OVERVIEW
The AFG-125/225/125P/225P are arbitrary function
generator modules for use with the GDS-2000A series
DSOs. The options require the DS2-FH1 module
extension bay to secure the module to the DSO. This
Quick Start Guide gives a quick overview to the
features, installation and basic operation for the AFG-
125/225/125P/225P. See the user manual for further
details.
The AFG-125P & 225P also incorporate a power supply
output with a selectable voltage output of 2.5, 3.3 or 5V.
The AFG-125/225/125P/225P are only supported with
GDS-2000A series DSOs with firmware version V1.19 or
above installed.

Installation
AFG APP Installation
The AFG-125/225 modules require a separate APP
installation.
1. Load the AFG.gz APP file onto a USB flash drive.
Insert the USB flash drive into the USB slot on the
front panel.
2. Press
Utility
> File Utilities. Select the AFG.gz
file on the USB flash drive.
3. Press
twice to install the AFG APP.
4. After the installation has completed, restart the
oscilloscope.
Installing the DS2-FH1
The DS2-FH1 consists of 2 housings that are attached
to the feet on the underside of the case.
1. Slip the housing over the front of the feet on the
GDS-2000A.
2. Make sure that the rear tab clips securely over the
fan vent grid on the rear panel, as shown below.

Installing the AFG-125/225 Module
The AFG-125/225 modules are installed into the area
that is left between both of the DS2-FH1 housings.
1. Slide the module into the slot that was created
between the DS2-FH1 housings. The front of the
module should be facing forwards.
2. Make sure the module is secure. The module will
click into place when it is inserted properly.
3. Make sure the GDS-2000A is turned off before
proceeding.
4. Connect one end of the GTL-254 USB cable to the
rear panel USB Device port and to the USB Host
port. Connect the other end to the Device port on
the AFG-125/225, as shown below.
5. Turn the power back on. The AFG-125/225 will
now be accessible in the Option menu.
Removing an Installed Module
1. At the rear of the housings are two tabs. Pull both
tabs outwards.
2. The module can now be slid out from the
housing.
USB Configuration
The USB Device port needs to be configured to provide
power for the AFG-125/225 if an external power
supply is not used.
1. As shown previously in the “Installing the AFG-
125/225 Module” section, connect the GTL-254
USB cable.
2. Press the
Utility
key and select USB Device
Port > USB Power.
The USB device port will now supply power to
the AFG-125/225.
Caution
The USB Device Port should be
reconfigured to “Computer” or
“Printer” when the AFG-125/225 is
not used. Failure to do so may damage
the PC or printer when connected in
the “USB Power” mode.
Accessing the Arbitrary Function Generator
Like all options, the AFG-125/225 options can be
accessed with the Option key.
1. Press the
O
key and select AFG.
The AFG-125/225 is now ready to be used.
Basic Waveform Selection
The AFG-125/225 options have five selectable basic
waveforms.
1. Select the output channel by pressing Signal 1
Setup or Signal 2 Setup.
2. Press Waveform Mode and select a waveform type
from the side menu.
Sine, Square, Pulse, Ramp, Noise
3. As appropriate, configure the frequency,
amplitude, offset and duty cycle/symmetry from
the side menu after a basic waveform is selected.
4. Press Go Back from the bottom menu to return to
first level of the AFG menu.
ARB Waveform
The following will describe how to create and output
an arbitrary waveform.
1. Select the output channel by pressing Signal 1
Setup or Signal 2 Setup.
2. Press ARB from the bottom menu. Press ARB on
the side menu and toggle ARB On.
3. Press Edit.
4. Press Edit Method and select the method to edit
the arbitrary waveform.
Point/Line: Creates pulses of a user-defined
length and amplitude.
Diagonal: Creates a diagonal line between
Addr1/Data1 and Addr2/Data2.
Scale: Scales the ARB waveform between
0.1X ~ 10X.
Copy /Paste: Copies a section of the ARB
waveform and pastes it to a section of the
ARB waveform.
5. Press Action to edit the ARB waveform using the
method selected above.
6. Press Output Confirm from the side menu. Set the
area of the ARB waveform to output. Press
Confirm to confirm the area to output.
7. Press more 1 of 2 and set the Frequency, Amplitude,
Offset and Rate of the ARB waveform.
Modulation
The following will describe how to modulate a carrier
waveform (shape) with the basic waveform shown
previously.
1. Select a basic waveform as shown previously.
This will be used as the modulating (baseband)
signal.
2. Press MOD from the bottom menu. Press MOD
on the side menu and toggle MOD On.
3. Select the type of modulation on the side menu:
AM, FM, FSK, PM, SUM.
4. Set the parameters for the chosen modulation
type from the side menu.
Sweep Modulation
The following will describe how to create a single
sweep waveform.
1. Press Sweep from the bottom menu. Press Sweep
on the side menu and toggle Sweep On.
2. Press Type and select Linear or Log.
3. Press Start to set the start frequency, press Stop to
set the stop frequency.
4. Press SWP Time and set the sweep time.
5. Press Span to set the Span.
6. Press Center to set the sweep center frequency.
