The only Frequency Generator capable of running 8 frequencies simultaneously.

The GB-4000 is the only FREQUENCY GENERATOR available that………

• Frequency range of 0.01 to 20 million hertz.
• Produces digitally accurate frequencies converted to analog for full analog harmonics.
• New! Incorporates a groundbreaking new 3.1 MHz RF (Radio Frequency) carrier wave technology to give massive versatility in sideband frequencies when using squarewave audio frequencies.
• 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.
