LINEAR_FREQUENCY_SWEEP_GENERATOR
Frequency is swept from 400 to 600 kc electronically by using reverse-biased pn junction diode C as variable capacitor in oscillator V5. Frequency markers are provided. Output is amplified and filtered to give 6 w into 150 ohms with high purity of wave form.-M. M. Brady, Oscillator Design Using Voltage-Variable Capacitors, Electronics, 32:34, p 38-40.
