GDS-2000A Options Overview
The GDS-2000A has a number of options that can be installed to
increase the functionality of the base models. Some of the options
are hardware only, and some of the options require both hardware
modules and software to be installed. Below is a list of options
available for the GDS-2000A.
GW Instek will continue to develop modules and optional software.
Please see the GW Instek website or see your local distributor for
further updates.

Module Installation
Background
The GDS-2000A has a number of optional modules
that can be installed into the module slots on the
rear panel. These modules must be installed before
power up.
Note
The modules are not hot-swappable. Please ensure the
power is off before connecting or disconnecting any of
the modules from the rear panel.
Steps
1. Make sure the power is turned off before
installing any of the optional modules.
2. Slide the tabs holding the module cover to the
unlock position and then remove
3. Install the optional module. Be sure to make
sure that the groves on the module line-up to
the slots in the module bay.
4. Slide the tabs back into the lock position.
5. Install the corresponding optional software, if
any. See the next section for installation
instructions.

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.
