8656B Agilent RF Generator
The 8656B is a 990 MHz RF Generator from Agilent. An RF generator is a tool engineers use to generate sinusoidal outputs while testing electronic equipment. The output will automatically have its frequency varied or swept between frequencies. A “sweep” is one complete cycle of a frequency variation. Engineers use RF signal generators as test equipment, mostly to measure responses of filters, amplifiers, and electrical components.
- Frequency range: 100 kHz to 990 MHz
- <35 ms frequency switching speed
- ±1 dB level accuracy
- Amplitude offset and phase adjust capabilities
- 150 millisecond frequency switching speed
- Versatile simultaneous modulation including dc FM
- Fully HP-IB programmable
The Agilent 8656B provides frequency coverage from 0.1 to 990 MHz (with underrange to 10 kHz). This wide range covers the IF and LO frequencies as well as the RF frequencies of most receivers. It also allows testing in a variety of communication systems including the 800 MHz FM mobile band. Frequency resolution of 10 Hz allows convenient setting of increments including narrow channel spacings, while characterization of phase sensitive devices is made easier with the help of the phase increment/decrement feature.
The Agilent 8656B provides precise output control. In addition, its modulation capabilities include simultaneous and mixed modulation modes from internal (400 Hz and 1 kHz tones) and external sources. These features create a versatile signal generator for use in a variety if applications.
