The 8642M is a 2.1 GHz 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.

The Agilent 8642M Signal Generator has a frequency range of from 100KHz to 2GHz and frequency resolution of 1Hz at all frequencies. The output is leveled and calibrated from +15dBm to -140dBm at all frequencies. Amplitude Modulation, Frequency Modulation, and Pulse Modulation modes are selectable. Frequency, modulation modes, output level, and most other functions can be remotely programmed via the interface.
