The only Frequency  Generator capable of running 8 frequencies simultaneously

The GB-4000 FREQUENCY GENERATOR Technical Specifications
and Features………

  • Frequency range: 0.1 to 20 million hertz.

  • Frequency output: digitally accurate frequencies converted to analog using a DAC for full analog harmonics.

  • Carrier wave frequency: New 3.1 MHz RF (Radio Frequency) carrier which produces the harmonic sideband frequencies used in 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 low audio frequency generator.

  • Waveforms: Square and sine wave. Square to 150,000 Hertz. Sine to 20,000,000 Hertz.

  • LCD: Displays all frequencies on the LCD - not hidden program numbers like other frequency generators.

  • Programmable channels: 2000.

  • Channel capability: 48 frequencies in sequence or 8 groups capable of holding 8 frequencies each.

  • Computer software: GB-4000 programmable software included.

  • Output multiple frequencies: Up to 8 audio frequencies simultaneously.

  • Eight audio frequency range: 1 to 40,000 Hertz with 1/100th Hertz resolution.

  • Output RF multiple frequencies: 2.

  • Two RF frequency range: Up to 20 million Hertz.

  • Duty cycle capability: 10% to 90% square wave duty cycle (Other frequency generators typically can only run a 50% duty cycle)

  • Gating or pulsing range: 1 - 5000 hertz.

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

  • Channel sweep: Variable from 2 to 10,000 Hertz or 1 to 5000 Hertz + and - of the target frequency or frequencies in all 2000 channels.

  • Standard sweep: 1 to 20 million making it capable of running both narrow and broad range sweeps.

  • Converge sweeps: 2 frequencies from 1 Hertz to 20 million Hertz.

  • Outputs: Four - 2 red and 2 black (other frequency generators have only 2 outputs).
  • Power output audio mode: Varialbe - 0.75 watts or 36 volts peak to peak.

  • Power output RF mode: Variable - 3 watts RMS to 5.4 watts peak power.

  • Voltage output RF mode:Over 110 volts peak to peak making it 27 times
    more powerful that standard frequency generators.

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

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

Want more power than 5.3 watts peak power? Then the SR-4 may be what you are looking for. It was developed for those who want more power. It connects to the GB-4000 using a BNC cable and BNC connections. Like the GB-4000 it outputs through wires to deliver its frequencies. This method has been used for many years and works very well. To purchase the SR-4, 30 MHz 1-15 Watt RMS power or 30 watt peak power Amplifier for only $695.00*. (Sale Price $595.00 when purchased with GB-4000)
