Technical Specifications:

• Stand Alone Frequency Generator: Unlike some generators on the market today, the GB-4000 was designed to be a simple to use, easy to operate, stand-alone frequency generator requiring no complicated computer interface to use all of its features. Computer operated generators generally work well but many people do not feel comfortable having to use a computer to operate all of a frequency generator's options. Our customers appreciate that they are not required to have a computer to operate any of our instrument's capabilities. The computer software for programming frequencies into the GB-4000 is an option, not a necessity. Its software was designed specifically not to be a hard to use computer interface. But it is for programming channels with frequencies and restoring any lost programmed channels that may be accidentally deleted by the user.
