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. 
 

Frequently asked GB-4000 Frequency Instrument questions.

Q1: Does the GB-4000 output its frequencies digital or analog? A: Analog. Q2: Does the GB-4000 use crystal controlled frequencies for high accuracy. A: Yes it does for the RF carrier frequency. The GB-4000 also goes beyond using crystal-controlled frequencies. It also uses digital frequencies output from a DSP (Digital Signal Processor). Q3: How does the GB-4000 frequency Instrument output its frequencies analog when they come from a digital DSP chip? A: The GB-4000 uses a DAC (Digital to Analog Converter).
