
Do not place flammable objects on the
instrument.

Avoid severe impact or rough handling that
may damage the function generator.

Avoid discharges of static electricity on or near
the function generator.

Use only mating connectors, not bare wires, for
the terminals.

The instrument should only be disassembled by
a qualified technician.

DC Input voltage: 5V/2A.

Do not exceed an input voltage of 5V±5%.

Fuse type: F3.15A/125V.

Only qualified technicians should replace the
fuse.

To ensure fire protection, replace the fuse only
with the specified type and rating.

Cleaning the
function
generator
Operation
Environment

Disconnect the power cord before cleaning the
function generator.

Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid
into the function generator.

Do not use chemicals containing harsh products
such as benzene, toluene, xylene, and acetone.

Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (Note below)
and avoid strong magnetic fields.

Relative Humidity: < 80%

Altitude: < 2000m

Temperature: 0°C to 40°C
(Pollution Degree) EN 61010-1:2010 specifies pollution degrees and
their requirements as follows. The function generator falls under
degree 2.
Pollution refers to “addition of foreign matter, solid, liquid, or
gaseous (ionized gases), that may produce a reduction of dielectric
strength or surface resistivity”.
 Pollution degree 1: No pollution or only dry, non-conductive
pollution occurs. The pollution has no influence.
 Pollution degree 2: Normally only non-conductive pollution
occurs. Occasionally, however, a temporary conductivity caused
by condensation must be expected.
 Pollution degree 3: Conductive pollution occurs, or dry, nonconductive pollution occurs which becomes conductive due to
condensation which is expected. In such conditions, equipment
is normally protected against exposure to direct sunlight,
precipitation, and full wind pressure, but neither temperature
nor humidity is controlled.

AFG-125/225/125P/225P Overview
The AFG-125, AFG-225, AFG-125P and AFG-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 user manual will explain how
to become familiar with the arbitrary function generator modules.
The Getting Started chapter will introduce the modules with an
overview of the features and installation of the APP and
accompanying PC software. The Operation chapter will go over the
operation details.
Note1: The AFG-125/225/125P/225P are only supported with
GDS-2000A series DSOs with firmware version V1.19 or above
installed.
Note2: Throughout this manual AFG-125 will refer to both the
AFG-125 and the AFG-125P, unless stated otherwise. Similarly,
AFG-225 will refer to both the AFG-225 and AFG-225P, unless
stated otherwise.

DS2-FH1 Housing Installation
Background
Note
Steps
The DS2-FH1 consists of 2 housings that are
attached to the feet on the underside of the case.
Make sure the power is turned off before installing the
AFG-125/225 module.
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.

Module Installation/Removal
Background
Note
The AFG-125/225 modules are installed into the
area that is left between both of the DS2-FH1
housings.
Make sure the power is turned off before installing the
AFG-125/225 module.
Installation Steps 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.

Dual Channel Tracking
Background
Dual Channel
Functions
As only the AFG-225 has dual channels, it has a
number of tracking functions not available on the
AFG-125. The tracking functions are listed below.
Function
Description
Frequency Coupling Frequency coupling will
couple the channel outputs by
frequency. Frequency
coupling can be achieved by
frequency offset or by a
frequency ratio.
Amplitude Coupling Amplitude coupling will
couple the both channel
outputs by amplitude. Any
changes in amplitude in one
channel is reflected in the
other channel.
Steps
Tracking
There are two tracking modes,
ON and Inverted. When
turned on, tracking performs
frequency and amplitude
tracking so the channels
behave as a single channel.
When set to inverted, the one
channel will output the
inverse of the other.
S_Phase
S_Phase will synchronize the
phase of both channels.
1. From the first level AFG menu,
press UTIL and then press Dual
Chan on the side menu.

Sync Setup
Background
The sync output signal is output from the SYNC
port on the front panel. The sync output signal is
based on either the channel 1 or channel 2 output
signals. Each periodic type of waveform output
function has an associated sync output signal.
The characteristics of the sync output depend on
the selected signal source.
Sync Signal
Output
Sine, Square, Pulse, For these types of waveforms,
Ramp Source
the sync output is a square
wave pulse. The pulse is high
