Sweep function generator

with built-in frequency counter

This function generator provide a substan-

tial array of output capabilities. It’s

extremely reliable for heavy day-to-day

usage in electronic troubleshooting, pro-

duction manufacturing test or as a bread-

boarding signal source.

The FG3C Sweep/function generator

ovides sine, square, triangle waves and TL

and CMOS pulse outputs fr

om 0.3 to 3 MHz.

A built-in frequency counter with 6 digit dis-

play accurately shows frequency setting. Or

use as stand-alone frequency counter for

external signals from 5 to 150 MHz. Control

the linear or logarithmic sweep of any of the

selected signal outputs internally or with

user provided external modulating signal.

Produce TTL or CMOS pulses with the duty

cycle function. Switchable 20dB attenuator

allows for low level signal output.

• Square, Triangle, Sine waves, TTL and

CMOS pulse outputs

• 0.3 Hz to 3 MHz range

• Linear or logarithmic sweep

• Amplitude or frequency modulation

• Built-in 150 MHz frequency counter

with 6 digit LED display

• Voltage controlled frequency (VCF)

input

• Two switchable 20 dB attenuators

• Signal polarity invert button

• Variable duty-cycle

• Variable dc V offset

• Includes line cords and fuses for either

117 V or 220 V operation
