GB4000 MOPA New Frequencies Video

The Most Versatile Frequency Generators

In this video you'll see me share some new frequencies which came from a reliable source. Due to the controversial nature of this tech if you want more details you'll have to contact me privately for more information on how I use these.

If you've been on the fence about getting a machine, keep in mind we are currently towards the final stretch of a sale on these machines which we've only had once ever few years so now is a great time to consider it. Keep in mind that we back these systems with a 60 day satisfaction guarantee and a full 2 year parts and labor warranty.

Questions? Call Us At 541-434-0318

We are one of the original, and highly experienced distributors of the GB4000 and MOPA machines in business since 2001 (actually longer if you include our previous company). You can expect top notch service, exclusive training videos and other surprise bonuses. You'll have a full 60 day satisfaction guarantee and a 2 year parts a labor warranty.

We're recently back on adwords - thank you for visiting and considering us for this important purchase. Contact us through the site if you have any questions.

And by the way, none of the other e-commerce websites are the actual manufacturer.  One of them might 'seem' like they are based on the name but we are all independent distributors so when you decide on this purchase you're deciding on who you trust for the best support.

What will my investment be?

First of all a reminder that the prices don't include the accessories or plasma tube (only needed for MOPA) as those are available from 3rd party companies. Those cost $118 and $335 respectively.

These systems are still the best bargain compared to all the other systems out there give us a call on the phone if you'd like to know why we say that.

Also when you contact us with questions about them you'll see why we're considered the company with the best support for these machines.

Now here are the details: GB4000/SR4 and MOPA Frequency Generators

GB4000 Frequency Generator

60 Day Satisfaction Guarantee from the most experienced distributor Future Tech Today Inc est 2001. Previous to that we were Teslatech back in the 1990's ;-)


The only Frequency Generator capable of running 8 frequencies simultaneously. The GB4000 Function Generator incorporates years of research to produce all of the audio and RF frequencies to reproduce all the effects you've read about.

With class leading power output, and the ability to create all of the high frequencies used in the original machines, you will we be able to meet all of your frequency needs.


While almost all other machines can only run 1 frequency at a time, the GB4000 gives you the ability to run from 1 to 8 frequencies simultaneously for a superior multi-frequency waveform. Since the GB4000 is up to 10 times more powerful than other machines there is plenty of power available to run 8 frequencies at the same time.

Key benefits of the GB4000

    •
  • Voltage output in Audio Mode: 36 volts peak to peak which is .75 watts
    •
  • Voltage output in RF mode: Over 110 Volts peak to peak making it 18 times more powerful than most other frequency generators on the market. (Power output with the SR-4 Amplifier is up to 350 volts making it 75 times more powerful than our top competitors)
  • Full LCD Display - no hidden programs like with other frequency machines
    •
  • Channel sweep capabilities in all 2000 channels. Channel sweep from 1 to 20,000 Hz
    •
  • Capable of both narrow and broad range sweeps and even has an advanced "converge sweep" mode (ask us for details)
    •
  • Offers 4 outputs - other frequency generators only have 2
    •
  • Runs square wave frequencies up to 100 kHz and sine wave frequencies up to 20 MHz
    •  Note: Accessories not included (please inquire for details. *Unless unused returns subject to a 10% restocking fee. We've supported these machines for well over a decade and know them well so you'll be in good hands when you have questions.

    All our GB4000’s now ship with the groundbreaking 3.1 MHz RF Carrier Frequency. This RF Carrier optimizes the delivery of historical sideband frequencies. This recent discovery has now been incorporated into the GB4000. The 3.1 MHz RF Carrier is the optimal frequency for both sweeps and frequency programs.

    The GB-4000 is capable of outputting all frequencies from .1 to 20 million hertz in .01 Hz increments! (new)

    The GB-4000 is also capable of sweeping from .1 to 20 million hertz.

    How does the GB4000 stack up to the competition?

    • More Power (see below)
    • Wider Frequency Range (.1 Hz to 20,000,000 Hz range)
    • More Versatility (can add a MOPA Amp to run a plasma tube!)
