Function Generator Operation
Overview
Background The DDS Function Generator module allows the
GDS-2000A to create basic sine, square and
triangle waveforms.
Note
The function generator option can only be used
with firmware version 1.13 or later. However it is
highly recommended that firmware version V1.16
or later be installed to access the full functionality
of the module. The instructions on the following
pages are based on V1.16 or later.
Please see the GW Instek website for the latest
firmware and the firmware installation procedure.
