Precision Waveform Generator

Description:

The NTE864 is a precision waveform generator in a 14–Lead DIP type package capable of producing

sine, square, triangular, sawtooth and pulse waveform. Its operating frequency can be selected over

eight decades of frequency, from 0.001Hz to 200kHz. The frequency of oscillation is highly stable over

a wide range of temperature and supply voltage changes. Both full frequency sweeping as well as

smaller frequency variations (FM) can be accomplished with an external control voltage. Each of the

three basic waveforms, i.e., sinewave, triangle and square wave outputs are available simultaneously,

from independent output terminals.

Applications:

D Precision Waveform Generation: Sine, Triangle, Square, Pulse

D Sweep and FM Generation

D Tone Generation

D Instrumentation and Test Equipment Design

System Description:

The NTE864 precision waveform generator produces highly stable and sweepable square, triangle,

and sine waves across eight frequency decades. The device time base employs resistors and a ca-

pacitor for frequency and duty cycle determination. The generator contains dual comparators, a flip–

flop driving a switch, current sources, buffers, and a sine wave converter. Three identical frequency

waveforms are simultaneously available. Supply voltage can range from 10V to 30V, or ±5V to ±15V

with dual supplies.

Unadjusted sine wave distortion is typically less than 0.7%, with Pin1 open and 82kΩ from Pin12 to

Pin11 (–V or GND). Sine wave distortion may be improved by including two 100kΩ potentiometers

between V_CCand –V (or GND), with one wiper connected to Pin1 and the other connected to Pin12.

Small frequency deviation (FM) is accomplished by applying modulation voltage to Pin7 and Pin8;

large frequency deviation (sweeping) is accomplished by applying voltage to Pin8 only. Sweep range

is typically 1000:1.
