These companies manufacture oscillators, frequency sources, and frequency
synthesizers. Oscillators come in many varieties with many different frequency
determining devices. Everything from low-tech LC (inductor-capacitor) tank circuits
to crystals and YIG type oscillators are used. High and low accuracy and stability,
frequency ranges, fixed frequency and variable frequency, are among the available
options. If you are looking for test
