The GB4000
The only Frequency Generator capable of running 8 frequencies simultaneously.
20Mhz Sweep Function Generator
The GB-4000 is capable of outputting all frequencies from .1 to 20 million hertz.
The GB-4000 is also capable of sweeping from .1 to 20 million hertz.
New GB4000 Training Video
Finally here's a video showing how I use the MOPA Oscillator/Amplifier along with the GB4000 Frequency Generator. Let me know if this opens up any new questions for you. (the extended "Inside" video is coming soon along with the "Register for this site" feature very shortly - give me a few days on that!)
This video shows the basic and more advanced functions of the GB4000 Frequency Generator to give you an idea of how it works. The focus gets clear after about 2 min 45 seconds (just in time ;-)
thanks for watching!

GB-4000 Specifications
20 Megahertz Sweep/Function Generator
The only Frequency Generator capable of running 8 frequencies simultaneously.
The GB-4000 is the only FREQUENCY GENERATOR available that………
- Frequency range of 0.1 to 20 million hertz.
- Produces digitally accurate frequencies converted to analog for full analog harmonics.
- Incorporates a 2.4 MHz RF (Radio Frequency) carrier wave technology.
- Carrier wave can be turned off so user can use it as a standard low audio frequency generator.
- Produces square wave harmonics..
- Displays all frequencies on the LCD - not hidden program numbers like other frequency generators.
- Allows you to program your own frequencies and groups of frequencies (2000 custom channels available, each channels stores up to 48 frequencies).
- Computer programmable software included.
- Runs either single or multiple frequencies (up to 8 frequencies simultaneously).
- Capable of running a 90% duty cycle (almost double the power of other instruments; other frequency generators typically can only run a 50% duty cycle).
- Incorporates gating capabilities from 5 - 2500 Hz with a 10 - 90% duty cycle.
- Capable of running both sine wave and square wave waveforms.
- Channel sweep capabilities in all 2000 channels.
- Capable of running both narrow and broad range sweeps.
- Capable of running converge sweeps to 20 million hertz.
- Offers 4 outputs (other frequency generators have only 2 outputs).
- 9 times more powerful than any audio frequency generator.
Why Power 0utput 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 that do not use an RF carrier frequency is only about 0.20 of 1 watt. The GB-4000 with the use of an RF carrier is about 2 watts and is over 9 times more powerful than these instruments. With the use of the optional SR-4 amplifier it is over 50 times more powerful.
