The 7S14 uses tunnel diode | The 7S14 has two triggering modes: triggered and HF-sync. | ||
In triggered mode, the signal passes through two stages of | |||
[[MC1672]] ECL logic gate, and then into the [[155-0109]] trigger chip. | |||
In HF-sync mode, the 7S14 uses a [[BD4]] back diode (0.1mA, 3pF), and inductor, and a | |||
[152-0177-00]] tunnel diode (10mA, 4pF) to form an oscillator that oscillates | |||
somewhere between 16.5MHz and 25MHz. | |||
The sampler used by the 7S14 is a two-diode design. | |||
Each of the two input channels has its own sampler. | |||
