USER MANUAL

Please take a moment to review these safety terms and symbols which
may appear in this manual or on Equipment to prevent damage to the
Function Generators.

Measurement category I is for measurements performed on circuits not
directly connected to MAINS.
Measurement category II is for measurements performed on circuits
directly connected to the low voltage installation.
Measurement category III is for measurements performed in the
building installation.
Measurement category IV is for measurements performed at the source
of the low-voltage installation.

FOR UNITED KINGDOM ONLY

NOTE: This lead/appliance must only be wired by

competent persons

WARNING: THIS APPLIANCE MUST BE EARTHED

IMPORTANT: The wires in this lead are coloured in

accordance with the following code:

Green/ Yellow: Earth
Blue: Neutral
Brown: Live(Phase)

As the colours of the wires in main leads may not correspond
with the colours marking identified in your plug/appliance,
proceed as follows:

The wire which is coloured Blue must be connected to the
terminal which is marked with the letter N or coloured Blue or

Black.
The wire which is coloured Brown must be connected to the

terminal marked with the letter L or P or coloured Brown or
Red.

If in doubt, consult the instructions provided with the
equipment or contact the supplier.
This cable/appliance should be protected by a suitably rated
and approved HBC mains fuse: refer to the rating information
on the equipment and/or user instructions for details. As a
guide, cable of 0.75mm² should be protected by a 3A or 5A
fuse. Larger conductors would normally require 13A types,
depending on the connection method used.

Any moulded mains connector that requires removal
/replacement must be destroyed by removal of any fuse &
fuse carrier and disposed of immediately, as a plug with
bared wires is hazardous if a engaged in live socket. Any re­wiring must be carried out in accordance with the information
detailed on this label.

The wire which is coloured Green & Yellow must be
connected to the Earth terminal marked with the letter E or by

the earth symbol

or coloured Green or Green & Yellow.

2. INTRODUCTION

The GFG-8210A Function Generator is a stable low distortion
instrument which generate signals in the frequency range up to 10 MHz.
Typical applications include a wide range of audio response testing
applications, vibration testing, servo system evaluation, ultra sound
applications, and etc.

The instrument includes the following features: logarithmic and linear
sweep capabilities, together with a built in frequency counter. The
sweep capability simplifies the task of finding resonant points of speakers,
filter networks and other networks structures. An oscilloscope may be
connected to this instrument for the response to be displayed. The
counter can be switched to measure and display the frequency of an
external signal up to 150MHz.

z ADDITIONAL FEATURES

1. Low distortion waveforms (sine, triangular and square).

2. Signal output in eight decade stages, 0.1Hz to 10MHz.

3. Adjustable sweep time and sweep width both in linear and

logarithmic modes.

4. Duty cycle control with signal inversion capability.

5. External Voltage controlled Frequency (VCF).

6. A second output for TTL or adjustable CMOS pulses.

7. 50 ohm main signal output with DC offset adjustment and 20dB

attenuation capability.

8. Supplied with two BNC test leads and AC power cord set.
