WARRANTY

The FG2C and FG3C Function Generators are warranted against any defects of material or workmanship within a period of one (1)
year following the date of purchase of the Function Generator by the original purchaser or original user. Any Function Generator
claimed to be defective during the warranty period should be returned with proof of purchase to a Wavetek authorized Service Center
or to the local Wavetek dealer or distributor where the Function Generator was purchased. See maintenance section for details. Any
implied warranties arising out of the sale of a Wavetek Function Generator, including but not limited to implied warranties of
merchantability and fitness for a particular purpose, are limited in duration to the above stated one (1) year period. Wavetek shall not
be liable for loss of use of the Function Generator or other incidental or consequential damages, expenses, or economical loss or for
any claim or claims for such damage, expenses or economical loss. Some states do not allow limitations on how long implied
warranties last or the exclusion or limitation of incidental or consequential damages, so the above limitations or exclusions may not
apply to you. This warranty gives you specific legal rights, and you may also have other rights that vary from state to state.

CERTIFICATIONS AND PRECAUTIONS

This instrument is EN61010-1:1993 certified for Installation Category II, Pollution Degree II. All inputs are protected against
continuous overload conditions up to the limits of each function's stated input protection (see specifications). Never exceed these
limits or the ratings marked on the instrument itself. Always inspect your Function Generator, test leads and accessories for signs of
damage or abnormality before every use. If an abnormal condition exists (broken or damaged test leads, cracked case, display not
reading, etc.), do not use. Never ground yourself when taking measurements. Do not touch exposed metal pipes, outlets, fixtures,
etc., which might be at ground potential. Keep your body isolated from ground and never touch exposed wiring, connections, test
probe tips, or any live circuit conductors. Do not operate instrument in an explosive atmosphere (flammable gases, fumes, vapor,
dust.) Do not use this or any piece of test equipment without proper training.

DANGER High Voltage

WARNING: To avoid electrical shock, the power cord protective

grounding conductor must be connected to ground.

INTRODUCTION

The FG2C and FG3C Function Generators are stable low distortion instruments that generate sine, triangle, and square waveforms
in frequencies up to 3 MHz. The FG2C has amplitude, offset, and duty cycle controls. The outputs are Main(50Ω) and logic(TTL
and CMOS). The FG3C has the same capabilities plus internal Sweep(Log/Linear), Modulation (AM/FM), external VCF/MOD and
counter inputs and GCV output. The counter can be switched to measure and display the frequency of an external signal
up to 150 MHz.

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 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.

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 0.75mm 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 engaged in a live socket. Any rewiring must be carried out in
accordance with the information detailed on this label.

PRECAUTION ITEMS

(1) The DC OFFSET (11) knob, will provide a DC level voltage of ±10V (no load) or ±5V (50Ω load). However, the signal

amplitude plus the DC level, is limited to ±20V (no load) or ±10V (50Ω load). In case of over voltage, clipping will appear as
show n in Figure 6.

(2) The main OUTPUT terminal is calibrated into a 50Ω load. This indicates that the signal source impedance is 50Ω. The OUTPUT

terminal may be connected to any circuit input impedance, but output the voltage and terminal impedance will not be calibrated.
To avoid oscillation, the OUTPUT terminal should be connected to a 50Ω load (especially when using high frequency and square
wave output), and the connecting cable should be as short as possible.

(3) When the DUTY knob is full counterclockwise, the ratio of positive state to negative state, should not be less than 80:20. When

the DUTY knob is full clockwise, the ratio of positive state to negative state, should not be greater than 20:80. Square waves can
be expanded to pulse waves, triangle waves can be expanded to ramp waves, sine waves can be expanded to unsymmetrical sine
waves. The Figure 7 shows the effect of the DUTY control adjustment on different waveforms.

Figure 6 Figure 7

FUSE REPLACEMENT (See Figs. 2 and 4)
Preliminary: Disconnect test leads from circuit and Function Generator. Push Power Switch off and unplug the power cord from the

rear of the Function Generator.

Warning: Failure to turn off and remove power from the Function Generator before changing the mains power

fuse could result in damage to the instrument and the operator.
Fuse replacement: Remove the fuse by inserting a small flat blade screwdriver into the notch at the bottom of the mains power

connector socket. Slide the fuse holder out. Replace the fuse with one of the following:
115 VAC 50/60 Hz: T0.315A/250V fuse (5mm x 20mm), I.R. 100kA – Wavetek p/n 2400-05-0069, Littel Fuse p/n 218.315, or

Bussmann p/n. GDC-315mA.
230 VAC 50/60 Hz: T0.160A/250V fuse (5mm x 20mm), I.R. 100kA – Wavetek p/n 2400-05-0070, Littel Fuse p/n 218.160, or

Bussmann p/n. GDC-160mA.

Warning: Use only an equivalent fuse to the one specified. Use of an incorrect fuse could result in serious injury or even death.
Reassembly: Slide the fuse holder back into the fuse cavity and reconnect the power cord.
MAINTENANCE & REPAIR

If there appears to be a malfunction during the operation of the Function Generator, the following steps should be performed in order
to isolate the cause of the problem: ① Review the operating instructions for possible mistakes in operating procedure. ② Inspect and

test the Test Cables for a broken or intermittent connection. ③ Inspect and test the fuse. See Fuse Replacement. Except for the
replacement of the fuse, or test cables, repair of the Function Generator should be performed only by a Factory Authorized Service

Center or by other qualified instrument service personnel. The front panel and case can be cleaned with a mild solution of detergent
and water. Apply sparingly with a soft cloth and allow the function generator to dry completely before using. Do not use aromatic
hydrocarbons or chlorinated solvents for cleaning.

INHALT

GEBRAUCHSVORBEREITUNG – AUSPACKEN

Die Verpackung sollte enthalten: ein Funktionsgenerator, ein Meßkabel von 1 Meter Länge (BNC nach Krokodilklemme), ein
Stromkabel, eine Ersatzsicherung und diese Anleitung. Sollte ein Teil fehlen oder beschädigt sein, bringen Sie das Gerät zur
Kaufstelle zurück für einen Umtausch.

EINLEITUNG

Die Funktionsgeneratoren FG2C und FG3C sind stabile Instrumente mit wenig Verzerrung, welche Sinus-, Dreieck- und
Rechteckwellenformen bis zu 3 MHz erzeugen. Das FG2C hat Kontrollen für Amplitude, DC Komponente und Tastverhältnis.
Ausgänge sind Hauptausgang (50Ω) und Logic-Ausgang (TTL oder CMOS). Das FG3C hat die gleichen Eigenschaften, plus interner
Wobbel (Log/Linear), Modulation (AM/FM), externer VCF/MOD, Zählereingang und GCV (Spannung proportional zur Frequenz)
Ausgang. Der Zähler kann zum Zählen einer externen Frequenz bis zu 150 MHz verwendet werden.
