SAFETY INSTRUCTIONS

Double Insulated

Do not dispose electronic equipment as unsorted municipal waste. Please use a separate collection facility or contact the supplier from which this instrument was purchased.

Safety Guidelines

General

Guideline

CAUTION

Do not place heavy objects on the instrument.

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.

Power Supply 

DC Input voltage: 5V/2A.

Do not exceed an input voltage of 5V±5%.

WARNING

Fuse

WARNING

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.

Disconnect the power and all test leads before replacing the fuse.

Make sure the cause of fuse blowout is fixed before replacing the fuse.

Cleaning the function generator

Operation

Environment

Storage environment

AFG-125/225 Series Options Manual

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.

Location: Indoor

Relative Humidity: < 70%

Temperature: -10°C ~ 70°C

Disposal

SAFETY INSTRUCTIONS

Do not dispose this instrument as unsorted municipal waste. Please use a separate collection facility or contact the supplier from which this instrument was purchased. Please make sure discarded electrical waste is properly recycled to reduce environmental impact.

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.

OPERATION

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.

Tracking

S_Phase

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 will synchronize the phase of both channels.

Steps

1. From the first level AFG menu, press UTIL and then press Dual

Chan on the side menu.

31

AFG-125/225 Series Options Manual

2. From the side menu choose the relevant tracking function(s):

Turns frequency coupling on and sets the type of frequency coupling:

Offset: Sets frequency coupling as an offset.

Ratio: Sets frequency coupling as a ratio.

Turns amplitude coupling on or off.

Ampl Cpl: OFF, ON

Turns tracking on or off, or turns tracking on and inverts the output of the second output.

Sync Setup

Background

Sync Signal

Output

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.

Sine, Square, Pulse,

Ramp Source

For these types of waveforms, the sync output is a square wave pulse. The pulse is high for the positive transition of the waveform and low for the negative transition. The signal is a TTL level signal.
