The GB4000 Frequency Generator Technical Specifications and Features…..
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.
- 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.
- Outputs: Four - 2 red and 2 black.
- Power output: Variable up to 2.7 watts.
- Voltage output in audio mode: 40 volts peak to peak.
- Voltage output in RF mode: Over 110 volts peak to peak making it over 9 times more powerful than
most standard frequency generators.
- Frequency range: 0.1 to 20 million Hertz.
- Frequency output: Digitally accurate frequencies converted to analog using a DAC.
- Output multiple frequencies: Up to 8 audio frequencies simultaneously to 40,000 Hertz.
- Eight audio frequency range: 0.1 to 40,000 Hertz with 1/100th of a Hertz resolution.
- Output RF multiple frequencies: Two.
- Two RF frequency range: Up to 20 million Hertz.
- Waveforms: Square and Sine wave. Square wave to 150,000 Hertz. Sine to 20,000,000 Hertz
- Duty cycle capability: 10% to 90% square wave duty cycle.
- Gating or pulsing range: 1 - 2200 Hertz.
- Gating duty cycle range: 10% - 90%.
- Carrier wave frequency: Now with new 3.1 MHz RF (Radio Frequency) capable of producing harmonic
sidebands like 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 audio frequency generator.
- Channel sweep: Variable- 10 Hertz to 10,000 Hertz or 5 Hertz to 5,000 Hertz + and - of the target
frequency or frequencies in all 2000 channels.
- Standard sweep: 0.1 to 20 million Hertz.
- Converge sweeps: Two frequencies.
- L.E.D: RF indicator light confirms RF output.
- Display: LCD.
- AC adapters: Two switching 110/240 volt power supplies for worldwide use.
- The GB-4000 is priced at $1725.00. This price includes shipping in the USA.
Please contact your distributor to order the GB-4000.
Why Power Output 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 a watt. The GB-4000 with the use of an RF carrier is about 2.7 watts and is over 13 times more powerful than these instruments. With the use of the optional SR-4 15 amplifier it is over 75 times more powerful.
SR-4 1-30 Megahertz Amplifier.
1-15 watts output.
Want more power than 2.7 watts? 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. This method has been used for many years and works very well.
The SR-4 1-15 watt amplifier only amplifies the RF (radio frequency) frequencies output by the GB-4000.
It amplifies the output of the GB-4000 from 2.7 watts to 15 watts depending on the frequency used.
In Audio Mode no RF carrier frequency is used. Also in Audio Mode the GB-4000 outputs 40 volts peak to
peak which is about 0.75 or 3/4 of a watt. The GB-4000 goes up to 40,000 Hertz in Audio Mode at 40 volts.
In RF Mode almost the full frequency range of the GB-4000 goes up to 110 volts. With the SR-4 Amplifier it
goes up to almost 15 watts or over 200 volts.
If you are looking for even more power and want the broadcast method then the M.O.P.A. 120 watt average power amplifier is what you are looking for. Click on the M.O.P.A. tab and read more about the M.O.P.A.
The Deluxe Travel Case
The deluxe travel case has wheels and an extendable handle like most fine luggage. It holds the GB-4000
and SR-4 amplifier along with all the accessories. The foam inserts protect the GB-4000 and SR-4 amplifier
better than any other case on the market. For those who want to protect their investment it is well worth
owning when you have to travel or if you just want to have a safe protective case to store your GB-4000
and SR-4 amplifier. Because of its size the deluxe case has to be sent Fed-X or UPS outside the U.S.
The price is $180.00.
The Compact Travel Case
The compact travel case is a smaller case than the deluxe case. Because of its small compact size it can
be shipped to almost any country through the USPS. It is ideal for those who want to be able to carry their
GB-4000 and SR-4 amplifier when they fly. It easily fits into the overhead compartments on any airline. It is
rugged, light weight and will protect the GB4000 and SR-4 with ease. The price is $140.00.
