- In the circuit, R2, R3, R4, RP1, C1 and VT1 constitute a single junction transistor oscillator circuit, which is used to generate trigger pulses.
- When the capacitor is charged by R4 and RP1, the voltage Ue increases gradually.
- When the Ue reaches the peak voltage, e B1 turns on and the voltage on the capacitor outputs a pulse voltage to R2 via e-b1.
