.
