The GB-4000 was designed after careful and thorough research to include the features and capabilities required by today's Frequency Generator users. The GB-4000 is the only Frequency Generator available that has all these features and specifications.
|
 | Frequency range of 0.1 to 20 million hertz. |
 | Can output Audio and high RF frequencies. |
 | 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 the same harmonics as a ray tube. |
 | 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 in RF mode. |
 | 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 other audio frequency generators. |
