General Description

1.1 INTRODUCTION

The Model 2001A is a very useful instrument for any test
requirement. It is a easy to use, compact 0.2Hz to 200KHz
Function Generator.

This manual contains information pertaining to the specifications,
installation and operation of 200KHz Function Generator
Model 2001A.

1.2 APPLICATIONS

The function generator can be used to test the frequency
response of low frequency amplifiers, attenuators, filters, etc
besides being a source of the most commonly used waveforms.
TTL output is provided to synchronise other circuitry or for
direct use with logic circuits. SWEEP IN terminal can be used
to sweep the output frequency using external voltage.

Installation

2.1 INSPECTION

The instrument is packed in a corrugated sheet box. As soon
as the unit is received, carefully open the box and inspect it
for any damage that may have occurred during transit. Save
all packing material. If any damage is found, notify the
carriers and our authorised representatives or ourselves
immediately. Also check whether all the specified accessories
are present.

2.2 POWER REQUIREMENTS

The instrument operates over a nominal 115V ±10%, 60Hz or
230V AC ±10% 50Hz AC line. A power cord has been provided
to connect the instrument to proper source.

2.3 SAFETY CONSIDERATIONS

2.3.1 Prior to applying power to the instrument, ensure that earth is
extended to the mains socket.

Intentional interruption of the grounding system, by use of
two-wire plug adapters or two wire extension cords must be
considered an unsafe practice.

2.3.2 Be sure that only correct fuse with proper V & A ratings is
installed for replacement purposes. INCORRECT FUSE
RATING CAN RESULT IN FIRE &/OR SERIOUS DAMAGE
OR HARM TO HUMAN LIFE & PROPERTY.
