DAC Controls Precision UHF Noise Level

Flat (±0.1dB) from 1 to 500MHz, Stable to 1:104; Noise Generator Proves That Vacuum Tubes Aren't Dead

The vacuum tube is making one of its last stands in the form of a high-precision noise generator for frequencies up to UHF. While solid-state noise generators are smaller, lighter, more robust, and less thirsty for power, the thermionic diode is an absolute standard. Read full article
