GB-4000 Specifications and Features.....


  • Stand Alone Frequency Generator: Unlike some generators on the market today the GB-4000 was designed to be a simple to use, easy to operate, stand alone frequency generator requiring no complicated computer interface to use all of its features. Computer operated generators generally work well but many people do not feel comfortable having to use a computer to operate all of a frequency generator's options. Our customers appreciate that they are not required to have a computer to operate any of our instrument's capabilities. The computer software for programming frequencies into the GB-4000 is an option, not a necessity. Its software was designed specifically not to be a hard to use computer interface. But it is for programming channels with frequencies and restoring any lost programmed channels that may be accidentally deleted by the user.

  • Programmable channels: 2000.

  • Channel capability: 48 frequencies in sequence or 6 groups
    capable of holding up to 8 frequencies each. While almost all other manufacturers only run one frequency at a time the GB-4000 can run from 2 to 8 frequencies simultaneously, up to 40,000 Hertz and 2 frequencies up to 20MHz (20 million Hertz) for a superior multi-frequency waveform. With this frequency range, it has the ability to generate millions of frequencies which can be put into individual channels and run as sequences of individual or multiple frequencies.

  • Computer software: GB-4000 programmable software included.

  • Outputs: Four - 2 red and 2 black.

  • RF Mode Power output: Variable up to 4.7-watts power output.

  • Audio Mode power output: Variable up to 36 volts or 0.75 watts.

  • Voltage output in RF mode: Over 110 volts making it over 47 times more powerful than most standard frequency generators.

  • Frequency output: Digitally accurate frequencies converted to
    analog using a DAC (Digital to Analog Converter).

  • Frequency range: 1 to 20 million Hertz.

  • Two circuits capable of output frequencies.

  • "Audio Mode" circuit capable of outputting 8 frequencies simultaneously from 1 to 40,000 Hertz and 1 frequency up
    to 400,000 Hertz. This circuit uses no RF carrier frequency.

  • Eight audio frequency range resolution: 1/100th of a Hertz.

  • "RF Mode" circuit capable of outputing 8 frequencies simultaneously from 1 to 40,000 Hertz and two frequencies from 1 to 20 million Hertz.

  • Waveforms: Square and Sine wave. Square wave to 100,000 Hertz. Sine to 20,000,000 Hertz.

  • Duty cycle capability: 10% to 100% square wave duty cycle.

  • Gating or pulsing range: 1 - 5000 Hertz.

  • Gating duty cycle range: 10% - 90%.

  • Carrier wave frequency: Now with new 3.1 MHz RF (Radio Frequency) capable of producing harmonic sidebands like the 1930's, 1940's and 1950's equipment.

  • Carrier wave on and off capability: Carrier wave can be turned off
    so the user can operate it as a standard audio frequency generator.

  • Channel sweep: Variable- 2 Hertz to 20,000 Hertz or 1 Hertz to
    10,000 Hertz + and - of the target frequency or frequencies in all
    2000 channels.

  • Standard sweep: 1 to 20 million Hertz.

  • Converge sweeps: Two frequencies from 1 Hertz to 20 million Hertz.

  • L.E.D: RF indicator light confirms RF output.

  • Display: LCD.

  • AC adapters: Two switching 110/240 volt power supplies for
    worldwide use.

  • The GB-4000 is priced at $1825.00. This price includes shipping
    in the USA. Please contact your distributor to order the GB-4000.

Why Power Output Is Important
In A Frequency Generator!


When comparing the various instruments, power output is a very important consideration. This is the reason the GB-4000 uses a carrier frequency so that more power can be output.

The power output of most frequency generators on the market today which do not use an RF carrier frequency is only about 0.10 to 0.20 of one watt. The GB-4000 with the use of a 3.1 MHz RF carrier has a 4.7-watt power output and is from 23 to 47 times more powerful than these instruments. With the use of the optional SR-4 1 to 15-watts amplifier it is 75 to 150 times more powerful.

RF Variable Power Output Amplifier

The SR-4 was developed for those who want more power. It connects to the GB-4000 using a cable with BNC connections. Like the GB-4000 the SR-4 outputs through wires.

The SR-4 1 to 15-watts power amplifier only amplifies the RF (radio frequency) frequencies output by the GB-4000. The GB-4000 has two output modes call "Audio Mode" and "RF Mode". The SR-4 amplifies the "RF Mode" output of the GB-4000 from 4.7-watts to 15-watts depending on the frequency used.

In "RF Mode" the GB-4000 output power goes up to 4.7 watts. With the SR-4 amplifier it goes up to 15-watts of output power.

If you are looking for even more power and want the broadcast method then the 190-watt M.O.P.A. power amplifier is what you are looking for Click on the above M.O.P.A., tab and read more about the M.O.P.A.
